Automatically Converts Your PC into a Strip Chart Recorder
Description
The OM-CP-RFPH101A Series has been discontinued. Please see the UWPH-2A-NEMA-M12 as
a possible alternative or contact our Data Acquisition Engineering department.
The OM-CP-RFPH101A is a miniature,
wireless, battery powered, stand-alone,
pH and temperature transmitter. This
all-in-one compact, portable, easy to use
device will measure 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 real time. These readings are also
logged to the device’s memory for added
data security. The convenient slide switch
allows the transmitter to be turned On or
Off without affecting the operation of the
device. The OM-CP-RFPH101A is a major
leap forward in both size and performance.
Numerous devices may transmit data to the
same receiving station. The Windows
software converts your PC into a real time
strip chart recorder. Data can be printed in
graphical or tabular format and can also be
exported to a text or Microsoft Excel file.
