Extech PH90 Waterproof pH and Temperature Meter

Looking for a better solution than traditional pH meters which use traditional glass bulb electrodes that can easily break or get clogged when in use? Extech's PH90 is the meter you've been looking for.

Equipped with a rugged, replaceable flat surface pH electrodes, the Extech PH90 can be used to test the pH levels and temperature or liquids, semi-solids and solid materials. It's suited for use in many different applications, including agriculatural areas, anti-freeze recycling, aquariums, boilers, chemical analysis, cooling towers, drinking water, fish farming, the food industry, gardens, hydroponics, laboratories, plating industires, swimming pools/spas and for water treatment.

When testing, the Extech PH90 will simultaneously calculate and display both pH and temperature. Built-in automatic temperature compensation ensures that your readings are as accurate as possible and not affected by temperature levels.

This pH meter comes with a number of additional features including a data hold function which temporarily freezes current values shown on the screen, a MIN/MAX mode which calculates maximum/minimum values over a period of time and automatic power off and low battery indicators.

If you're using the Extech PH90 in a wet environment there's no need to worry - the meter is rated to IP57 and floats in water.
