The Hart Scientific 7102 Micro-Bath may be used as a portable instrument or bench
top temperature calibrator for calibrating thermocouple and RTD temper ature probes.
The 7102 is small enough to use in the field, and accurate enough to use in the lab.
With an ambient temperature of 23°C (74°F), calibrations may be done over a range of
–5°C to 126°C (23°F to 259°F). The resolution of the 7102 temperature display is 0.01
degrees.
The Micro-Bath calibrator features:
Convenient handle
●
●
RS-232 interface
●
●
Switchable AC Input (115 VAC or 230 VAC)
●
●
Optional well extender to extend well depth
●
●
Built in programmable features include:
Temperature scan rate control
●
●
Temperature switch hold
●
●
Eight Set-point memory
●
●
Adjustable readout in °C or °F
●

The temperature is accurately controlled by Hart’s hybrid analog/digital con troller. 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 tempera ture
within the specified range. The calibrator’s multiple fault protection de vices insure
user and instrument safety and protection.
The 7102 Micro-Bath was designed for portability, low cost, and ease of opera tion.
Through proper use, the instrument will continuously provide accurate calibration
of temperature sensors and devices. The user should be familiar with the safety
guidelines and operating procedures of the calibrator as de scribed in the instruction
manual.
