AMETEK continues to develop new techniques to improve performance, accuracy, convenience and functionality of the well-known JOFRA calibration products. By doing so, we maintain our 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!! Efficiant cooloing technology
The PTC-125 with both heating and cooling capabilities features the FPSC (Free piston stirling cooler) as the cooling sourceIt 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)
PTC-155 from -25 to 155°C (-22 to 311°F)
PTC-350 from 33 to 350°C (91 to 662°F)
PTC-660 from 33 to 660°C (91 to 1220°F)
Improved temperature homogeneity
Unique active dual-zone block ensures good temperature homogeneity in the calibration zone
