Dry block calibrator HTR-400

high temperaturetemperaturelaboratory

Overview
Dry-block (dry well) calibrator for extended high-temperature range. The Kaye HTR-400 is designed for the calibration and verification of temperature sensors. The dry well uses specialized inserts that minimize cooling of thermocouple tips caused by heat conduction.

Features

• Dry-block design suitable for high-temperature range calibration
• Specialized inserts reduce cooling of thermocouple tips by heat conduction
• Intended for calibration and verification of temperature sensors (thermocouples and resistance sensors)

Notes
Kaye has offered the HTR-400 for over 25 years. The manufacturer describes this model as a legacy unit with outdated technology and limited availability of ongoing parts and service. A newer replacement model, the HTR-420, is available with expanded functionality (increased sensor capacity, efficiency and performance).
