exceptionally wide temperature range makes the instrument suitable for low-temperature applications that cannot be covered by conventional portable dry-block calibrators.<\/p>\n<p>The temperature range is specified at an ambient temperature of 23 \u00b0C.<\/p>\n<p>Typical calibration temperatures include:<\/p>\n<ul>\n<li>\u221295 \u00b0C<\/li>\n<li>\u221280 \u00b0C<\/li>\n<li>\u221260 \u00b0C<\/li>\n<li>\u221240 \u00b0C<\/li>\n<li>\u221220 \u00b0C<\/li>\n<li>0 \u00b0C<\/li>\n<li>+25 \u00b0C<\/li>\n<li>+50 \u00b0C<\/li>\n<li>+100 \u00b0C<\/li>\n<li>+140 \u00b0C<\/li>\n<\/ul>\n<p>The ability to generate temperatures down to \u221295 \u00b0C is particularly useful for calibration applications in pharmaceutical manufacturing, environmental testing, aerospace and industrial temperature metrology.<\/p>\n<h2>Excellent Temperature Accuracy<\/h2>\n<p>The Fluke Calibration 9190A provides two important accuracy specifications.<\/p>\n<h3>Display Accuracy<\/h3>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.2 \u00b0C across the entire temperature range<\/strong><\/p>\n<p>This specification describes the accuracy of the internal temperature indication under the manufacturer&#8217;s defined operating conditions.<\/p>\n<h3>Accuracy with External Reference<\/h3>\n<p>When a suitable external reference thermometer is used, the manufacturer specifies:<\/p>\n<p><strong>\u00b10.05 \u00b0C across the entire temperature range<\/strong><\/p>\n<p>This allows significantly more accurate comparison calibrations.<\/p>\n<p>The external reference thermometer measures the actual temperature within the calibration insert.<\/p>\n<p>The device under test can then be compared directly with the reference thermometer.<\/p>\n<p>For demanding applications, the uncertainty of the complete calibration system must be evaluated.<\/p>\n<h2>Outstanding Temperature Stability<\/h2>\n<p>The Fluke Calibration 9190A provides excellent temperature stability.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.015 \u00b0C<\/strong><\/p>\n<p>This specification applies across the entire temperature range.<\/p>\n<p>Temperature stability

Loading Effect<\/h2>\n<p>The Fluke Calibration 9190A is designed to minimize temperature changes caused by inserting multiple sensors into the calibration block.<\/p>\n<p>The manufacturer specifies a loading effect of:<\/p>\n<p><strong>\u00b10.006 \u00b0C<\/strong><\/p>\n<p>This value applies under specified conditions with one 6.35 mm reference probe and three additional 6.35 mm probes.<\/p>\n<p>Low loading effects are particularly important when calibrating multiple sensors simultaneously.<\/p>\n<p>The actual loading effect depends on the number, diameter and thermal characteristics of the inserted sensors.<\/p>\n<h2>Deep Calibration Well<\/h2>\n<p>The Fluke Calibration 9190A features a calibration well with a depth of:<\/p>\n<p><strong>160 mm<\/strong><\/p>\n<p>The well diameter is:<\/p>\n<p><strong>30 mm<\/strong><\/p>\n<p>The deep calibration well helps minimize heat conduction errors along the sensor stem.<\/p>\n<p>Sufficient immersion depth is essential for accurate temperature calibration.<\/p>\n<p>The actual required immersion depth depends on sensor geometry, sensing element position and the required measurement uncertainty.<\/p>\n<h2>Interchangeable Calibration Inserts<\/h2>\n<p>The Fluke Calibration 9190A uses interchangeable calibration inserts.<\/p>\n<p>Different insert configurations are available for sensors with various diameters.<\/p>\n<p>Available configurations include:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Insert<\/th>\n<th>Configuration<\/th>\n<\/tr>\n<tr>\n<td>9190-INSA<\/td>\n<td>Mixed
