Introduction
The Fluke Calibration 7102 Micro-Bath (the Product, calibrator, or instrument) is a portable instrument/
bench-top temperature calibrator. Use the Product to calibrate thermocouple and RTD temperature
probes. The Product 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), calibrate over a range of −5 °C to 125 °C (23 °F to 257 °F). The
resolution of the display is 0.01 degrees.
The Product features:
• Convenient handle
• RS-232 interface
• Universal 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 a 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 (display) continuously shows the current well temperature. Set the temperature
with the control keys to any desired temperature within the specified range. Multiple fault protection
devices ensure user and Product safety and protection.
Through proper use, the Product continuously provides accurate calibration of temperature sensors
and devices.
