This type J thermocouple sensor has an exposed junction tip to get temperature measurements as quickly as possible. This low-cost sensor utilises 7/0.2mm stranded class 1 wires that are welded at the tip to ensure accurate, quick readings. The overall diameter of this sensor is only around 2.5mm which makes this ideal for fitting into tight spaces. The 2 metre long PFA flat pair cable allows the sensor to be immersed within temperatures between -50°C to 250°C while being easy to manage. This lead can be cut down if required without affecting the readings.
