AZ Waterproof EC & TDS meter Pen (8362)

AZ Waterproof EC pens raise the bar in ease of use, reliability, function and price point. AZ meters provide a big IP65 LCD screen with dual EC and temperature display. Wide measuring range from 0-9999ppm and a temperature range of -5°C to +60°C. Waterproof IP65 keypad with simple calibration. Also includes a hold button to freeze current readings in low visibility. ATC (auto temperature compensation) ensures accurate readings in all climates. Auto off function maximizes battery life. Wide measuring range up to 160mS Dual display Temp. & Conductivity or TDS with ATC Water proof IP65 membrane keypad Low cost design with high accuracy Quick response and easy to calibrate Adjustable TDS factor from 0.3 to 1.0 Auto power off Hold function to freeze current measurement. AZ EC Pen Model No. 8362 range explained: For accuracy at very low EC (0 - 1.99 mS) the AZ EC pen measures in µS (microsiemens) , then (above 1.99 EC) measures in mS (millisiemens): 0 - 1999 µS (microsiemens) = 0 - 1.999 mS (millisiemens) or as we refer to in hydro 0 - 1.99 EC. This range is for low-conductivity solutions, like pure or lightly salted water (e.g., drinking or tap water or hydroponics with very low nutrient levels). 2.00 - 19.99 mS (millisiemens) or 2 - 19.99 EC: This range is for medium-conductivity solutions, such as irrigation water or nutrient solutions in hydroponics. 20.0 - 160.0 mS or 20 - 160 EC: This range is for high-conductivity solutions, like seawater or heavily fertilised solutions.
