Description
PH850-SA portable pH meter is a compact handheld instrument for determining pH, ORP (electrode available separately, e.g. 301Pt-C) and temperature, optimised for precise measurements in strongly basic or alkaline solutions up to pH 14. The included LabSen® 843 combined pH/temperature electrode uses a specialised HA glass membrane that minimises alkali error at high pH values and can be used at temperatures up to 130 °C, making it suitable for high-temperature samples as well. A silicone sleeve gives a secure, impact-protected grip, while IP57 water- and dust-tight construction supports reliable field deployment in rough conditions. The meter from manufacturer APERA Instruments provides a fold-out stand for comfortable indoor operation, fast automatic 1- to 3-point calibration, self-diagnosis and a large backlit LCD that shows the measured value, temperature and calibration details at the same time. Measuring ranges cover 0,00 to 14,00 pH (resolution 0,1/0,01; accuracy ±0,01 ±1 digit), ±1000 mV and 0 to 100 °C with automatic or manual temperature compensation. Three AA batteries supply power. Instrument dimensions are 88 × 170 × 33 mm at 313 g (with case 360 × 270 × 76 mm / 1,3 kg). The set contains the PH850 meter, LabSen® 843 electrode, pH 4,00 / 7,00 / 10,01 calibration solutions (50 ml each), screwdriver, operating manual and carrying case.

Questions about PH850-SB Portable pH Meter for Strong Basic/Alkaline Solutions
What is this article?
PH850-SB Portable pH Meter for Strong Basic/Alkaline Solutions is the article on this page. Luminix Health distributes APERA Instruments for laboratory use. It sits in pH meters, inside pH & electrochemistry, in Lab instruments.
A pH meter reads the electrode and displays pH, after calibration with at least two buffers. A meter that cannot be calibrated is a voltmeter. Resolution to 0.001 is not the same as accuracy. Portable and benchtop meters differ in the electrodes they accept and in the data they store.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
