Martindale DT173 Digital Thermometer (K-type)

What is the Martindale DT173 K-Type Digital Thermometer?

The Martindale DT173 is a single-input K-Type digital thermometer designed for UK HVAC engineers and building services technicians who need accurate contact temperature measurements across a wide range of applications. With a measurement range from -200 °C to 1372 °C, it is ideal for testing air temperatures, pipework, plant equipment and electrical components during commissioning, servicing and fault-finding.

Supplied with a bead thermocouple and housed in a protective holster, the DT173 delivers clear readings via its large backlit display, even in low-light plant rooms and site environments. An adjustable offset function allows users to optimise probe accuracy over the required temperature range, helping improve confidence in critical measurements.

How does the DT173 support everyday HVAC diagnostics?

The DT173 includes MIN / MAX / AVG recording, making it easy to capture temperature fluctuations over time when checking system performance or investigating intermittent faults. A fold-out stand provides a stable viewing angle during longer tests, while auto power-off is disabled in recording mode to support extended monitoring without interruption.

Compatible with a wide range of Martindale K-Type probes including air, penetration, surface and clamp probes, the DT173 adapts easily to different HVAC and electrical testing tasks without the need for multiple instruments.
