TRUE TEMPERATURE BENCH INDICATOR
Model TTI-2 True Temperature Indicator

TTI-2 True Temperature Indicator
If you need the very finest bridge at the mkelvin accuracy level then the TTI-2 will delight you. 
Here are just some of the reasons why TTI-2 is the preferred instrument in many laboratories.

TTI 2 - 1mK, True Temperature Indicator
True Temperature Indicator
  • Accuracy up to ±0.001°C

  • Resolution up to 0.00001°C on average 
    and standard deviation display

  • 10 thermometer characteristics can be 
    programmed into the TTI-2

  • Proven operation at international level 
    Indicates °C, °F, K or Ratio

  • 2 Thermometer channels plus 1 external 
    reference resistor channel as standard

  • Range -259°C to +962°C

  • Simple to use SPRT/PRT Instrument

  • The display shows the true unfiltered single measurement value, not an artificially filtered value which appears stable only due to filtering and averaging of values.

  • There are no preset type controls such as variable resistors in the design, it is completely solid state. Calibration adjustments are software controlled.

  • There are no mechanical relays, so the TTI-2 has increased life and reliability.

  • Simultaneous display of two channels — essential for high quality comparison calibration.

  • In statistics mode, the TTI-2 resolves and averages up to 50 readings of 2 channels simultaneously and present the mean values (Temperature, Resistance or Ratio) to ±0.00001°C resolution as well as giving the standard deviation of the mean value.

  • The TTI-2 uses a single power source which reduces noise effects considerably.

  • Password protection — prevents unauthorized tampering with the Bridge.

  • The Bridge automatically stops and awaits instruction once the standard thermometer has been either over temperatured, or has passed its recalibration date.

  • With an uncertainty of better than 1mK (0.001°C), this temperature indicator is the best of its kind.

  • Based on its use, one German D.K.D. approved laboratory has obtained a calibration schedule with a total uncertainty of 0.5mK at the triple point of water.

  • The TTI-2 can be programmed with up to 10 thermometer characteristics.

  • If you would like to know more about the TTI-2 we have a video, a comprehensive handbook, and a P.T.B. evaluation.
