Conductivity Digital Panel Meters - accurate & easy to use, 3 year warranty.

INT4-B Conductivity digital panel meter - easy to use!

INT4-B digital panel meter for conductivity


The INT4-B is part of our most popular 1/8 DIN panel meter series. It measures DC surface conductivity. It is not intended for TDS applications.

We design, manufacture and supply to all parts of the world. Prices for all our products are on the price list page in the manuals and forms section.

Technical operating manuals for digital panel meters available with instant access

Precise ...
This digital panel meter is easy to use and has high precision and stability. You can set the display to have 2, 3, 4, 5 or 6 digits, depending on the type of measurement you want to make. You can also set the decimal point position.

Flexible ...
This panel meter can be fitted with isolated output signal modules to add control and data sharing functions.

Tamper Proof ...
This digital panel meter is also available with a plain front panel. All settings can be locked to prevent changes after commissioning.

The small window in the bottom right can have text such as S, mS, uS, nS etc.
The display colour is available in red or green.



They are British made and designed to be easy to use, reliable and precise.

They are flexible also, thanks to the wide range of plug-in options you can add, to provide control and data functions.
