New Scientific Thermometer  Nicety® DT804A

Two K-Type Sensors

Measures -58.0 to 2372.9 °F (-50.0 to 1300.0 °C)

New and improved version, displays with 0.1 degree precision!

New, now displays °F, °C and K (Kelvin) - great for scientific measurements.

This is a brand new, high quality k-type thermometer for contact temperature measurements. It has two inputs for K-type thermocouples and can display T1 or T2. It also allows to display the differential temperature T1-T2 in degree Celsius, degree Fahrenheit and Kelvin.

It can be used in HVAC trade to check air conditioners, heaters or furnaces. It conveniently allows to measure an inlet and an outlet temperature. 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 one of the stainless steel probes I offer (see table below for a good selection).
