The Oakton 35423-10 EcoTestr pH 2 is a handheld, waterproof, and dustproofpocket meter that measures pH and floats, if dropped in liquid. A portablepocket meter is commonly used to measure the pH of substance in hydroponics,education, water treatment, and swimming pools. This meter has ATC foraccurate readings in fluctuating temperatures, and push-button calibrationcapabilities up to three points for a wide range of results. It features atransparent, protective cap to reduce contamination and protect the sensor.The cap keeps the sensor moist when stored upright, and can be used as acontainer for sensor-conditioning, or on-site calibration. The meter’swaterproof and dustproof housing has IP67-rating for protection against solidobjects or liquids. The testr has a long-lasting sensor with PolyvinylideneFluoride (PVDF) reference junction with polymer gel for long lifespan. Themeter has a large, upright, single-line LCD screen for ease of viewing, a holdfunction which freezes readings for recording, and an auto shut-off to extendthe life of the batteries. It has a click-lock battery cover for batteryaccess to replace batteries without tools. The 35423-10 pocket meter comes with an integral sensor, has ATC from 0 to 50degrees C (32 to 122 degrees F), and works in an operating temperature of 0 to50 degrees C (32 to 122 degrees F). It has three-point automatic calibrationat 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) x6.5 (h) inches (3.2 x 3.8 x 16.8 cm) and it weighs 3.25 ounces. The testrworks with four 1.5-V alkaline batteries (not included) for up to 250 hours ofcontinuous use (Eveready A76 or LR44 replacements). pH testers measure the acidity or alkalinity of a substance and are commonlyused by researchers, manufacturers, and hobbyists in aquaculture, agriculture,hydroponics, wine-making, and water-testing, and for scientific applications. Oakton Instruments manufactures an array of scientific instruments forresearch, industrial, and educational uses. Since 1991, Oakton has distributeda wide variety of instruments such as meters, electrodes, and transmitters.Oakton is based in Vernon Hills, IL, and has facilities in Europe, Asia, andChina. What’s in the Box? Meter 35423-10 Integral sensor Age of the solutions, storing of the solutions, contamination of the solutions can all affect readings. Accuracy depends on caliberation standards, type of water or how the meter is stored. Are you testing RO water, distilled water, de-ionized water? Over time these liquids will drain the electrode of IONS and render the meter useless. Water of this type has no IONS so the salt solution within the probe will migrate out of the pH probe into the water. Naturally IONS move from high concentration to low concentration to create equilibrium. You can always use a TDS meter to test the water, you should get a reading around 0.00ppm. How should the Testrs being stored? In OAKTON storage solution. The storage solution contains the same liquid that is inside of the electrode which helps replenish and create longer life. Electrodes take on the characteristics of the liquids they are measuring over time, that’s why a lot of complaints about meter is stuck on one reading.
