Isotech TTI-10 High Accuracy Thermometer

Fits field and lab PRT work that needs a handheld platinum-resistance thermometer indicator with laboratory-level performance to about 10 mK and 0.001 °C resolution.

Key advantages

~10 mK instrument class — Laboratory-level PRT indication; system uncertainties as low as ~20 mK with recommended probes.
0.001 °C resolution — Fine readout for calibration and comparison work.
Dual Lemo PRT inputs — Two platinum resistance thermometer channels with latching metal Lemo connectors.
Learning calibration + USB — System calibration against a reference without manual coefficients; Cal Notepad via USB.

Typical applications

Field and lab PRT indication needing near-laboratory accuracy.
Dual-channel probe comparison and min/max/average logging.
Routes that download charts via Isotech Cal Notepad.

Selection guide

Indicating range — Typically −200 to 850 °C with suitable PRT probes.
Accuracy — About 10 mK (0.01 °C); system uncertainties as low as about 20 mK with recommended probes.
Resolution — To 0.001 °C.
Inputs — Two PRT inputs; latching metal Lemo connectors.
Logging — Min/max/average over up to 4000 measurements; interval 1 s to 30 min.
Power — About 20 hours from 9 V PP3; protective rubber boot.
Interface — USB; Isotech Cal Notepad.

Common mistakes

Quoting indicator accuracy as system accuracy without the probe — ~10 mK instrument vs ~20 mK system with recommended probes.
Ordering without confirming Lemo PRT probe compatibility and range (−200…850 °C typical).
Skipping Cal Notepad / USB need when route logging and charting are required.
Ignoring battery/boot field packaging when the duty is benchtop-only (or the reverse).

When to RFQ / what to tell us

PRT probe type/range and whether dual-channel comparison is required.
Target system uncertainty and need for learning calibration mode.
Cal Notepad/USB logging needs, quantity, ship-to country.
