Product Description

The Hanna Instruments HI 96750C potassium portable photometer measures potassium content in water in the low and medium range, has a calibration check function, automatic shutoff, an LCD screen, and on-screen instructions. The calibration check function (CalCheck) validates instrument performance. An automatic shutoff feature turns the meter off after 10 minutes of non-use in measurement mode, and after one hour of non-use in calibration mode, to help extend the life of the meter. Automated instructions on the LCD screen aid in routine operation. The meter is splashproof, and the lamp and filter are protected from dust and dirt by a transparent cup, making it suitable for field applications. The device uses a positive-locking system to help ensure consistent positioning of the cuvette. Potassium photometers measure potassium content in drinking and surface water samples, and are commonly used in the water quality, horticultural, and agricultural industries.

*Overall Dimensions	192 x 104 x 69 mm/7.6 x 4.1 x 2.7 inches (H x W x D)

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Power source is a 9V battery (included). A reaction between the reagent (sold separately) and potassium in a sample causes a distinct white cloudiness to appear, which is measured by the photometer. The meter uses the tetraphenylborate method.

Photometers measure the light intensity of solutions or surfaces. For solution testing, a sample and reagent are placed in a cuvette in the photometer. The photometer transmits light through the cuvette, and compares the intensity of the light that shines through to the amount of light that shines through a blank cuvette. The meter uses the difference to calculate the concentration of the test element. For surface testing, a surface is illuminated with white light, and the photometer measures the luminosity of the reflected light. Photometers are commonly used in water quality, agricultural, horticultural, and industrial applications to measure the amount of minerals and chemicals in samples, and for checking water and beverages, such as beer and wine, for consistency.
