NPH pH/ORP Node

pH,ORP,Node,Model NpH,Lakewood InstrumentsThe 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.

The NpH can be used with OSMONICS® Lakewood 2000 Series Controllers. It can be used on cooling towers, boilers, wastewater, reverse osmosis and other processes.

One Network Interface Node (NIN) per 2000 Series Controller is required to operate network nodes such as the NpH.
