Description
Benchtop pH meters SevenDirect™ SD20 Pure H2O kit combine a laboratory pH meter with the InLab® Pure Pro-ISM® electrode and a full buffer set for aqueous low-ionic-strength work. Included buffer solutions cover pH 4.01, 7.00, 9.21 and 10.00, each provided as 2 × 20 ml, supporting multi-point calibration across common reference points. An electrode holder and protective cover are part of the kit so the instrument can be arranged as a stable benchtop measuring station. Offered as 1 pc(s) from manufacturer Mettler-Toledo, the SevenDirect™ SD20 Pure H2O kit pairs the meter with a sensor intended for pure-water type samples and ISM® intelligent sensor management. Pharmaceutical, environmental and research laboratories can deploy the package for controlled pH readings where conventional electrodes are less suitable for low-conductivity media. Having matched buffers in the box simplifies start-up and routine recalibration. The stated unit weight is 0,850 kg. This configuration supports everyday and regulated pH determination on the SevenDirect™ SD20 platform whenever pure aqueous samples are the primary matrix.
This article is part of pH meters, in pH & electrochemistry.

Questions about Benchtop pH meters, SevenDirect(TM) SD20 Pure H2O kit, 1 unit(s)
What is this article?
Benchtop pH meters, SevenDirect(TM) SD20 Pure H2O kit, 1 unit(s) is the article on this page. Luminix Health distributes Mettler-Toledo 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.
