Fluke Hart Scientific 9140

The Fluke Calibration 9140A156 Field Dry-Well Temperature Calibrator with Model 3140-2 ("A" Insert), 35 °C to 350 °C may be used as a portable instrument or bench top temperature calibrator for calibrating thermocouple and RTD temperature probes. The 9140-A-156 is small enough to use in the field, and accurate enough to use in the lab.

The temperature is accurately controlled by Hart's hybrid analog/digital controller. The controller uses a precision platinum RTD as a sensor and controls the well temperature with a solid state relay (triac) driven heater.

The LED front panel continuously shows the current well temperature. The temperature may be easily set with the control buttons to any desired temperature within the specified range. The instrument's multiple fault protection devices insure user and instrument safety and protection.

The 9140-A-156 dry-well calibrator was designed for portability, low cost, and ease of operation. Through proper use the instrument will provide continued accurate calibration of temperature sensors and devices. The user should be familiar with the safety guidelines and operating procedures of the calibrator as described in the instruction manual.
