Apera PH850-PW Portable Pure Water pH Meter with LabSen 803 Electrode

Portable pH Testing for Pure and Low-Ion Water The Apera Instruments PH850-PW portable pH meter pairs with the LabSen 803 glass 3-in-1 pH/temperature electrode for testing reverse osmosis (RO), distilled, deionized and drinking water, as well as other low-ion-concentration solutions. Take measurements on the move, or use the foldable stand to position the meter on a workbench. Key Features Pure-water electrode: LabSen 803 with an integrated temperature sensor, movable sleeve junction and silver ion trap reference. Temperature compensation: Automatic or manual compensation to support pH measurement. Calibration and diagnostics: Automatic calibration, electrode slope display, out-of-range diagnostics and electrode invalidation alerts. Portable design: IP57-rated meter with a soft silicone case, foldable stand and automatic power-off. Power options: Three AA batteries or DC 5V through the USB port.

When using the included LabSen 803, stay within its specified 1–11 pH and 0–80°C operating ranges. Applications Use the PH850-PW for pH checks in RO water systems, distilled or deionized water workflows, drinking water testing and other low-ion water applications. This instrument measures pH and temperature; a pH reading alone does not establish drinking-water safety.
