This advanced pH, ORP and Temperature meter specifically designed to provide precise measurements even under harsh conditions. Equipped with ATC, automatically adjust itself to correct temperature discrepancies during use.

Use to measure the redox potential of your aquarium, pond, spa or pools and soil. Use it sea water aquarium for controlling of an ozone addition as well as in sea and freshwater basins. Ideally also to the indirect chlorine measurement in the swimming pool and other various industrial application.

Features:

1. Uses replaceable pH electrode & ORP electrode
2. With ATC
3. With BNC connections for use with a replaceable electrode
4. Clear readings even in the darkest of environments
5. Easy to use interface and monitors data continuously
