## Description

AZ-8685 pH pen is a handheld, waterproof, and dustproof pocket meter that measures pH and floats, if dropped in liquid.  A portable pocket meter is commonly used to measure the pH of substance in hydroponics, education, water treatment, and swimming pools. This meter has ATC for accurate readings in fluctuating temperatures, and push-button calibration capabilities up to three points for a wide range of results. It features a transparent, protective cap to reduce contamination and protect the sensor. The cap keeps the sensor moist when stored upright, and can be used as a container for sensor-conditioning, or on-site calibration. The meter's waterproof and dustproof housing has IP67-rating for protection against solid objects or liquids. The tester has a long-lasting sensor with Polyvinylidene Fluoride (PVDF) reference junction with polymer gel for long lifespan. The meter has a large, upright, single-line LCD screen for ease of viewing, a hold function which freezes readings for recording, and an auto shut-off to extend the life of the batteries.
