This pocket tester is fitted with a conductivity probe on a 1m long cable and has a measurement range of 0.00 to 10.00mS with 0.01mS/cm resolution.

Primo 4 is a rugged and reliable tester for quick and accurate conductivity testing. Perfect for use in hydroponics, drinking water and aquariums.

The PRIMO4 is ideally suited to the rigorous demands of water quality professionals who will appreciate the practicality of the clear, easy to read LCD for demonstrating the before and after results of conditioning and filtration systems.

Temperature is compensated automatically to ensure the readings are consistent to the standard or reference temperature.
