Quite simply, the Isotech TTI-22 High Accuracy Thermometer sets new standards in the price-to-performance ratio for industrial and secondary resistance thermometry. If you need high accuracy from a reference standard at an affordable price, you have to look at the TTI-22.

The TTI-22 has an accuracy of 0.001°C and a resolution of 0.0001°C (0.00004 Ohms). This high accuracy thermometer has two input channels, is lightweight (1.8kg), and will operate for more than 10 hours from two small AA cells. It has both RS232 and Ethernet ports.

Simple to use, supporting both Industrial 100 Ohm probes and SPRTs to ITS-90, 25.5 and 100 Ohm. Up to 30 probe calibrations can be stored, along with the calibration expiry date, so the instrument can warn when the calibration time has been exceeded.

Built-in statistics calculation can show you both the measured and average values, along with the standard deviation over previous measurements.

The Isotech TTI-22 is ideal as a reference standard alongside liquid calibration baths, for the smallest uncertainty calibration with Dry Blocks, or for demanding stand-alone measurement applications.

Previously, this level of performance was confined to specialist laboratories with expensive thermometry bridges; TTI-22 delivers 5 to 10 times the performance of comparably priced instruments.
