The Isotech TTI-22 true temperature indicator has an accuracy of 0.001°C and a resolution of 0.0001°C (0.00004 Ohms). It has two input channels, is lightweight (4 lbs) 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 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.
The TTI-22 continually compares the connected sensor to a highly stable precision internal reference resistor. For a Pt100 at 0°C the annual stability for absolute measurement is typically ±1.3mK (5ppm x 100Ω = 0.5mΩ / 1.3mK).
The TTI-22 includes Cal Notepad software for easy monitoring and logging of data. It is fully compatible with Isotech I-CAL Easy, which can automate comparison calibration.
