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.
