Isolated or Non-Isolated Output Models Available

4 to 20 mA Output

Manual or Automatic Temperature Compensation

The model PHTX-1 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(omega) Platinum RTD.

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, a convenient push-button switch is provided. The 4-20 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 OMEGE^®700 Series thermistor.
