Tempcal H

Designed to provide a stable and accurate environment for the calibration of temperature sensors - including liquid-in-glass & dial thermometers, thermocouples, RTD's, thermal switches, transmitters and fluid filled bulbs.

The Tempcal H Dry Block Calibrators come in three temperature ranges covering from -40ºC to 650ºC 


  • High accuracy and stability
  • Large interchangeable multiple drilled insert
  • Unique temperature zone - with improved uniformity and control stability
  • Rapid heat-up and cool-down times
  • TempWorks calibration software
  • RS232 interface for data and program transfer, or real time control
  • Fast settling time for rapid testing
  • 4 line 20 character LCD display with an 8 button keypad for entering programs and viewing data
  • Ability to create / use / store programs and test results internally
  • Programming of set temperature, ramp rate, hold time, “pause on switch change-over” operation and hold until pause pressed
  • Switch test input for monitoring temperature thermostats
  • Calibration using the User Probe Interface which allows storage of the block temperature and the reading of the test sensor

TempWorks Software has been designed for use with the Tempcal H and many other products from Haven's range of temperature equipment. It is a Windows® based program that connects via an RS-232 connection to your computer. Programs can be created, saved and re-called at any time as well as running in real time mode.

With TempWorks running on a PC you can set and read the dry block temperature, create and run temperature cycles with multiple set points, and control the rate of change.  You can also use external thermometers such as Spec-Cal Eclipse II, Accu-Temp, Accu-Temp II, Cropico 3000 series and
ASL F250.

Also available is the 'F' version which is designed for field use, so is more compact and lightweight
