OMEGA’s new wireless pH/temperature transmitter features a high performance microprocessor based wireless radio transmitter built into a NEMA enclosure. Compatible with most pH probes with a BNC connector, the UWPH provides fast, accurate readings. For automatic temperature compensation, the UWPH accepts a Pt100 RTD probe through a standard (series T) connector. Configured through a standard USB port, the UWPH can transmit data at rates from 1 to 30 samples per minute. Each transmitted reading includes the pH and temperature data, along with RF signal strength and battery condition to the host. Using the standard software (included), this data can be displayed on screen in real time. The software allows the user to use your PC as a meter, chart recorder or data logger, so data can be saved, or exported to a spreadsheet file.

Note: pH and RTD probes sold separately. To use without an RTD probe, a 110 ohm resistor must be connected to the RTD input. This will set the temperature input to a fixed value (about 26ºC).

Note: Because of transmission frequency regulations, these products may only be used in the United States, Canada and Europe(please note CE compliance of the specific model for use in Europe).
