Product Description
The Hanna Instruments HI 991003 is a waterproof, portable pH, pH-mV, oxygen reduction potential (ORP)/mV, and temperature meter used in water treatment applications with Automatic Temperature Compensation (ATC), automatic calibration at one or two points, a multilevel LCD screen, a pre-amplified pH/ORP probe with internal temperature sensor, and a battery error prevention system. A pH meter is commonly used to measure the pH of substance such as water, food, beer, or wine in laboratory, industrial, and food applications. An ORP meter, also known as a redox potential tester, measures the oxidization or reduction capacity of a solution, and monitors chemical reactions and ion activity. The multilevel LCD screen simultaneously displays the current measurement, the current temperature, and tutorial messages. This meter has ATC from -5.0 to 105.0 degrees C (23.0 to 221.0 degrees F) for accurate readings in fluctuating temperatures. The meter also has automatic one-or two-point calibration with two sets of memorized buffers: standard (4.01, 7.01, and 10.01) or National Institute of Standards and Technology (NIST) (4.01, 6.86, and 9.18).
The meter comes with the HI 1297D pre-amplified pH/ORP electrode with internal temperature sensor, titanium cage body, single cloth-junction to reduce contamination, gel electrolyte for fast response, 7-pin Deutsches Institut fr Normung (DIN) connector for a tight cable connection, and 1 m (3.3') cable. The meter uses three 1.5V AAA batteries (included) for up to 1200 hours of continuous operation and can be set to turn off automatically after eight minutes of non-use to extend battery life. The battery error prevention system alerts when battery power is low and displays battery percentage on startup. The operating temperature is from 0 to 50 degrees C (32 to 122 degrees F) with a relative humidity of 100 percent. The dimensions are 152 x 58 x 30mm/6.0 x 2.3 x 1.2 inches (H x W x D). (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The meter weighs 205g/7.2oz.The HI 991003 portable meter also comes with buffer solution sachets, electrode cleaning sachets, a carrying case, and instructions.
