Wöhler DT 310 Differential Thermometer

The Wöhler DT 310 is a differential thermometer designed for surface temperature measurement on water and exhaust pipes. It measures temperature at two points and displays the differential value alongside both readings. That operating format supports flow and return surface temperature checks in building and exhaust-related workflows.

- Accepts two probes so two surface temperatures can be measured at the same time.
- Calculates and displays differential temperature when two probes are connected.
- Shows both temperature readings simultaneously for direct point-to-point comparison.
- Supports probe classes K, J, and T for compatible temperature measurement setups.

- Resolution for K probes is 0.1 °F from -200 to 1,200 °F and 1 °F from 1,200 to 2,500 °F.
- Resolution for J probes is 0.1 °F from -200 to 930 °F and 1 °F from 930 to 1,400 °F.
- Resolution for T probes is 0.1 °F across the complete range.
- Accuracy is ±0.3% of measured value + 0.7 °F for K, J, and T within their specified ranges.
- Operates on a 9V block battery in ambient conditions from 0 to 120 °F and 0 to 85% r.H. non-condensing.

- Surface temperature measurement of flow and return lines on water pipes.
- Surface temperature measurement on exhaust pipes.
- Differential temperature checks where two surface points need to be compared.
