Product Details
Panran Calibration's new liquid thermostat Bath series features four models covering temperatures from –80 °C to 300 °C. Find high temperature baths (300 °C) and refrigerated baths for low temperature calibration (–80 °C), in compact packages, and with deep immersion from Panran Calibration our metrology baths are well known world-wide for excellent temperature control that maintains excellent temperature stability (±0.005 °C) and uniformity (±0.007 °C).
Each model includes a 480 mm deep tank to accommodate long-stem PRTs, SPRTs, and liquid-in-glass (LIG) thermometers. Access openings are 100 by 130 mm , so you can calibrate many thermometers simultaneously. Yet only 18~23 liters of fluid are needed to get all the benefits liquid thermostat baths offer.

Using our own best-in-class temperature controller, these baths deliver the performance you need for confidence in your calibrations. The PR512-300 (90 °C to 300 °C) features both stability and uniformity better than ±0.007 °C over its entire range. ThePR532 (–80 °C to 95°C respectively) are stable to ±0.01°C and uniform to ±0.01 °C at temperatures below ambient.And finally, the PR522 provides stability and uniformity from ±0.007 °C to ±0.01 °C over its range from 10°C to 95°C.
1.480mm (18 in) of depth with just 23liters (4.2 gal) of fluid
2.Perfect for liquid-in-glass thermometers with optional LIG kit
3.Fast, quiet, compact (yet deep!), and economical
Used in thermal resistance, glass liquid thermometer, pressure thermometer, bimetallic thermometer, low temperature thermocouple measuring and calibration
Like all Panran Calibration baths, these units come with a report of test that includes one hour of stability data and a verification of set-point accuracy. A convenient overflow reservoir captures any excess fluid resulting from fluid expansion, allowing the trapped fluid to be reused following subsequent fluid contraction. A drain is also provided for easily emptying the bath’s tank when needed.
