Product Introduction
SPK21 12v 24v Negative Low Air Conditioner Pressure Sensitive Controller Switch adopts all-stainless steel structure. The pressure sensing components are automatically tested by computer. The laser calibration process compensates the zero point and temperature performance over a wide temperature range, which enhances the long-term stability of the transmitter in industrial environments. It adopts laser welding technology, safe and leak-free.
