Labtron pocket testers are small and compact in size, gives fast and accurate results. The Pocket testers consist of pH, ORP, TDS, dissolved oxygen, salinity and conductivity tester for various laboratory as well as outdoor applications. Measurements can be taken by inserting the probe in to the test solution and after gentle stirring, stable readings can be noted down.
