Description

PHT20 is a reliable pH/ORP transmitter, enclosed in a small housing for DIN- rail mounting or in box mounting. PHT20 converts the high impedance voltage output of pH or REDOX (ORP) probes into standard current or voltage signal that can be safely sent over longer distances. The transmitter provides the necessary for the normal pH/ORP probe’s operation and has an additional Pt100, Pt1000 or NTC 1k input for automatic temperature compensation. The transmitter provides linear current or voltage output and can also be equipped with a relay alarm/control output. All device parameters (preset conductance ranges, analog output range and direction, relay set point, hysteresis, and direction, temperature compensation parameters, etc.) are user-programmable via the RS232 interface.. Thanks to its wide measurement range, flexibility, programmability, and reliability, the PHT20 transmitter is very suitable for water treatment and processing applications in the food, pharmaceutical, and many other industries.
