TP31-S - Folding Thermometer - Fast And Reliable Core Temperature Measurements

The TP31-S indicates temperatures quickly and reliably from within fluids and penetrable materials (core temperatures). The simple operation ensures an efficient measurement.

The rugged immersion probe can be folded out to an angle of 180°, and thanks to its robust hinge, can penetrate semi-solid and viscous plastic materials under considerable force.

Thanks to the IP65 protection, the TP31-S can be cleaned easily under running water.
