The HI 991404 pH/EC/TDS/temperature meter is a multi-parameter device for monitoring nutrient parameters in hydroponics, greenhouses, and horticultural applications.
Featuring a large easy-to-read LCD screen, automatic calibration and temperature compensation, the tester provides fast and accurate pH, electro-conductivity (EC), Total Dissolved Solids (TDS) and temperature readings. A self-check assures the device is in working condition, while the internal stability feature indicates when to take a reading. A hold function allows the user to freeze the display in order to record results. The HI 991404 also features a non-clogging double junction pH electrode and a conductivity probe.
The HI 991404 tester measures temperatures of 0.0 to 60.0 degrees C (32 to 140 degrees F) + or - 0.5 degrees C (+ or - 1 degrees F)/RH max 95% (+ or - 0.1 degrees C / 0.1 degrees F), and has a range of 0.0 to 14.0 pH (+ or - 0.1) with a resolution of 0.1 pH. EC range is 0 to 3999uS/cm (+ or - 2% F.S), with a resolution of 1uS/cm. TDS range is 0 to 2000pp(mg/L) (+ or - 2% F.S), with a resolution of 1ppm. The EC/TDS conversion factor is adjustable from 0.45 to 1.00. The device has an input impedance of 1E12 Ohm and operates on a 12 Vdc power adapter. The dimensions are 160 x 105 x 31 mm (6.3 x 4.1 x 1.2") and it weighs 190 g (6.7 oz.), a conveniently sized meter for taking measurements in the field. Note that the HI 991404 meter does not work with a digital ballast.
pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.
Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH pocket tester. To ensure the quality of their products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
