Product Description

The Hanna Instruments HI 991401-01 waterproof pH and temperature meter with large LCD provides continuous monitoring of pH and temperature in agricultural and hydroponics applications. Designed specifically to meet growers' needs, the instrument is wall-mounted and the backlit LCD screen is easy to read, even in dim light. The instrument has a stability indicator and a Hold feature that freezes the display for manual recording. It provides automatic calibration, buffer selection, and temperature compensation. Calibration can be verified with one or two point calibrations. The 12VDC power supply included with the meter eliminates battery failure issues.

The pH electrode provides high resistance to clogging in fertilizer with high concentrations of phosphate, nitrate, and other solutions to extend electrode life. The monitor comes with an HI 1293D pH electrode, HI 1294 temperature probe (fixed), pH buffer solution sachets, and a 12VDC adapter.

A multiparameter meter is a benchtop or handheld device that can take multiple readings on a single sample. It measures parameters such as the pH level (acidity or alkalinity of a substance), conductivity (the amount of salts or other compounds present in water), dissolved oxygen (DO, the amount of oxygen in a liquid), temperature, total dissolved solids (TDS, anything present in water other than the pure water molecule and suspended solids), salinity, resistivity, and oxidation reduction potential (ORP). Applications for multiparameter meters include water testing, pharmaceuticals, agriculture, winemaking, water-treatment plants, and acquaculture. Devices with a benchtop body are often used for indoor laboratory use or in a manufacturing setting; handheld, portable devices are typically used for fieldwork. Sensors are used with a meter to measure the parameters of a substance.

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) 9001 standards.
