Product Description

The Oakton 35423-10 EcoTestr pH 2 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 testr 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. It has a click-lock battery cover for battery access to replace batteries without tools.

The 35423-10 pocket meter comes with an integral sensor, has ATC from 0 to 50 degrees C (32 to 122 degrees F), and works in an operating temperature of 0 to 50 degrees C (32 to 122 degrees F). It has three-point automatic calibration at three US buffer values of US 4.0, 7.0 or 10.0. pH range is 0.0 to 14.0, resolution 0.1, accuracy + or - 0.1. Its dimensions are 1.25 (l) x 1.5 (w) x 6.5 (h) inches (3.2 x 3.8 x 16.8 cm) and it weighs 3.25 ounces. The testr works with four 1.5-V alkaline batteries (not included) for up to 250 hours of continuous use (Eveready A76 or LR44 replacements).

pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics, wine-making, and water-testing, and for scientific applications.
