The pHTestr® 20 is an accurate hand held tester which accurately measures pH up to ±0.01 pH accuracy at 0.01 pH resolution. The addition of Automatic Temperature Compensation (ATC) ensures accurate readings in varying conditions. The pHTestr® 20 is user-friendly and has a large cutsom dual display which provides all the necessary information the user requires.
Sensors are easy to replace as they screw off the end of the device. The pHTestr® 20 has the benefit of a double-junction sensor with chemical resistant kynar® porous junction which minimizes clogging and contamination and longer electrode lifespan with increased polymer gel volume.
