Beschrijving
Tafel-pH-meter METRIA model M21 is een ORP- en pH-laboratoriuminstrument met automatische of handmatige temperatuurcompensatie tussen 0 en 100 °C. Het dekt een pH-meetbereik van −1 tot 15 met resolutie 0.01 en nauwkeurigheid ±0.01, en een redoxbereik van ±1999 mV bij resolutie 1 mV. Een standaard BNC-connector accepteert pH- of redoxelektroden, terwijl een 3.5 mm telefoonstekker de CAT-temperatuursensor bedient. Automatische driepuntskalibratie volgt USA-buffers (pH 4.01, 7 en 10.01) of NIST-buffers (pH 4.01, 6.86 en 9.18). Een LCD met achtergrondverlichting en automatische holdfunctie vergrendelen het eindpunt voor duidelijke aflezing. Het pakket omvat bufferoplossingen (pH 4.01, 7 en 10.01), elektrodehouder, METRIA-elektrode PHEL-GB1-001 (maximale werktemperatuur 80 °C) en CAT-temperatuursensor PHMT-PT1-001. Werking is 220 V / 50 Hz; combinatie met magneetroerder STIS-000-001 wordt aanbevolen. Het nettogewicht is 1.8 kg voor één eenheid van fabrikant Labbox, met een garantie van twee jaar.

Questions about METRIA tafelmodel meter model M21, 1pcs, EU-stekker
What is this article?
METRIA tafelmodel meter model M21, 1pcs, EU-stekker is the article on this page. Luminix Health distributes Labbox 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.
