Hart Scientific manufactures these Micro-Baths for calibration of thermometers and sensors that do not fit in block calibrators.


  • Rugged, compact advanced insulation resistance tester for electrical contractors and industrial and commercial electricians
  • Automatically calculates Polarization Index and Dielectric Absorption Ratio
  • Makes repetitive tests simple and easy with a Compare (Pass/Fail) function
  • Offers multiple insulation test voltages: 50 V, 100 V, 250 V, 500 V, and 1000 V


Double your productivity or cut your calibration time in half
  • Temperatures from –15 °C to 350 °C in one unit
  • Two wells in each block for simultaneous comparison calibrations
  • Rugged, lightweight, water-resistant enclosure
You’ve been asking for it and now we’re making it for you. Hart’s new Model 9009 Industrial Dual-Block Calibrator lets you calibrate at hot and cold temperatures at the same time. Double your productivity or cut your calibration time in half—either way you look at it, your in-field temperature calibrations just got easier.


The 4180 Series of Precision Infrared Calibrators for infrared thermometers and thermal imagers is fast, accurate, and easy to use. It comes with an accredited calibration from one of the world’s most trusted temperature calibration laboratories, sample calibration procedures for Fluke thermometers built right in and everything you need to get started making high-quality infrared thermometer calibrations. This is the perfect solution for any infrared thermometer or thermal imager within its temperature range.
The 4180 reaches temperatures from –15 °C to 120 °C and the 4181 has a temperature range from 35 °C to 500 °C. Uniformity is important in infrared temperature calibration work because an infrared thermometer will “see” as much as the entire target when placed at the appropriate calibration distance.
In addition, with accuracies as good as ±0.35 °C the 4180 Series can meet its specifications without additional emissivity-related corrections, leading to legitimate test uncertainty ratios (TUR) as good as 4:1.
