The Oakton 35425-10 Oakton Multiparameter 35-Series PTTestr 35 is a handheld, waterproof, and dustproof pocket meter that measures pH, conductivity, and temperature and floats, if dropped in liquids. A portable pocket meter is commonly used to measure the pH of substance in hydroponics, agriculture, industrial process checks, water , and swimming pools. This meter features ATC for accurate readings in fluctuating temperatures, and push-button calibration capabilities for a wide range of results. It has stainless steel, pin-type conductivity sensors for durability and compatibility with a wide variety of samples. 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)-protected reference junction with polymer gel for longer lifespan. The meter has a large, upright, dual-line LCD screen for ease of viewing, a hold function which freezes readings for , 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 35425-10 pocket meter has ATC from 0 to 50 degrees C (32 to 122 degrees F), or manual ability, and an operating temperature range of 0 to 50 degrees C (32 to 122 degrees F), resolution 0.1 degree, + or - 0.5 degrees C (+ or - 0.9 degrees F). It has 1-point temperature, 1-point salinity, 3-point TDS, 3-point conductivity, and 5-point pH calibration capability range. pH range is 0.0 to 14.0, resolution 0.1, accuracy + or - 0.1. TDS range 0 to 99.0 ppm; 100 to 999 ppm, 1.00 to 10.00 ppt, resolution 0.1 ppm, 1 ppm, 0.01 ppt, accuracy + or - 1% full-scale. Conductivity range 0 to 200 μS; 201 to 2000 μS, 2.01 to 20.00 mS, resolution 0.1 μS, 1.0 μS, 0.01 mS, accuracy + or - 1% full-scale. Salinity range 0 to 10.00 ppt, 0.1 ppm, 1 ppm, resolution 0.01 ppt, 0.01%, accuracy 1% full-scale. Its dimensions are 1.25 (w) x 6.5 (h) inches (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 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. Conductivity meters measure the ability of a material or solution to conduct an electrical current. TDS such as salts and minerals contribute to the conductivity of a solution. A TDS meter measures the conductivity and converts it to a TDS reading. Oakton Instruments manufactures an array of scientific instruments for research, industrial, and educational uses.
