K-type handheld surface thermocouple probes are mainly used to measure the temperature range, especially suitable for industrial applications, to measure the surface temperature of various metal materials. Telescopic wire length: 1.; probe diameter: 15mm; temperature range: -50~500, model: -81532B. The probe is made of stainless steel, which is not easy to rust and can withstand high temperature and corrosion. High precision, used to measure surface temperature, fast temperature measurement. and easy to carry. Durable retractable spring wire is not easy to break. Connect the plug to the temperature display instrument, insert the measuring end into the liquid and gas or make close contact with the solid surface. In order to reduce measurement errors, the thermocouple should have sufficient insertion depth. Color: Black & Silver & Yellow Material: Stainless steel + bakelite Package Contents: 1 x K Type Surface Thermocouple Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
