Hanna Instruments HI96730 Molybdenum Portable Photometer with Sample Cuvettes, 7-19/32" Length x 4-3/32" Width x 2-11/16" Height, 0.0 - 40.0mg/L, 0.1mg/L Resolution, 9V Battery

The HI96730 measures the molybdenum content in water and wastewater. The 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. Whenever possible use the same cuvette for both. It is necessary that the surface of the cuvette is clean and not scratched to avoid interference due to unwanted reflection and absorption of light. It is recommended not to touch the cuvette walls with hands. Furthermore, in order to maintain the same conditions during the zeroing and the measuring phases, it is necessary to close the cuvette to prevent any contamination. HI96730 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.0 to 40.0 milligrams per liter pH range. 0.1 milligrams per liter pH resolution. +/-0.3 milligrams per liter +/-5 percent of reading at 25 degree C accuracy.
