Description

The PLB 157 is a ultra low Micro Bath with an operating range from -50ºC to 160 ºC, large calibration volume (45 x 185 mm) and unrivaled flexibility.

As a Micro Bath the PLB 157 is suitable for calibrating any type and odd shaped temperature sensors including mechanical bulb thermometer and UTI

Accessories are available to convert the PLB 157 to a traditional dry block temperature calibrator, surface sensors temperature calibrator and even infrared sensors temperature calibrator.

The PLB 157 is available in two versions- the TS and TC.  The TS  has a digital display for set and nominal temperature, the TC additionally includes inputs for reference sensor and test thermometers
