Provide fast replacement and calibration services for sensors, with the replaced ceramic sensors traceable to NPL and NIST measurement standards. The calibration data of the sensor is stored in the fixed memory of the circuit board at the factory, and does not require users to configure or input data again. This replacement only requires the shortest downtime to maintain calibration, which is more professional, planned, and economical for the user's quality assurance system compared to traditional factory verification. The Easew PRO I. S humidity sensor is very sturdy and durable, combining chemically inert materials with physical toughness to provide process measurement with a maximum pressure resistance of 40MPa. The sturdy structure prevents the sensor from being affected by the flow of dense liquids and pressure shocks caused by sudden pressure changes during driving and maintenance. The measurement is also not affected by liquids generated during ethylene glycol and other process treatments, and can withstand the corrosion of hydrogen sulfide, mercaptan, and other sulfides.
