PR540 Ice-Point Reference Dry-Well

PR540 Series Ice-Point Reference Dry-Well is an excellent fixed-point temperature device. It can provide a stable and precise reference junction thermostatic environment for extended periods during the verification and calibration of noble or base metal thermocouples. As an ideal replacement for traditional ice point devices, it is the preferred equipment for conducting thermocouple verification and calibration work.

I. Product Feartures 

• Excellent temperature stability

Maintains a consistent 0°C environment for extended periods, impervious to external environmental fluctuations. The built-in temperature control system of the PR540 Series exhibits an annual variation of less than 0.03°C and features an ambient temperature compensation algorithm for real-time correction of the working cavity temperature.

• Rapid cooling

Achieves a peak cooling rate of 6°C/minute, stabilizing to the verification-required 0°C point in just 15 minutes from room temperature.

• Insulated Jacks

Model B feature 0.5mm-thick insulation layers on the inner walls and bottoms of the jacks, enabling direct insertion of bare metal wires without additional insulation measures. 

• Manual Adjustment of Temperature Correction Values is Supported.

The temperature correction values can be manually adjusted via mechanical buttons.
