TPI 343 Kit 1 Flow & Return Temp Kit

The TPI 343 Flow and Return Digital Thermometer Kit features a TPI 343 Dual Input Type K Thermometer in addition to useful probes for measuring both air and surface temperature.

The TPI 343 thermometer can measure temperature between -50˚C and 1350˚C depending on the probe type and can calculate temperature differential thanks to its dual input. Readings are displayed on a backlit digital display and further useful features include on-site auto-calibration, min/max recording, data hold and digital filter.

Two GK11M air probes allow the user to measure air temperature between -40˚C and 510˚C but can also be easily used for non-food liquids and solid surfaces. The 1.2m lead length means that it is easy to manoeuvre and it boasts fibreglass insulation.

Flow and return temperatures on gas systems can be measured using the kit’s two supplied CK21M pipe clamp temperature probes. With a maximum clamping diameter of 30mm, these probes can be used to measure pipe surface temperature between -50˚C and 250˚C.

Everything comes supplied in a handy soft carry case and a three-year warranty covers all the components of this handy flow and return kit.
