Sensorex’s S465 series probes offer an alternative to Acu-Trol® pH and ORP probes used in industrial, municipal and potable water applications. The S465 series was designed expressly as a direct fit replacement for existing Acu-Trol pH and ORP probes. Constructed of durable PPS, S465 probes offer improved chemical resistance. Additionally, Sensorex uses a higher volume of its proprietary polymer sensor reference gel for longer service life. Sensorex’s advanced sensor technology delivers accurate measurement over a range of 0-14 pH or -1000–1000mV for ORP. The probes are suited to a variety of applications with a temperature range of 0-80 degrees C and a pressure maximum of 100psig (standard de-rating applies).
