Efficient cooling technology

The PTC-125 with both heating and cooling capabilities features the FPSC (Free piston stirling cooler) as the cooling source. This is much more efficient than thermo-electric (Peltier) coolers.

High accuracy

Down to ±0.06°C (±0.11°F) using the external reference sensor. 4-wire True-Ohm-Measurement technology applied

Excellent stability 0.01°C

Improved temperature homogeneity

The unique active dual-zone block ensures good temperature homogeneity in the calibration zone

Intelligent reference sensors

JOFRA reference sensors are supplied with intelligent plugs, containing calibration data (coefficients) of the reference sensor. A truly plug’n’play calibration system

USB communication

All PTC calibrators communicate via an easy-to-use USB port

Time-saving

High-speed heating and cooling times. 350°C in only 7 minutes

Work order functionality

Upload advanced calibration routines to your PTC for troublefree and automatic on-site calibrations
