Probes, pH & ORP

Halma India offers Sensorex’s S465 series Probes, an alternative to Acu-Trol® pH and ORP probes used in swimming pool control, 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°C and a pressure maximum of 100 psig (standard de-rating applies). The threaded ½” NPT connection enables easy in line installation or use with existing Acu-Trol flow cells without modification. Advanced signal shielding reduces noise for more accurate communication with process control systems. Both the pH and ORP probes are available with a BNR connector for quick integration into existing systems.

Sensorex is a global leader in design and manufacture of quality sensors for water applications. The company offers more than 2000 sensor packages for pH, ORP, conductivity, dissolved oxygen, free chlorine, chlorine dioxide and other specialty measurements, as well as a full line of sensor accessories.
