Description
PH700-MS benchtop pH meter is designed for rapid, accurate laboratory pH measurement of micro-volumes down to 15 microlitres of aqueous solutions, biological samples and protein-containing media. It is equipped with the Swiss LabSen 241-3SP pH/temperature electrode featuring a long-life reference system, ceramic junction and fine measuring tip (Ø3 × 16 / Ø4 × 54 mm) ideal for smallest sample volumes. The meter from manufacturer APERA Instruments offers automatic 1- to 3-point calibration with self-diagnosis and electrode-status indication, Max/Min mode for quick evaluation over time, and capacity for 50 stored data sets. pH range covers 0,00–14,00 at resolution 0,1/0,01 and accuracy ±0,01 ±1 digit; mV range ±1999 mV; temperature 0–100 °C with automatic or manual compensation. The IP54-rated housing measures 24 × 23,5 × 10,3 cm and weighs 1 kg (1,8 kg with case). Delivery includes the PH700 meter, LabSen 241-3SP electrode, electrode holder, 50 ml buffers pH 4,00 / 7,00 / 10,01 and DC 9 V power adapter. Manufacturer warranty is 2 years on the instrument 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.
