Product information

Digital pH meter with ISFET sensor

pH-metr

pH meter with ISFET sensor produced by ISFETCOM (Japan) enables pH measurements in small sample volumes (50 µl). Two-digit precision, temperature reading (Celsius degrees). One-point or two-point calibration. The sample is placed dropwise between ISFET sensor and reference electrode tip or the sensor part can be immersed into solution. Gel-filled reference electrode lifetime is typically 2–3 years, it may be regenerated or replaced.



To measure pH in even smaller sample volumes (2–5 µl) we developed our own version of the reference electrode. However, it is an experimental product, the guarantee of which is limited to 6 months due to its limited shelf-life.
