Features
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.
