Additel ADT221A


Multifunction Temperature Calibrator



The Additel ADT221A Multifunction Temperature Calibrator features several patented technologies. It is an ultracompact, rugged, and easy to use device with a smartphone-like menu and interface to make its operation simple.

The Additel ADT221A is very unique to the multifunction temperature calibrator market. Not only does it provide you with the ability to source, simulate and measure temperature and electrical functions but it also incorporates full documenting capability and many other solutions other products do not provide. As a standalone device, you can create tasks, run tests and store the results. With the use of Additel/Land Software or Additel/Cal software, all saved tasks and data can be downloaded and managed. With it's unique internal cold junction compensation sensor, cold junction compensation is very simple and easy.

Product Features:

  • Sources and measures mV, mA, ohms, RTDs, thermocouples, frequency, and pulses
  • Simulates and measures 13 thermocouples and 11 RTDs to calibrate transmitters
  • 24V loop power supply
  • Simultaneous dual reading capability
  • Automatic switch test
  • Supports square root transmitter
  • Pulse frequency output for calibration of flow totalizer
  • Smartphone-like menu and interface make operation simpler and easier
  • Ultra-compact, size 3.9 in. x 7.6 in. x 2.0 in. (100mm x 192mm x 52mm)
  • Weight 1.6 lb (0.7 kg)
  • One hand operation
  • Cold junction equivalent block in calibrator
  • A calibrated PRT element with flexible leads is installed in equivalent block for thermocouple cold junction compensation
  • This PRT element can be pulled out from calibrator and re-calibrated and corrected at ice point by users
  • ISO17025 Accredited Calibration with data
  • Up to 30V voltage on any two sockets and up to 1A current on current sockets will not damage calibrator
  • Calibrator will return to normal condition as soon as voltage or current is removed
  • Rechargeable Li-ion battery for 15 hours uninterrupted use
  • Battery life will be reduced when 24V is applied
  • Rechargeable battery is replaceable
  • Manage information of device under test
  • Set up automated calibration procedures
  • As-found and As-left functions allow recording and documenting results for quality control
  • Download tasks and upload results
  • Snapshots allow you to capture and save work
  • CVD coefficients of calibrated PRT can be input into calibrator for accurate temperature measurement
  • Build-in converters for pressure units, temperature units, temperature vs. resistance (RTDs), and temperature vs. millivolt (thermocouples)
  • 3.5 inch TFT color screen
  • 3 year Warranty
