Product Description
The Hanna Instruments HI 981404N-02 is a continuous measurement meter of pH and total dissolved solids (TDS) with manual calibration, two LCD screens, an interchangeable gel-filled pH electrode with Bayonet Neill-Concelman (BNC) connector and waterproof sleeve, a fixed TDS probe, a grounding bar, and a housing for wall mounting. A pH meter is commonly used to measure the pH of a substance. A TDS meter measures substance conductivity through presence of dissolved solids such as salts and minerals. pH and TDS meters are commonly used by researchers, manufacturers, and hobbyists in aquaculture, agriculture, hydroponics, and water-testing, and for scientific applications.
The two single-line LCD screens of this meter continually show the pH and TDS values. Front trimmers allow manual pH calibration at one or two points and TDS 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. TDS measurements are performed using the 4-4-2 conversion factor of 0.7. A grounding bar with a 2m (6.6') cable ensures accurate pH readings and prolongs electrode life. The power supply is 230VAC. The meter also comes with calibration solutions, 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.
