Transparent lid for easy maintenance and storage Ideal lid design for a stable stand Display colours & symbols for easy use New multi-parameter models for individual measurement requirements With its waterproof housing, the Pocket Tester is ideal for regular checks in industrial plants or swimming pools. Plus, the transparent lid not only provides a secure stand for the Pocket Tester in daily use, but also makes it easier to maintain the electrodes. A three-colour LED lighting system - blue, green and red - and new display icons make the tester easy to use and intuitive to operate. The use of energy saving LEDs and 4 x AAA batteries greatly extends the life of the new Pocket Tester range to up to 2000 hours. With the included lanyard, each SD Series tester can be worn comfortably around the neck or attached to a pocket, waistband or belt with the clip on the head of the tester, allowing it to be taken anywhere without tiring the hands.
