Product Description
The Hanna Instruments HI 981401N-01 is a water-resistant meter for continuous measurement of pH in agricultural and hydroponic applications with manual one- or two-point calibration, a single-line LCD screen, a plastic body pH electrode with waterproof sleeve, and a stainless steel grounding bar. A pH meter is commonly used to measure the pH of substances such as water, food, beer, or wine in lab, industrial and food applications.
The single line LCD screen of this meter shows the current measurement. Electrical circuitry is sealed inside the water-resistant housing. The meter has a flat back to prevent rolling when placed on a table and can be wall mounted using the molded eye. The meter is supplied with the HI 1286 double-junction, plastic-body, gel-filled combination pH electrode. The electrode resists clogs in fertilizer solutions with high concentrations of nutrient such as phosphate and nitrate. The connector is protected by a waterproof sleeve. The HI 1283 stainless steel probe prevents potential grounding problems and extends electrode life. The input impedance is 10 E 12 Ohm and the power supply is 115VAC. The meter also comes with buffer solution sachets, a calibration screwdriver, 12VDC adapter, and instructions

A pH meter, also called a sensor or tester, is a device used to measure the acidity or alkalinity of a substance. A pH meter has either a portable or a benchtop body. Many portable meters are handheld devices. Some testers have an internal sensor, and may have a tip and body that fit inside of a container for measurement. A meter is commonly used in many different environments from laboratories to field research and manufacturing facilities. Researchers, manufacturers, and hobbyists use a pH meter in aquaculture, agricultural, wine-making, and water-testing, and for scientific applications. Some pH meters may measure additional parameters such as dissolved oxygen (DO), conductivity (also called electro-conductivity or EC), temperature, total dissolved solids (TDS), salinity, resistivity, or oxygen reduction potential (ORP)/mV.
Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) standard 9001.
