Water resistant, accurate and portable, this handy little pocket meter is a 'go anywhere' pH tester, with a replaceable electrode. Also designed to float if accidentally dropped into water. Dual LCD showing pH and temperature readings simultaneously. The exposed temperature sensor provides fast response time. For convenience the pH readings can be held on the LCD using the HOLD button and the meter will automatically switch itself off to preserve battery life. Calibration is automatic (1 or 2 points) using push buttons with a choice of five buffer values. The pH electrode has a protective cap and a non-clogging fibre reference junction for long life. It can be easily replaced by the user by simply plugging in a new one.

• Supplied complete with electrode, electrode removal tool, batteries and instructions.
