Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96701C

The HI 96701C is an auto diagnostic, portable microprocessor meter that measures the free chlorine (Cl2) content in water samples. The CalCheck function validates instrument performance. The meter is splashproof and the lamp and filter units are protected from dust or dirt by a transparent cup, making it suitable for field applications. Messages on the LCD screen aid the user in routine operation and an auto-shut off feature turns the meter off automatically after 10 minutes of non-use in measurement mode or after one hour if left in calibration mode. The device uses an exclusive positive-locking system to help ensure the cuvette is in the same place every time it is placed into the measurement cell. It fits a cuvette with a larger neck, making it easier to add both sample and reagents. The reagent is in powder form and is supplied in packets, with amounts precisely dosed to help ensure accurate repeatability. Range is 0.00 to 5.00 mg/L + or – 0.03 mg/L + or – 3% of reading at 25 degrees C, with resolutions 0.01 mg/L from 0.00 to 3.50 mg/L; 0.10 mg/L above 3.50 mg/L. The device operates on a 9V battery. Dimensions are 192 x 104 x 69 mm (7.6” x 4.1” x 2.7’’), and weighs 360 g (12.7 oz). Free chlorine (Cl2) photometers measure the Cl2 content in water samples, which is an indication of whether sufficient chlorine is present to inactivate bacteria and protect the water from contamination during storage. They and are commonly used for drinking water.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96751

The Hanna Instruments HI 96751 sulfate portable photometer measures sulfate content in water, 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 nonuse in measurement mode, and after one hour of nonuse 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. Sulfate photometers measure the sulfate content in water samples, and are commonly used in the water quality and beverage production industries. Range is 0 to 150 mg/L. Accuracy is + or - 1 mg/L, + or - 5% of reading, with a resolution of 1 mg/L. Dimensions are 192 x 104 x 69 mm/7.6 x 4.1 x 2.7 inches (H x W x D), and the meter weighs 360 g (12.7 oz.). (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.) Power source is a 9V battery (included). A reaction between the reagent (sold separately) and sulfate in a sample causes a distinct white cloudiness to appear, which is measured by the photometer. The meter uses an adaptation of the turbidimetric 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 measure...
