ATLAS ENV-30-PH

This pH probe is a consumer-grade single-junction silver/silver chloride probe for pH measurement. The measurement range is 2 - 13, resolution is +/- 0.1, accuracy is +/- 0.1, and 95% response time is 4 seconds. The temperature range is 1 - 60°C, maximum pressure is 50 PSI, and maximum depth is 35 meters (114 feet). The connector is a male SMA/male BNC (optional), cable length is 1 meter, with no internal temperature sensor, time before recalibration is approximately 3 months, and expected lifespan is approximately 12 - 18 months. The pH probe measures hydrogen ion activity in liquids through a glass membrane; the minute current generated by differences in hydrogen ion concentration is proportional to the hydrogen ion concentration in the measured liquid. Acidic solutions have pH < 7, neutral solutions have pH = 7, and alkaline solutions have pH > 7. The probe is constructed from polycarbonate (shatter-resistant), Ag/AgCl electrodes, KCl reference solution, junction, rubber seal, silver wire, and glass membrane. This probe is NSF/ANSI 51 certified and food-contact safe; the materials used — including PVC, ABS, glass, nitrile rubber, polyethylene, polycarbonate, and titanium nitride — all comply with the NSF-51 standard.
