HI 8710 pH regulator
direct connection to pH electrodes / fixed or automatic temperature compensation / 4-20 mA analog output / IP44 (Front) / 1 x alarm relay and 1 x control relay

The HI 8710 pH regulator is a two point discontinuous regulator designed to be installed in a control cabinet. The HI 8710 pH regulator can be used in many industrial sectors. The pH value regulation is made through a relay which can be connected to a metering pump. The front of the HI 8710 pH regulator is offers a polystyrene cover (IP44) to be used in the industrial sector. The HI 8710 pH regulator is handled by means of keys at the front panel where the display is also located. Front LEDs indicate the user the mode in which the HI 8710 pH regulator is operating. Three modes can be selected through a switch: On, Off and auto modes. Additionally, built-in test functions allow the user to get fast checking of both the sensor and the internal electronics. The pH electrode can be directly connected to the pH regulator. Maximum cable length: 10 m. For longer distances, an analog input can be used (4-20 mA). In this case, it is necessary to install a transducer in the measurement place. This transducer will convert the pH value into a 4-20 mA signal. The HI 8710 pH regulator has an analog output (0/4-20 mA) to send the average pH value to other devices. At the following link you will find all the pH regulators available at PCE-Instruments.
