Waterproof pH, Redox, Conductivity, TDS and Salinity testers

Field/Laboratory/ Industrial

Instruments, Controllers & Sensors

Portable Waterproof pH, Redox (ORP), Conductivity, TDS and Salinity testers :

The very competitively priced R.M.S IP67 waterproof pocket-sized pH, Redox (ORP), Conductivity, TDS and Salinity testers are the WORLD'S FIRST testers to utilize user-replaceable electrodes to enhance the useful lifespan of the instruments. These feather-weight testers are most ideal for rugged outdoor use and wet applications. Newer version testers feature large screen display and simultaneous temperature readout, our new pH Spear tester (designed for use with food applications has a unique double junction electrode using special polymer gel electrolyte to provide reliable performance and quick stable results needed for difficult samples. We offer an extended 2 year warranty on our range of Pocket Testers.
