PHTX
|
The
PHTX series Preamps are unity gain preamplifiers which convert
the high impedence mV signal of a pH or ORP electrode to
a low impedence signal which can travel 1,000 feet over
ordinary wire and connectors. They may be used with pH meters
and controllers (such as the INPCpH) which include high
impedence input circuitry and also with Process Meters and
and Controllers such as the INFCP and INFP. In many applications
the PHTX-20 series Preamps will also extend the useful life
of expensive pH electrodes, lowering the output impedence
of an aging electrode allowing it to continue providing
a measurable signal. |
