Portable 2-channel Thermometer For Resistive Probes And Thermocouples, -200°C To 850°C – AOIP TTI 10


  • High accuracy handheld thermometer: 0.01°C
  • High resolution: 0.001°C
  • Perfect standard for use with industrial baths and dry blocks and Fast-Cal models

The TTI 10 is a high accuracy handheld temperature indicator with two platinum resistance thermometer inputs. The high precision makes the instrument particularly suitable as a portable reference thermometer to use alongside temperature calibrators such as industrial baths and dry blocks and Fast-Cal models. It is also suited for high accuracy measurements in industrial and scientific applications. TTI 10 brings laboratory level performance of up to 10 mK (0.01°C) and resolution up to 0.001°C in a portable handheld instrument. Battery life is typically 20 hours from a 9 V PP3 battery and a protective rubber boot offers protection in field use. The instrument can capture the minimum, maximum and average values over up to 4,000 measurements with a logging rate selectable in the range of 1 s to 30 min.

The TTI 10 has an easy to use “learning calibration mode” that allows it to be system calibrated with a Platinum resistance thermometer simply by comparing it to a calibrated standard thermometer, no need to calculate coefficients or data, simply enter the reference probe temperature or temperatures and the TTI 10 will do the work. A USB interface allows connection to Cal Notepad software with its charting and logging features. TTI 10 supports semi standard platinum resistance probes with system uncertainties (probe and instrument) as low as 20 mK. We recommend the 935-14-61 and 935-14-16 probes detailed below and have special calibration deals available. Other probes and ranges are available, please consult our section dedicated to temperature probes for further details.
