What Is a Light Meter? A light meter measures the amount of visible light, also known as illumination, in a given area. For many meter brands, including Extech, illumination is expressed in units of measure called Lux (for metric) and foot-candles (used in the US). To use an Extech light meter, the sensor is placed on a tabletop or other surface in the area to be measured and the light level reading is indicated on the meter's display. There are many different types of lighting that can be measured. the most common are: sodium, tungsten, mercury, and fluorescent. The following list shows common applications for each lighting type.Sodium lighting: Highway, parking lots, security measurementsTungsten lighting: Sunlight and incandescent lighting measurementsMercury lighting: Highways, parking lots, stadiumsFluorescent lighting: Indoor lighting for workstations and store display areas

Chlorine dioxide is used primarily as a disinfectant in drinking water and also in various industrial processes. In drinking water applications, it is gaining popularity over chlorine, considering that it does not generate trihalomethanes when reacting with organic compounds. In industrial applications, it is used as a bleaching agent in such applications as pulp and paper. The HI96738 meter measures the chlorine dioxide content in water samples in the 0.00 - 2.00 milligrams per liter range. This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell. Chlorine dioxide is a highly effective microbiocide that carries a number of important regulatory approvals from several international organizations including the US EPA, FDA and UK government for many of its uses. Chlorine and bromine react rapidly with microbiological species and chemicals in water. This reactivity is both their strength and weakness. Since chemical reactions are usually the first to take place, only the small residual of the product remaining after the chemical reaction is completed is available for microbiological control. Chlorine dioxide is a very safe and potent biocide. It is effective over a wide pH range in both hard and soft water and does not react with most other water treatment chemicals. HI96738 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.01 milligrams per liter resolution. +/-0.10 milligrams per liter +/-5 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 575nm light detector. 0 to 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Auto-off: after 10 minutes of non-use in measuring mode, after 1 hour of non-use in calibration mode. Measures 7.6" length by 4.1" width by 2.7" height. Chlorophenol red method.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96734C

The Hanna Instruments HI 96734C high range free and total chlorine portable photometer measures free and total chlorine content in water in the high 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 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. Free chlorine photometers measure the free and total chlorine content in water samples to monitor over chlorination through chloramine destruction. This meter is often used in surface sanitation, disinfection of medical devices, and in removal of microorganism infections in piping systems. Reagent is sold separately. Range is 0.00 to 10.00 mg/L. Accuracy is + or - 0.03 mg/L, + or - 3% of reading at 25 degrees C, excluding dilution error. Resolution is 0.01 mg/L (0.00 to 3.50 mg/L), and 0.10 mg/L (above 3.50 mg/L). Dimensions are 192 x 102 x 67 mm/7.6 x 4 x 2.6 inches (H x W x D), and the meter weighs 290 g (10 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 reagents (sold separately) and free chlorine in a sample causes a distinct pink color to appear, which is measured by the photometer. The meter uses an adaptation of the United States Environmental Protection Agency (USEPA) method 330.5 and standard method 4500-Cl G. Photometers measure the light intensity of solutions or surfaces. For solution testing, ...
