ORP/pH Sensor Connects Directly to Interface Boards. Able to connect to analog input on PhidgetInterface board, 1130 is completely plug-and-play and can be programmed via API supported under Windows, Mac, and Linux. Users can connect pH or ORP glass electrodes via adapter's BNC connector, and on-board DIP switch allows selection of pH or ORP mode of operation. While pH input range is -400 to +400 mV with resolution of 1 pH/54.4 SensorValue, ORP input range is -2,000 to 2,000 mV with resolution of 100 mV/20 SensorValue ...
