Dry-BlockTemperature Calibrators
NEW State-of-the-art 
dry-block temperature
calibrators 
The JOFRA ATC series is a complete test laboratory to take out to the process line:
  • Specially designed to fulfil the EA-guidelines
  • Dual-zone heating block
  • The homogeneity in the lower zone of the block is close to that of a laboratory bath. The upper zone compensates for heat loss from the sensor-under-test and from the top of the block
  • Many features such as: Built-in reference thermometer for use with an angled external reference sensor to allow room for the sensor-under-test with transmitter head, top connector, etc. - Internal and external reference sensors are independant of each other - Automatic calibrations for thermostats, resistance thermometers, thermocouples, transmitters, milliamps, and voltage. - Software AMECAL-TEMPERATURE to customize calibration routines and to verify measurement results, downloading of calibration tasks.............

compac-low-fa.jpg (16429 bytes) True, fast and easy calibration with the Compact series from JOFRA INSTRUMENTS:
  • All models are delivered ready for use in alu carrying case. All necessary accessories included 
  • Calibration certificate, traceable to International Standards
  • Many built-in facilities, such as: Fully automatic switch test and hysteresis test, leaving the user free to concentrate on other things while the test is running Automatic change from temperature to temperature. This allows the calibrator to be placed anywhere in the process while the user monitors the output from the sensor in the control room — Large LCD display with stability indicator — Specially designed heating block for fast and stable temperature calibrations — Built-in adjustment / calibration routine for the calibrator itself
  • Model C-320-2 and model C-650-2 for applications requiring extra long insertion depth
  • All models are conforming to CE-regulations
