Updated and improved series of testers.
With the Pocket Tester, you can measure pH, ORP, conductivity, salt or TDS in the field in no time at all. With
its waterproof housing (IP67), the Pocket Tester is ideal for regular checks in swimming pools & spas.
A three-colour LED lighting system – blue (measurement), green (calibration) and red (errors) - and new
display icons make the tester easy to use and intuitive to operate.
A new multiparameter version is available. SD40 tests pH, conductivity, salt, TDS and temperature.
