Waterproof pH Meter GMH 5530 / GMH 5550
Waterproof pH Meter with Datalogger / Serial interface / Analog output / Large Dual Display / Calibration function / Robust Silicone-Case / IP 67 Protection

Due to a waterproof construction, the GMH 5530 / GMH 5550 is qualified for use under wet conditions. It can even be used under extreme conditions due to a robust ABS enclosure. The measuring data is shown directly on an extra-large display, depending on the connected sensor. The 1-, 2- or 3-pin calibration as well as an automatic temperature-compensation guarantee high precision, even when the measuring temperature oscillates. These features allow a quick and reliable measurement. Furthermore, pH- data, temperature and REDOX-potential (ORP) can be detected.
