PH METER PHS-3C ACIDITY METER PHS-3C

PHS - 3C type
The pH meter is a digital display pH meter, which uses a blue backlight, double-row digital display liquid crystal, which can display pH value, temperature value or potential (mV) value at the same time. The instrument is suitable for laboratories in colleges, research institutes, environmental monitoring, industrial and mining enterprises and other departments to take samples to determine the pH value and potential (mV) value of aqueous solution. It can be equipped with ORP electrode to measure the ORP (oxidation-reduction potential) value of the solution. , coupled with an ion-selective electrode can measure the electrode potential value of the electrode.
DDS -11A Conductivity Meter
1. Performance characteristics:
DDS-11A conductivity meter is a laboratory conductivity measurement instrument, which is widely used in petrochemical, biomedicine, sewage treatment, environmental monitoring, mining and smelting industries, colleges and scientific research units. If it is equipped with a conductivity electrode with an appropriate constant, it can be used to measure the conductivity of pure water or ultrapure water in electronic semiconductors, nuclear energy industries and power plants.
