DPH-4 Dual pH & ORP Controller Manual

The DPH-4 instrument was built with flexibility in mind. It can be set up as Commercial pool controller measuring PH/ORP, or it can be used as a process controller measuring PH/ORP, PH/PH or ORP/ORP.

Setup and calibrations are entered with easy to use encoders. Programmed parameters are not lost even if power is switched off for extended periods.

Precision 4-20mA output with complete isolation between each unit enables the connection to a central monitor or data

logging system. mA calibration and signal range are performed through software and kept in non-volatile memory.

Various timing modes and dosing relay lock-out times protect the installation from excess dosing.
