7109A provides outstanding temperature stability.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>0.01 \u00b0C<\/strong><\/p>\n<p>Temperature stability describes how much the bath temperature changes over time under specified operating conditions.<\/p>\n<p>High temperature stability is particularly important when several temperature sensors are calibrated simultaneously.<\/p>\n<p>A stable calibration environment reduces temperature variations during the measurement process.<\/p>\n<p>This helps improve the repeatability and reliability of comparison calibrations.<\/p>\n<p>For accurate measurements, sufficient stabilization time should be allowed after changing the temperature setpoint.<\/p>\n<h2>Excellent Temperature Uniformity<\/h2>\n<p>The Fluke Calibration 7109A provides excellent temperature uniformity throughout its specified working volume.<\/p>\n<p>The manufacturer specifies typical temperature uniformity of:<\/p>\n<p><strong>0.02 \u00b0C<\/strong><\/p>\n<p>Temperature uniformity describes the spatial temperature differences within the calibration bath.<\/p>\n<p>Good temperature uniformity is essential when multiple temperature sensors are calibrated simultaneously.<\/p>\n<p>If sensors are exposed to different temperatures, additional measurement errors may occur.<\/p>\n<p>The liquid calibration medium and integrated circulation system help provide a homogeneous temperature environment.<\/p>\n<p>This makes the Fluke Calibration 7109A particularly suitable for multi-sensor calibration

features a liquid bath with a fluid capacity of:<\/p>\n<p><strong>2.5 liters<\/strong><\/p>\n<p>The specified working area measures:<\/p>\n<p><strong>75 mm \u00d7 75 mm<\/strong><\/p>\n<p>The maximum fluid depth is:<\/p>\n<p><strong>154 mm<\/strong><\/p>\n<p>The tank opening measures approximately 112 mm \u00d7 112 mm.<\/p>\n<p>This spacious design allows several temperature sensors to be immersed simultaneously.<\/p>\n<p>The liquid medium provides good thermal contact between the reference thermometer and the devices under test.<\/p>\n<p>Compared with dry block calibrators, liquid baths offer advantages when sensors have unusual shapes, large process connections or different diameters.<\/p>\n<p>The actual usable working volume and immersion requirements must be observed when performing precision calibration.<\/p>\n<h2>Portable Temperature Calibration<\/h2>\n<p>Despite its high measurement performance, the Fluke Calibration 7109A is designed for portable operation.<\/p>\n<p>The instrument weighs approximately:<\/p>\n<p><strong>20 kg<\/strong><\/p>\n<p>Its dimensions are:<\/p>\n<ul>\n<li>Height: 382 mm<\/li>\n<li>Width: 242 mm<\/li>\n<li>Depth: 400 mm<\/li>\n<\/ul>\n<p>The compact design makes the calibration bath suitable for use in laboratories and industrial facilities.<\/p>\n<p>A fixed carrying handle allows the instrument to be transported conveniently.<\/p>\n<p>Additional recessed handles support safe handling when moving the bath between workbenches, shelves and transport carts.<\/p>\n<p>A sealed transport cover helps prevent fluid

bath temperature<\/li>\n<li>Temperature setpoint<\/li>\n<li>Date and time<\/li>\n<li>Temperature control status<\/li>\n<li>Heating status<\/li>\n<li>Stabilization indication<\/li>\n<\/ul>\n<p>The clear display simplifies operation and allows users to monitor the calibration process directly.<\/p>\n<p>This is particularly useful during routine calibration procedures and multi-point temperature measurements.<\/p>\n<h2>Temperature Stabilization Indicator<\/h2>\n<p>The Fluke Calibration 7109A provides a convenient temperature stabilization indicator.<\/p>\n<p>The indicator changes from amber to green when the bath reaches the required stabilization condition.<\/p>\n<p>This provides a clear visual indication that the bath is ready for calibration measurements.<\/p>\n<p>The indicator is visible from different directions, allowing technicians to monitor the instrument without continuously checking the display.<\/p>\n<p>For demanding reference measurements, the stabilization requirements of the calibration procedure must still be observed.<\/p>\n<h2>Hot Surface Warning<\/h2>\n<p>The Fluke Calibration 7109A includes a hot surface warning indicator.<\/p>\n<p>The warning activates when the bath fluid temperature exceeds:<\/p>\n<p><strong>60 \u00b0C<\/strong><\/p>\n<p>This alerts the operator that the bath fluid and surrounding tank area may be hot.<\/p>\n<p>The warning is particularly important when calibrating sensors at elevated temperatures.<\/p>\n<p>Appropriate protective equipment and safe handling procedures must always be used.<\/p>\n<h2>Fast Heating Performance<\/h2>\n<p>The Fluke Calibration 7109A provides efficient heating performance.<\/p>\n<p>The manufacturer specifies the following typical heating times:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Temperature Change<\/th>\n<th>Typical Heating Time<\/th>\n<\/tr>\n<tr>\n<td>\u221225 \u00b0C to +25 \u00b0C<\/td>\n<td>35 minutes<\/td>\n<\/tr>\n<tr>\n<td>+25
