Water analysers

Combining three testers into one, the Testr 11 waterproof pocket testers are used for conductivity, total dissolved solids (TDS) and salinity measurements. In addition to original features, the series measures a wider range of media.

The preceding series, Testr 10, included high, low and pure models, which measure solutions with high conductivity, natural water and pure water respectively. The new series can now take readings from pure water to wastewater with one tester. The testers also come with multipoint calibrations for more accurate readings.

At ±1% full scale accuracy, the series offers good accuracies in a pocket-sized tester. Features include simultaneous temperature readouts, adjustable TDS factor, automatic temperature compensation (ATC), manual calibration, user-replaceable sensors, large LCD, ribbed body and waterproof to IP67 standards.
