Description
The PH850-MS portable pH meter is a compact, user-friendly instrument for determining pH, ORP (electrode available separately, e.g. 301Pt-C) and temperature. It is designed especially for small sample volumes and narrow vessels such as test tubes. The included LabSen® 243-6 pH/temperature electrode has a slender construction that permits measurement of volumes down to 200 µl, and even to 60 µl with a suitable tube; it operates at temperatures up to 100 °C and incorporates a sensor for automatic temperature compensation (ATC). Protected by a silicone sleeve and rated IP57 water- and dust-tight, the meter from manufacturer APERA Instruments is well suited to field use in harsh environments. A fold-out stand supports comfortable indoor operation. Rapid 1- to 3-point automatic calibration, a large backlit LCD displaying pH and temperature plus calibration data, and self-diagnosis functions streamline routine work. Ranges cover pH 0,00–14,00 (resolution 0,1/0,01, accuracy ±0,01 ±1 digit), mV ±1000 and temperature 0–100 °C. Powered by three AA batteries, the unit measures 88×170×33 mm and weighs 313 g (with case 360×270×76 mm / 1,3 kg). Delivery includes the PH850 meter, LabSen® 243-6 electrode, calibration solutions pH 4,00/7,00/10,01 (50 ml each), screwdriver, manual and carrying case.

Questions about PH850-MS Portable pH Meter for Test Tubes and Small Sample Volumes
What is this article?
PH850-MS Portable pH Meter for Test Tubes and Small Sample Volumes 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.
