Temperature calibrator HTR-420

dry blockhigh temperaturefor ovens

Description
The Kaye HTR-420 high-temperature dry block calibrator provides precision calibration for industrial and laboratory thermal validation up to 420°C. It supports simultaneous calibration of up to 48 thermocouples using a dedicated 48-TC fixture that ensures secure full immersion. The unit integrates with Kaye software (Validator 2000, Validator AVS, ValProbe, RF ValProbe) for automated or manual procedures and can be operated standalone via a 7" color touchscreen.

Key features

• Operating range: 30°C to 420°C; stability ±0.010°C; uniformity 0.1°C
• Fast heating and cooling performance
• Simultaneous calibration for up to 48 thermocouples with dedicated dry block inserts
• Inserts compatible with thermocouples, IRTD, ValProbe flexible/bendable and RF ValProbe probes
• Software interface for Kaye products (Validator 2000, Validator AVS, ValProbe, RF ValProbe) for automatic/manual calibrations
• 7" color touchscreen for local control
• Universal power supply 100–240 VAC, 50/60 Hz
• Optional inserts available for specialty or process probes

Applications
Designed for laboratories and industrial thermal validation tasks that require high-temperature calibration capacity and repeatable results. Typical uses include calibration of sensors for autoclaves, sterilizers, ovens, hot-air tunnels, fermenters and other high-temperature process equipment.
