อุปกรณ์วัด Control System (ORP Analog Controller with Self-Diagnostic Test)

HI 8720 ORP Analog Controller with Self-Diagnostic Test This instrument allows the selection of a set point for oxidizing or reducing dosage. When used in conjunction with the HI 8710 pH controller, the ODCD (ORP dosing consent device) function (featured by the HI 8710) will ensure that the ORP dosage will start only when the pH level is correct. These instruments have been designed for ... Read More »

อุปกรณ์วัด Control System (pH Analog Controller with Dual Output and Self-Diagnostic Test)

HI 8711 pH Analog Controller with Dual Output and Self-Diagnostic Test HI 8711 allows the selection of two set points with two independent outputs for acid and alkaline dosages. Each model accepts either a direct input from a pH or ORP electrode or from a transmitter through 4-20 mA input. The instrument also provides ±5V power output and input terminals for amplified electrodes. ... Read More »
