Description
PH700-BC benchtop pH meter delivers precise laboratory pH measurement of biotechnology and pharmaceutical samples, including biological fluids, enzyme solutions, protein-containing media, TRIS buffers, liquid foods (milk, yoghurt, sauces), beverages and general aqueous solutions. It is paired with the Swiss LabSen 823 pH/temperature electrode that uses Protelyte electrolyte and three ceramic junctions for stable readings in protein-rich matrices. The instrument from manufacturer APERA Instruments features automatic 1- to 3-point calibration with self-diagnosis and electrode-condition display, Max/Min reading mode, and storage of 50 data sets. pH measuring range is 0,00–14,00 (electrode 1–14) with resolution 0,1/0,01 and accuracy ±0,01 ±1 digit; mV range ±1999 mV; temperature 0–100 °C with automatic or manual compensation. IP54 splash- and dust-protected housing measures 24 × 23,5 × 10,3 cm and weighs 1 kg (1,8 kg with case). Scope of supply comprises the PH700 meter, LabSen 823 electrode, electrode holder, 50 ml calibration solutions pH 4,00 / 7,00 / 10,01 and DC 9 V power supply. Manufacturer warranty is 2 years on the meter and 6 months on the electrode.

Questions about PH700 Benchtop pH Meter incl. pH electrode
What is this article?
PH700 Benchtop pH Meter incl. pH electrode 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.
