Hanna Instruments HI 98128W pH and Temperature Tester with Solutions for Wine
The Hanna Instruments HI 98128W is a hand-held pH and temperature meter with automatic calibration, a replaceable electrode, automatic temperature compensation, a stability indicator, and an LCD screen. The meter provides readings from -2.00 to 16.00 pH (+ or - 0.1), with a resolution of 0.01 pH. It is designed for wine and beverage making, but can be used for other applications.
The HI 98128W meter features automatic calibration with two sets of memorized buffers (pH 4.01/7.01/10.01 or pH 4.01/6.86/9.18), and automatic temperature compensation (ATC) for ease of use. An internal stability feature indicates when to take a reading, and a hold function allows the user to freeze the display to record results. The meter floats if dropped in liquid, and features a replaceable HI 73127 pH electrode to prolong the life of the meter. Four 1.5V batteries are included, and provide approximately 3,000 hours of continuous use.
The HI 98128W tester measures temperatures of -5 to 60 degrees C (23 to 140 degrees F), + or - 0.5 degrees C (+ or - 1 degree F) with maximum relative humidity (RH) of 100% with resolution 0.1 degrees C (0.1 degrees F), and has a range of -2.00 to 16.00 pH (+ or - 0.1) and resolution of 0.01 pH. Operating temperature range is -5 to 50 degrees C (23 to 122 degrees F). The meter measures 63 x 40 x 26 mm/6.4 x 1.6 x 1.0 inches (H x W x D) and weighs 100 g (3.5 oz.). (H is the vertical distance from lowest to highest point; W is the horizontal distance from left to right; D is the horizontal distance from front to back.)
pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.
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.
