Dual-Block Temperature Calibration from −15 °C to +350 °C
The Fluke Calibration 9009 combines two independently controlled temperature blocks in one portable instrument.
The cold block covers temperatures from:
−15 °C to +110 °C
The hot block covers temperatures from:
+50 °C to +350 °C
This arrangement allows users to perform calibrations at two different temperatures without waiting for a single calibration block to heat up or cool down.
For example, one temperature block can be set to a low calibration temperature while the other operates at a higher temperature.
This is particularly useful when checking the zero and span characteristics of industrial temperature transmitters.
The combined temperature coverage makes the Fluke Calibration 9009 suitable for many industrial calibration applications.
When the hot block operates at its maximum temperature of 350 °C, the minimum achievable temperature of the cold block is approximately −8 °C.
Two Independently Controlled Temperature Blocks
The main advantage of the Fluke Calibration 9009 is its dual-block design.
Each temperature block is equipped with an independent precision temperature controller.
This allows the two blocks to operate at different temperature setpoints.
The cold block can be used for low-temperature measurements, while the hot block provides elevated calibration temperatures.
Both blocks can operate simultaneously.
This reduces waiting times and improves productivity during repeated calibration procedures.
The independent temperature control also provides flexibility when calibrating different types of temperature sensors.
Four Calibration Wells
The Fluke Calibration 9009 features four calibration wells.
Each temperature block contains two wells.
This allows several temperature probes to be inserted into the instrument simultaneously.
Depending on the calibration procedure, the wells can accommodate reference thermometers and devices under test.
For example, one well can contain a calibrated reference thermometer while the second contains the temperature sensor being calibrated.
Alternatively, multiple temperature probes can be checked simultaneously using the calibrated temperature indication of the block.
For accurate comparison calibration, the reference thermometer and the device under test should be positioned under suitable thermal conditions.
Excellent Temperature Stability
Temperature stability is an important characteristic of a dry-block temperature calibrator.
The Fluke Calibration 9009 provides temperature stability of:
±0.05 °C
This specification applies to both temperature blocks under the manufacturer’s defined conditions.
Good temperature stability helps maintain nearly constant temperature conditions during calibration.
This reduces measurement uncertainty contributions caused by temporal temperature fluctuations.
The stability specification must not be confused with the display accuracy of the instrument.
Accurate Temperature Indication
The Fluke Calibration 9009 provides different display accuracy specifications for its two temperature blocks.
The manufacturer specifies:
Cold block accuracy: ±0.2 °C
Hot block accuracy: ±0.6 °C
These values describe the accuracy of the temperature indication under the specified operating conditions.
For applications requiring lower measurement uncertainty, an external calibrated reference thermometer can be used.
The external reference thermometer measures the actual temperature inside the calibration block.
This allows the indication of the device under test to be compared with a traceable reference temperature.
Well-to-Well Temperature Uniformity
The Fluke Calibration 9009 provides well-to-well temperature uniformity of:
±0.1 °C
This specification describes the temperature difference between the calibration wells under defined conditions.
Good temperature uniformity is particularly important during comparison calibration.
It helps ensure that the reference thermometer and the device under test are exposed to similar temperatures.
The actual temperature distribution can depend on probe diameter, insertion depth and thermal loading.
These effects should be considered when evaluating the measurement uncertainty.
Removable Calibration Inserts
The Fluke Calibration 9009 features removable calibration inserts.
The inserts allow the instrument to accommodate temperature sensors with different diameters.
The standard delivery includes:
- Two inserts with 6.4 mm openings
- Two inserts with 4.8 mm openings
Additional inserts are available for sensor diameters from approximately 1.6 mm to 11.1 mm.
The removable inserts provide flexibility when calibrating different temperature probes.
For accurate measurements, the insert opening should be selected to provide suitable thermal contact with the sensor.
