{{EN_0} - 260 portable acidity meterDetailed product description：

The PHSB-260 portable acidity meter is a digital display meter with dual row digital display LCD, which can simultaneously display pH and temperature values. This instrument is suitable for testing the pH value and potential (mV) value of aqueous solutions in laboratories or fields of colleges, research institutes, environmental monitoring, industrial and mining enterprises, and other departments. It can also measure the ORP (oxidation-reduction potential) value of solutions when equipped with ORP electrodes. Paired with an ion selective electrode, the electrode potential value of the electrode can be measured.

PHSB-260 portable acidity meter features:
Four range, automatic switching, automatic carry display, simple operation, high measurement accuracy
Powered by four No. 5 dry batteries, it is easy to carry and can be used in the field
Adopting a 3-digit large LCD digital display, conductivity and temperature are displayed simultaneously, with a beautiful appearance and clear display
