The model PHTX-014 pH two wire transmitter is designed
to provide a standard 4 to 20 mA current output which is
proportional to the pH being measured. Its small size and
encapsulated construction allow for easy installation and
will accommodate any pH electrode with a BNC connector.
Temperature compensation is either manual or automatic
with use of any 1000 Ohm Platinum RTD.
The PHTX-212 is
the same as the PHTX-014 but with a range of 2 to 12 pH. This is a popular choice
for use with recorders or any application where it is convenient to divide the output
into ten division.
The PHTM-ORP is for an ORP electrode input with a range of 0 to 2000mV.
The PHTX-11 features include a NEMA-4X housing,
an integral LCD display for continuous pH reading or for
a direct corresponding readout in milliamps, using a convenient
push-button switch. The 4 to 20 mA output signal may be
scaled in the field to meet specific pH ranges in any 1 to 14 pH
unit increment. Temperature compensation is manual using a
fixed resistor or automatic using any of OMEGA’s
OL-700 Series thermistors probes.
