Fluke 7103-TR-156 Calibration Bath

Overview

The Fluke 7103-TR-156 is a portable bench-top temperature calibrator designed for calibrating thermocouple and RTD temperature probes. It features a compact design with a 64 mm (2.5-inch) diameter, 140 mm (5.5-inch) deep tank, making it small enough for field use while maintaining laboratory accuracy. The instrument achieves temperature stability of ±0.03°C at -25°C and ±0.05°C at 125°C, with excellent uniformity suitable for liquid-in-glass and bimetal thermometers.

The Fluke 7103-TR-156 uses a fluid-based design rather than a dry-well approach, maximized for true fluid-bath performance. The compressor-free design with only one moving part ensures durability and minimizes weight, making it easy to transport without carts. The bath can calibrate any type of sensor including short, square, or odd-shaped sensors due to the fluid medium that eliminates immersion and fit problems.
