HM Digital Meters PH-80 pH/Temperature Meter

Reliable and affordable pH meter, ideal for measurement applications such as hydroponics and gardening, pools and spas, aquariums and reef tanks, water ionizers, drinking water, and more.
Resolution: pH 0.1 pH, 0.00–14.0 pH. Accuracy of +/-0.1 pH. Hold button and automatic shutdown. Automatic calibration: automatic adjustment to 4, 7, or 10 pH. Very reliable and long-lasting. Low battery indicator. Transparent cap to note the humidity (or its absence) on the probe. Glass-encapsulated reference electrode that helps retain moisture. Batteries included.

Technical specifications

How to use

• Calibrate with pH 4.0 and 7.0 buffer solutions before first use and once a week thereafter
• Rinse the electrode with distilled water before and after each measurement
• Store the probe cap with storage solution or pH 7.0 buffer
• Never let the electrode dry out — this permanently damages the glass membrane
• Replace the electrode when it cannot be calibrated within the normal range
