OM-CP-RFPH101A
Wireless pH and Temperature Transmitter

Part of the NOMAD® Family

⻬ Multiple Transmitter Configurations
⻬ Works with OMEGA® PHE-4200

Series of pH Probes

⻬ Real-Time Operation
⻬ Automatic Temperature

Compensation

Automatically Converts a

⻬ PC into a Strip Chart Recorder

The OM-CP-RFPH101A is a miniature,
wireless, battery-powered, standalone
pH and temperature transmitter. This
portable, easy-to-use device will read
and transmit pH and temperature
measurements. When enabled, the
wireless transmitter will transmit
readings back to the host computer,
where the data can be analyzed in real­time. These readings are also logged to
the device’s memory for added data
security. A convenient slide switch turns
the transmitter on or off.

The OM-CP-RFPH101A is a major leap
in both size and performance.
Numerous units can be used to transmit
data to the same receiving station. The
Windows software converts a PC into a
real-time strip chart recorder. Data can
be printed in graphical and tabular
format or exported to a text or Microsoft
Excel file.
