  The compact PHTX-8710 is a microprocessor based compact 4 to 20 mA current loop transmitter designed to meet your industrial fluid monitoring and control challenges. The front panel of the PHTX-8710 is rated to NEMA-4X/IP65, standard and the captive silicone gasket ensures watertight integrity in all mounting configurations. The unit is designed for panel mounting, with captive screws to simplify installation. Optional hardware kits accommodate pipe, surface and tank lid installations. Three push-button keys control all setup and system calibration functions. The 8- digit alphanumeric LCD shows every step in clear language. Calibration is literally a 1-2-3 operation.

  The PHTX-8710 pH/ORP transmitter is priced at $438.
