Clip-On UV Light Pen uses new solid-state LED technology to offer a portable source of UV light built into a slim attractive writing ballpoint ink pen. This new technology has a number of significant advantages over older products using UV fluorescent tubes and light bulbs. A more compact, rugged, and easily portable product, perfect for fieldwork, the 400 nm output is just on the edge of the visible light spectrum, low enough to cause fluorescence yet inherently safer than lower UV wavelengths. Much longer battery life eliminates the need for power cords and battery packs. Powered by only four button cell batteries (included). Immediate output, no warm up time. Dimensions: 5â…›" x â…œ" (130 x 9.5 mm) Weight: 1 oz (28 g) .

User calibration. Certified calibration and verification standards. BEPS (battery error prevention system). Timer function. Auto shut-off. GLP Features. Nickel is commonly utilized by the electroplating industry in processes utilizing stainless steel, cobalt or nickel alloys. Nickel is also used in batteries, fuel cells and hydrogenation of vegetable oils in the food industry. The HI 96740 meter measures the nickel content in water and wastewater. 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. The cuvette has a very important role because it is an optical element and thus requires particular attention. It is important that both, the measurement and the calibration (zeroing) cuvettes, are optically identical to provide the same measurement conditions. Supplied with sample cuvettes with caps (2), 9V battery and instruction manual. Range: 0.000 to 1.000 milligrams per liter. Resolution: 0.001 milligrams per liter. Accuracy: +/-0.010 milligrams per liter +/-7 percent of reading at 25 degree C. Light source: tungsten lamp. Light detection: silicon photocell with narrow band interference filter at 575 nm. Battery type / life: 1 x 9V / approx. 40 hours of continuous use; auto-off after 10 minutes of non use. Environment: 0 to 50 degree C (32 to 122 Degree F); RH max 95 percent non-condensing. Measures 7-19/32" length by 4-3/32" width by 2-11/16" height. Method: adaptation of the PAN method.
