PH-099, designed for simultaneous pH and ORP measurements.
It also reads temperature, which is continuously displayed on the dual level LCD.
It is a waterproof pH, ORP and temperature meter.
All pH readings are automatically temperature compensated(ATC).
Measurements are highly accurate with a unique stability indicator right on the LCD.

The pH electrode, supplied with the meter, is interchangeable and can be easily replaced by the user.
