PTC 125 Ref Temp Calibrator

AMETEK continues to develop new techniques to improve performance, accuracy,

convenience and functionality of the well-known JOFRA calibration products.

By doing so, Ametek maintains their position as the leading worldwide manufacturers of temperature dry-block calibrators.

The PTC calibrator comes in three different models:

• Model A - basic model, without input

• Model B - full model, with DLC sensor input and input for reference sensor and sensor-under-test

• Model C - middel model with DLC sensor input and input for reference sensor

The PTC offers many of the weel-known JOFRA features, such as:

• Easy-to-read color VGA display with perfect overview of the actual calibration status

• Intelligent recalibration information, IRI

• Intuitive, fast and user-friendly navigation

• Lightweight and easy to carry around

• Functional carrying case

• Multi-hole insert kits covering all the most used sensor sizes

• High profile design and the well-known long lasting JOFRA quality

NEW!! Efficient cooling technology

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

High accuracy

Down to ±0.06°C (±0.11°F) using the exter-nal reference sensor.

4-wire True-Ohm-Measurement technology applied

Excellent stability 0.01°C

Wide temperature range

PTC-125 from -90 to 125°C (-130 to 257°F)

Improved temperature homogeneity

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
