Portable digital pH meter 902/4

This pH meter laboratory, light, compact and easy to use, it is ideal for measurements of pH in situ.

Its size makes periodic checks of the pH level of laboratory, field and industry, as well as aquariums, swimming pools, wastewater, drinking water, rivers, springs, water culture, etc.

It has a liquid crystal display that can be easily read illuminated for easy reading in dimly lit places.

The membrane keyboard is resistant to moisture from the 4 keys that access to all functions of the instrument.

The equipment, supplied with a combination electrode with glass body, to measure the pH and electric potential of various kinds of solutions.

Supplied with a cell of 2 platinum electrodes (K = 1 cm-1) to measure the conductivity of solutions in a range of 0 to 1x105 µS/cm. In addition, the constant value can be modified to allow the use of other conductivity cell constant 10 cm-1, 1 cm-1 and 0.01 cm-1, and cover a wide variety of applications.

To adapt to the needs of each application, the equipment can be used with other types of electrodes provided that the BNC connector. The pH meter 902/4 also has a temperature compensation mechanism by introducing the temperature value via the keyboard.