Calibration Well Depth
The Fluke Calibration 9009 features calibration wells with a depth of:
102 mm
The available immersion depth is an important factor when selecting a dry-block temperature calibrator.
Insufficient immersion can cause heat conduction along the probe stem.
This may result in a difference between the actual sensing element temperature and the temperature of the calibration block.
For high-accuracy calibration, the required immersion depth should be evaluated according to the sensor construction and measurement conditions.
Portable and Rugged Construction
The Fluke Calibration 9009 is designed for demanding industrial environments.
The instrument is housed in a robust protective carrying case.
The manufacturer describes the enclosure as airtight, watertight and impact-resistant.
This construction helps protect the calibration equipment during transportation.
The compact dimensions are:
178 × 267 × 248 mm
The instrument weighs approximately:
4.5 kg
This makes the Fluke Calibration 9009 particularly suitable for portable calibration applications.
The carrying case also provides storage space for the power cable and additional calibration inserts.
Fast Heating and Cooling
The Fluke Calibration 9009 provides efficient heating and cooling performance.
The manufacturer specifies the following typical times.
Hot Block
Heating from 25 °C to 350 °C:
30 minutes
Cooling from 350 °C to 100 °C:
40 minutes
Cold Block
Heating from 25 °C to 110 °C:
15 minutes
Cooling from 25 °C to −15 °C:
16 minutes
The specified stabilization time is approximately:
8 minutes
Actual heating, cooling and stabilization times depend on operating conditions and thermal loading.
Calibration of Pt100 and RTD Sensors
The Fluke Calibration 9009 is suitable for calibrating industrial resistance thermometers.
Typical examples include Pt100 and Pt1000 temperature sensors.
The sensor under test is inserted into a suitable calibration well.
After the temperature has stabilized, the temperature indication of the sensor is compared with the reference temperature.
The indication error can be calculated as:
ΔT = T_DUT − T_REF
Where:
- ΔT = Temperature indication error
- T_DUT = Temperature indicated by the device under test
- T_REF = Reference temperature
The reference temperature may be obtained from the calibrated block indication or from an external reference thermometer.
Thermocouple Calibration
The Fluke Calibration 9009 can also be used for thermocouple calibration.
The thermocouple measuring junction is inserted into the calibration block.
The temperature is adjusted to the required calibration point.
The thermoelectric voltage is measured using a suitable instrument.
The measured value can then be compared with the expected thermoelectric voltage for the corresponding thermocouple type.
The measurement uncertainty must include the reference temperature, thermocouple measurement system and reference junction compensation.
Temperature Transmitter Calibration
The Fluke Calibration 9009 is particularly suitable for industrial temperature transmitter calibration.
Its two independently controlled temperature blocks allow low-temperature and high-temperature reference points to be prepared simultaneously.
This is useful for checking the zero and span characteristics of temperature transmitters.
For example, the cold block can provide a lower reference temperature while the hot block provides an upper reference temperature.
The transmitter output can then be evaluated at both calibration points.
When using transmitters with electrical output signals, an appropriate measuring instrument is required.
RS-232 Communication Interface
The Fluke Calibration 9009 features an integrated RS-232 interface.
This allows the instrument to communicate with a computer.
The interface can be used to monitor and control temperature setpoints.
It also supports automated calibration procedures.
The Fluke Calibration 9009 is compatible with MET/TEMP II software.
This allows temperature calibration procedures to be integrated into automated laboratory workflows.
NIST-Traceable Calibration Included
The Fluke Calibration 9009 is supplied with a NIST-traceable calibration for both temperature blocks.
The manufacturer specifies the following calibration points.
Hot Block
50 °C, 100 °C, 150 °C, 200 °C, 250 °C, 300 °C and 350 °C.
Cold Block
−8 °C, 0 °C, 25 °C, 50 °C, 75 °C, 100 °C and 110 °C.
The calibration provides documented measurement results and metrological traceability.
For applications requiring accredited calibration, the available calibration options should be checked separately.
