- SNAP-pH/ORP Differential Voltage Measurement Input Module
The SNAP-pH/ORP module provides two isolated channels of high-impedence voltage input, either -1.00 to +1.00 volts or -0.50 to +0.50 volts. The module is ideal for differential voltage measurements and is used with pH or oxidation reduction potential (ORP) probes for monitoring bodies of water.
The SNAP-pH/ORP module can be used with SNAP PAC brains and R-series controllers, legacy SNAP Ethernet-based brains, and legacy serial B3000 and B3000-B brains.
