1、THREE LAYERS OF PTFE: Our temperature sensor probe adopts three layers of PTFE protection, the first layer is acid and alkali resistant PTFE, the second is white PTFE insulation, the third layer of 3 PTFE material high temperature wires (one white and two red). 2、BETTER WATERPROOF: Our Pt thermistor temperature sensor probe is more resistant to acid and alkali, better waterproof effect. 3、MAXIMUM RESISTANCE TO 200°C: The Pt thermistor temperature sensor probe is integrated with the wire, waterproof. It can withstand up to 200℃ high temperature (180℃ for long term use). 4、STAINLESS STEEL PROBE: Temperature sensor probe high sensitivity, high accuracy, the use of stainless steel probe, practical and sturdy. 5、USES: Temperature sensor probe for electroplating, petroleum, chemical, and other industries in corrosive water temperature measurement. Is a common temperature measurement tool in the acid and alkali industry.
