Apera PH850-SB Portable pH Meter for Strong Alkaline Solutions

The Apera PH850-SB is a specialized portable pH meter designed to measure strong alkaline solutions up to pH 14 and high-temperature samples up to 100°C. The Swiss LabSen 841 pH electrode features an H-type glass membrane that provides fast response time and high repeatability under these demanding conditions; the hemispherical glass structure is more impact-resistant compared to conventional bulb-type membranes.

The device measures across a 0-14 pH range with ±0.01 pH accuracy and features automatic calibration with automatic recognition of up to 12 buffer solutions. An intelligent self-diagnostic function alerts the user to out-of-range measurements, electrode failure, and incorrect calibration conditions. Digital filter technology enhances measurement accuracy and response time.

With IP57 waterproof rating and soft silicone protective case, the meter is suitable for field applications; it can also be used as a benchtop meter with the included foldable stand. The large backlit LCD display ensures readability even in low-light environments. An ideal practical solution for laboratories working with strong alkaline process waters, industrial cleaning solutions, and high-temperature samples.
