ZRP31 is capable of detecting pressures as low as 0.05 inches of water. Factory calibrated units maintain set point tolerance of +/- 10% over a temperature range of -40°F to 185°F due to its molded silicone diaphragm and stability of its glass filled polyester body. We offers multiple electrical terminations and mounting options as well as bleed holes and 3 different size orifices.
