  • Features and Benefits
  • Specifications

The PTC-125 from the AMETEK Jofra Professional Temperature Calibrator series has a wide temperature range that makes it suitable for a range of applications.

Applications

  • Health Care
  • Medical industry
  • pharmaceutical manufacturing
  • Biotechnology
  • Food and beverage processing
  • Wide temperature range - From -90 to 125°C (-130 to 257°F)
  • High accuracy - Down to ±0.07°C (±0.013°F) using the external reference sensor. 4-wire True-Ohm- Measurement technology is used
  • Most stable cooler calibration on the market - ±0.03˚C (±0.054°F)
  • Fastest calibration possible - The efficient free piston stirling cooler (FPSC) technology is used to secure fast cooling and heating temperature changes
  • Easy to carry - Weighing only 15.2 kg (33.5 lb), the PTC-125 is by far the lightest and most portable cooler on the market
  • Intelligent reference sensor communication - AMETEK Jofra reference sensors are supplied with intelligent plugs, holding the calibration data (coefficients) of the reference sensor. This is a truly plug & play calibration system
  • USB connector for communication - All PTC calibrators communicate via an easy-to-use USB port
