This is a brand new, high quality digital thermometer DM6802 for contact temperature measurements. It has two inputs for K-type thermocouples and can display T1 or T2 or the differential temperature T1-T2.

It can be used in HVAC trade to check air conditioners, heaters or furnaces. It  allows you to measure an inlet and an outlet temperature and the difference of both. 

It is also great for science fair projects and whenever you need a precise measurement of two temperatures.

It comes with two 3 ft (1 m) temperature probes, they have a glass fiber insulation and work up to about 500°F (260°C) , but any other K-type probe with miniature thermocouple connector can be used. To use the thermometer for temperatures above 500 degree you would need a special thermocouple with a ceramic insulation (not included), or an insertion probe. Please check my shop for a good selection.

    Better than expected

    Posted by Eric on 3rd Feb 2015

    I am very happy with my purchase of the DM6802 digital thermometer. This instrument is better quality than you would expect at this price. The display is large and easy to read, and the buttons are easy to operate. Works well out of the box with the included thermocouples, but I am currently using it with a third party liquid-tight thermocouple.
