chevron_right
Quite simply the Isotech TTI-22 High Accuracy Thermometer sets new standards in the price to performance ratio for industrial and secondary resistance thermometry.
- Accuracy of 0.001°C and a resolution of 0.0001°C (0.00004 Ohms)
- A reference thermometer for your PRT or SPRT Standards
- For use in the lab or to achieve the highest accuracy in the field
