Fluke Calibration 9142 [9142-D-P-256] Field Dry-Well Metrology Temperature Calibrator with Model 9142-INSD ("D" Insert) and Process Option, -25 °C to 150 °C

The Fluke Calibration 9142DP256 Field Metrology Well Temperature Calibrator with Model 9142-INSD ("D" Insert) and Process Option, -25 °C to 150 °C is designed to be a reliable, stable heat sources that can be used in the field or laboratory. It offers accuracy, portability, and speed for nearly every field calibration application. The instrument has been designed with the field user in mind and is easy to use while maintaining stability, uniformity, and accuracy comparable to some laboratory instruments.

The Fluke Calibration 9142-D-P-256 has special, built-in features that make it extremely adaptable. The exclusive Voltage Compensation allows the technician to plug into mains power without degradation to the instrument. The Ambient Temperature Compensation provides a large operating range, with an equally large, guaranteed temperature range. The Gradient Temperature Compensation keeps the axial gradient within specification over the entire temperature range of the 9142-D-P-256 and over the specified guaranteed operating temperature range. These combined features, along with the rugged design, light weight, and small size make this instrument ideal for field applications.

The Fluke Calibration 9142-D-P-256 has a unique Air Flow Design that keeps the probe handle cool, while protecting delicate instruments, as well as the user. The Block Temperature Indicator shows the user when the well temperature is above 50°C, letting the user know when it is safe to remove the insert or move the instrument. The indicator light illuminates when the instrument is energized and the well is above 50°C. If the instrument is removed from mains power, the indicator light flashes until the well has cooled to less than 50°C.

[The 9142-D-P-256 "Process" version combines the heat source with a built-in readout, eliminating the need for the technician to take two instruments into the field. The readout is perfect for transmitter loop, comparison calibration, or a simple check of a thermocouple sensor. There is no need to carry additional tools into the field with the 9142-D-P-256's built-in readout for resistance, voltage, and mA measurement, 24V loop power, and on-board documentation. The convenient and smart reference connector automatically transfers and stores the probe coefficients.]

The Fluke Calibration 9142-D-P-256 controller uses a PRT sensor and thermoelectric modules or heaters to achieve stable, uniform temperatures throughout the block.
