The TTI-6 is a high precision portable thermometer for metrology and other exacting laboratory applications, the TTI-6 is a proven instrument used World-wide as a laboratory and site standard. It is particularly suitable as the reference standard for temperature calibration baths.

The TTI-6 Digital Thermometer utilises highly advanced microprocessor circuit design to achieve exceptional measuring accuracy, linearisation conformity and stability in a versatile but easy to use configuration. Based on a high resolution 20 Bit Analogue to Digital convertor, all measurement computations are performed digitally without drift. The 5 LED display provides a readout to 0.01ºC over the entire -199.99ºC to +849.99ºC range; alternatively ºF, Kelvin or Ohms values can be displayed up to 999.99 units.

Single or dual Pt100 3 or 4 wire sensors are accepted, the TTI-6 will automatically recognise and select 3 or 4 wire mode. Display of input A, B or A - B (differential) can be selected; a differential “zero function” allows sensor accuracy differences to be eliminated for accurate differential readings.

Calibrated sensors can have their calibration points programmed into the TTI-6 via a personal computer using Isotech Software. The instrument then digitally self calibrates to the probe(s) providing corrected temperature readout to give optimum system accuracy.

A common application is for the comparison calibration of a sensor on channel B against a reference standard on channel A. With one of the Selector Switches several sensors can easily be compared to a standard probe on A. The instrument includes a UKAS certificate as standard (simulation calibrated). Isotech also offers a complete system calibration (probe and instrument combined).
