Beschrijving
PH700-SA tafelmodel pH-meter is ontworpen voor snelle, betrouwbare pH-metingen in het laboratorium met de LabSen 843 pH/temperatuurelektrode, geoptimaliseerd voor sterk alkalische oplossingen (pH > 12) en/of oplossingen met hoog zoutgehalte (> 0.5 % of 5000 ppm) en algemene waterige monsters. De Zwitserse LabSen 843-elektrode minimaliseert de alkalische meetfout onder deze veeleisende omstandigheden. De meter biedt automatische 1- tot 3-puntskalibratie met zelfdiagnose en weergave van de elektrodeconditie, Max/Min-afleesmodus voor snelle trendanalyse en opslag van 50 gegevenssets. Het pH-bereik is 0 tot 14 (resolutie 0.1/0.01; nauwkeurigheid ±0.01 ±1 cijfer) met BNC-elektrodeaansluiting en automatische of handmatige temperatuurcompensatie 0 tot 100 °C. Het mV-bereik is ±1999 mV; temperatuur 0 tot 100 °C. IP54 spat- en stofbeschermde behuizing. De elektrode heeft een loodvrije glazen schacht, HA-membraan, zilverionenvangreferentie, keramische junctie, 30 kΩ NTC-sensor en 3M KCl-elektrolyt; aanbevolen gebruik 0 tot 130 °C; afmetingen Ø12×120 mm met BNC/RCA-kabel. Compleet geleverd van fabrikant APERA Instruments met PH700-meter, LabSen 843-H-elektrode, elektrodehouder, kalibratieoplossingen pH 4 / 7 / 10.01 (50 ml elk) en DC 9 V-voeding. Meterafmetingen 24 × 23.5 × 10.3 cm; gewicht 1 kg (1.8 kg met koffer).
Dit artikel maakt deel uit van pH-meters, in pH & elektrochemie.

Questions about PH700 tafel-pH-meter incl. pH-elektrode
What is this article?
PH700 tafel-pH-meter incl. pH-elektrode is the article on this page. Luminix Health distributes APERA Instruments for laboratory use. It sits in pH-meters, inside pH & elektrochemie, in Instrumenten.
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.
