Sensorex S150C, S151C-ORP Sensorex’s S150C and S151C-ORP Polycarbonate Body 12mm pH/ORP Electrodes can be used with any pH or ORP meter and feature durable polycarbonate body construction. The electrodes feature Sensorex’s newly designed tip, which offers pH bulb and ORP platinum protection while maintaining optimum flow through the slots in the body. The S150C has a measurement range of 0-14 pH (0-12.3 pH without Na+ error), and the S151C-ORP has a measurement range +/-1999mV for ORP. It has a pH response speed of >90 percent in 1 second. The electrode operates up to a maximum temperature of 140 F (60 C) and up to a maximum pressure of 50 PSIG. The S150C and S151C-ORP offer wetted materials constructed from polycarbonate, silicone, pH glass or platinum. The sensors come with a standard 30-inch cable and BNC connector (US Std. and DIN available at additional cost). Both electrode models are RoHS-compliant. –
