Desktop pH / ec meter voor laboratorium gebruik.
Meet pH, redox potential (ORP), geleidbaarheid, zoutgehalte, weerstand, TDS en temperatuur.
Simultaan weergave van de meetresultaten van de gekozen functies op het kleuren grafisch touchscreen.
Groot meetbereik maakt het mogelijk om allerlei typen vloeistoffen te meten zowel ultra puur als zware zoutoplossingen.
Kalibratie in 1 tot 3 waarden, aanpasbaar.
Automatische correctie van de pH standaard oplossing waarde afwijkingen, afhankelijk van de temperatuur voor de NIST standaard.
Automatische aanpassing van de temperatuurcoefficient voor natuurlijk en ultra puur water in de EC-mode.
Geheugen voor 500 meetsets, volgens GLP, USB output, software inbegrepen.
The standard set includes:
ECF-1 conductivity sensor,
CT2S-121 temperature sensor with
Pt-1000S resistor,
EPS-1 pH electrode for measurements in clean water. It should not be used in other types of liquid. Measurements in liquids with sediments should be made with use of
IJ-44A pH electrode, which enables measurements in various samples of both pure and contaminated liquids and semi-solids. Its unusual construction (”intermediate junction”) protects the real junction (diaphragma) of the electrode against clogging, ensures stable measurements in these types of liquids or semi-liquid masses, in which other electrodes stop working quickly. When properly handled and maintained the electrode's lifetime is longer than the standard electrodes.
