This is the Accurate pH 3. This waterproof meter is a step up from Control Wizard Products' Accurate pH 2 meter. It's readings are shown in whole, tenths and hundredths of a pH point.
It has a one-point calibration process for fast and accurate tests. This process requires the pH 7.0 calibration solution (sold separately).
The electrode (CW504) is easily replaceable by the consumer and is relatively inexpensive.
The Accurate pH 3 comes complete in a simulated leather storage pouch with lanyard, a screwdriver, batteries, a complete instruction manual and a one-year warranty with receipt. Waterproof to one meter.
