Additel 875 Dry Well Calibrator

If you are serious about portable temperature calibration, you know that a high-quality dry well must be more than just a stable heat source. The Additel 875 Series combines excellent performance in stability, radial and axial uniformity, and speed with rugged durability and portability.

Key Features:

• Portable, Rugged, and Quick to Temperature: Designed for field use with fast heating and cooling times.
• Metrology-Level Performance: Superior performance in stability, uniformity, accuracy, and minimizing Loading Effects.
• Dual-Zone Control: Utilizes a two-zone heating system to ensure significantly better thermal uniformity across the block.
• Color Touchscreen Display: Features a vibrant, intuitive touch interface for easy navigation.
• Choose Your Own Range (CYOR): A unique option to define and optimize the calibrator’s accuracy for your specific working range.
• ISO 17025-Accredited Calibration: Every unit includes an accredited calibration certificate with full measurement data.

Advanced Functionality:

• Process Calibrator (PC) Option: This option turns the dry well into a complete workstation, providing a multi-channel readout for reference thermometers, RTDs, and TCs. It also handles task documentation and full HART Communication.
• Full HART Field Communicator: Allows for the communication, configuration, and maintenance of HART-enabled transmitters directly from the calibrator.
• Set Point Control by Reference: Allows the calibrator to control and stabilize its temperature based on the reading of an external reference probe rather than the internal sensor.
• Self-Calibration Feature: An innovative function that uses an external reference PRT to automatically re-align the internal sensor’s calibration, ensuring long-term accuracy.

Specifications:

• Temperature Range: -40°C to 660°C (depending on model)
