The Hanna Instruments HI 981405N-01 is a continuous measurement meter of pH and electro-conductivity (EC) for agricultural, horticultural, and hydroponics applications with manual calibration, two LCD screens, an interchangeable gel-filled pH electrode with Bayonet Neill-Concelman (BNC) connector and waterproof sleeve, a fixed EC probe, a grounding bar, and a housing for wall mounting. A pH meter is commonly used to measure the pH of a substance such as water, food, beer, or wine in laboratory, industrial, and food applications. The two single-line LCD screens continually show the pH and EC values. Front trimmers allow manual pH calibration at one or two points and EC calibration at one point. The meter has a flat back for wall mounting. The gel-filled pH electrode is replaceable and the BNC connector is protected with a waterproof sleeve. The electrode resists clogging in fertilizer solutions with high concentrations of nutrient, such as phosphate and nitrate. The meter has a fixed EC probe. A grounding bar ...
