Extech’s Rugged & Waterproof pH Meter Tackles Water Quality Testing

Tuesday, April 11, 2017


Makers of the best handheld test and measurement tools, recently announced the launch of the new PH90 Waterproof Digital pH Meter. The new stick-style meter is designed to ensure fast, easy spot testing for pH for a range of water quality testing jobs from commercial and industrial wastewater treatment, to aquafarming, to municipal drinking water authorities.

Technicians can ditch cumbersome litmus paper-based testing and consumables. The PH90 is always ready for field use by water quality managers at on-site wastewater treatment facilities, for example. Whether in an industrial plant or a large senior housing facility, it’s essential to ensure compliance with pH standards for effluent discharge so that ecosystems and public wastewater systems alike are not impacted adversely.  

The compact new meter measures and displays both pH and temperature simultaneously. Since temperature can have a direct effect on pH, the PH90’s Automatic Temperature Compensation (ATC) helps mitigates inaccurate readings as temperatures change. Unlike pH instruments with fragile glass-bulb electrodes, the durable flat-surface pH electrode is rugged for use every day, with measurements at multiple locations. Rated IP57, the meter can be dropped in liquids at a job site without worry—it’s waterproof and it floats for easy recovery.

Depending on testing needs, users can opt for 2 or 3 point calibration that automatically recognizes buffer solutions (available separately).  Useful data functions include Data Hold to freeze the display as well as Minimum and Maximum readings. To conserve battery life, the  PH90 automatically powers down after 10 minutes of inactivity. 

For added peace of mind, the PH90 is backed by a one year warranty. The meter comes complete with flat surface pH electrode, protective sensor cap, and two 3V CR-2032 button batteries. Replacement electrode modules and buffer calibration solutions are available separately from Extech.
