The pH/ORP Node (NpH) is a LONWORKS® Technology-compatible node that uses twisted pair communications. The NpH can be used to monitor pH or ORP. The NpH contains Lakewood's unique differential input circuitry for accurate pH and ORP readings. With seven different temperature compensator inputs and its differential input circuitry the NpH can be used with other manufactures pH/ORP electrodes. Temperature compensation is adjustable by percent per degrees Celsius for use with various processes. In addition to its unique design it also contains sensor diagnostics sending an alarm to the user when a probe problem occurs.
