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.

Nitrates are present in nature as a result of decomposition of organic microorganisms or due to their use as fertilizers. Nitrates reduce to nitrites, which in turn easily combine to form substances dangerous to man. A maximum level of 45 milligrams per liter is established as a worldwide guideline for nitrate concentration in water. In Europe, the maximum consented level of nitrates in potable water is 50.0 milligrams per liter , while in the USA the EPA has established a guideline for the maximum level of nitrate nitrogen of 10 milligrams per liter (NO-3-N), which corresponds to 45.0 milligrams per liter of nitrates. The kit provides you with all you need for field measurement: photometer, reagents and apparatus perfectly fitted in a rugged carrying case. With a normal 9V battery you will be able to get more than 300 measurements. The auto shut-off feature (after 10 minutes of non-use) guarantees a long battery life. Range: 0.0 to 100 milligrams per liter . Resolution: 1 milligrams per liter . Accuracy:+/-5 milligrams per liter +/-5 percent of reading at 25 degree C. Light source: Tungsten Lamp.

Total hardness, that is the presence of magnesium and calcium, is due mainly to the runoff water dissolving these salts as it flows or filters through different strata. Hardness can also cause scaling of pipes in cooling and heating systems. The HI93735 measures the total hardness in drinking, surface and wastewater. This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit cuvettes with a larger neck making it easier to add both sample and reagents. The cuvettes are made from special optical glass to obtain best results. HI96735 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. LR 0 - 250 milligrams per liter; MR 200 to 500 milligrams per liter; HR 400 to 750 milligrams per liter range. 1.0 milligrams per liter from 1 to 100 milligrams per liter; 5.0 milligrams per liter from 100 to 750 milligrams per liter resolution. LR +/-5 milligrams per liter +/-4 percent of reading at 25 degree C; MR +/-7 milligrams per liter +/-3 percent of reading at 25 degree C; HR +/-10 milligrams per liter +/-2 percent of reading at 25 degree C accuracy. Light emitting diode. Silicon photocell with narrow band interference filter at 466nm light detector.
