Additel ADT875-350-C-110V Dry Well Calibrator, 33 to 350 °C
Additel ADT875-350-C-110V Dry Well Calibrator, 33 to 350 °C
Additel ADT875-350-C-110V Dry Well Calibrator
Overview
The Additel 875 Series dry well calibrators combine metrology-level stability, radial and axial uniformity and low loading effect with the speed and ruggedness needed for field work. The ADT875-350 model covers 33 °C to 350 °C and heats across its full range in about 5 minutes.
Dual-zone control keeps the well uniform along its 150 mm immersion depth, a self-calibration function can recalibrate the internal control sensor against an external reference, and set-point control can follow an external reference PRT. The ADT875-350-C-110V is the standard (non-process-calibrator) version supplied for 110 V power with insert C.
Features
- Temperature range 33 °C to 350 °C
- Display accuracy ±0.2 °C; stability ±0.02 °C (30 min)
- Dual-zone control for axial uniformity
- Self-calibration of the internal control sensor with an external reference
- Set-point control by reference PRT
- Choose-your-own-range (CYOR) option; ISO 17025-accredited calibration with data
- 6.5-inch color touch screen; USB, LAN, Wi-Fi and Bluetooth
Applications
- Calibration of RTDs, thermocouples and temperature transmitters
- Verification of temperature switches and thermometers
- On-site calibration in process plants and calibration laboratories
