The Extech PH90 Waterproof pH and Temperature Meter is a compact field instrument with a rugged flat-surface electrode for testing liquids, semi-solids and solid materials. Unlike a conventional glass-bulb electrode, the flat sensor is less prone to breakage or blocked junctions.

The IP57-rated housing, automatic temperature measurement and replaceable sensor make the PH90 suitable for regular field or laboratory use where fast pH checks are required.
