Portable pH Meter APERA PH850-PW for Deionized Water

The Apera Instruments PH850-PW portable pH meter provides professional pH measurement for drinking water, RO, distilled, and deionized water as well as other low-ion-concentration liquids. Equipped with the LabSen 803 3-in-1 glass pH/temperature electrode featuring a moving sleeve junction, long-lasting reference system, and patented dual-sensor pH/temperature design structure, it makes precise deionized water pH measurement easier than ever. Achieve stable readings in as little as 30 seconds. The unique LabSen blue cylindrical glass membrane offers faster response rate, better reproducibility, and extreme durability against impact—completely different from fragile traditional glass bulb membranes.

This PH850-PW portable pH meter features a measurement range of 0-14 pH with ±0.01 pH accuracy and temperature range of 0 to 80°C (32 to 176°F), with automatic calibration recognition for up to 12 different buffer solutions. It supports auto-temperature compensation and stable reading/auto-hold display mode. The meter's digital filter technology enhances response time and measurement accuracy.

Intelligent functions include self-diagnosis, out-of-range alerts, calibration error notifications, and electrode invalidation warnings. Additional features include automatic calibration, auto-lock, easy parameter adjustment, pH electrode slope display, and automatic shutdown. The rugged design includes a foldable stand for benchtop use, soft silicone protective case for secure grip, connector protection cap, IP57 dust and water resistance, and operation with 3 AA batteries. The device is RoHS and CE certified with a 2-year warranty.
