Visual Colorimeter, Lovibond® Tintometer Model F
- Individually housed glass colour standards
- Prismatic optical system for accurate and repeatable colour matching
- Standardised and diffused tungsten-halogen light source
- Replacement inserts simplify cleaning and maintain interior whiteness
The Model F is a versatile visual colorimeter for measuring the colour of liquids, solids, powders and pastes in terms of Lovibond units. The user simultaneously compares the colour of light that is either transmitted through or reflected from the sample with that transmitted through a series of glass colour filters in 3 primary colours - red, blue and yellow. The slides are adjusted until a visual colour match is found for the light from the sample and the colour is then expressed in Lovibond RYBN units....
Test papers, potassium iodide starch
This test paper allows the quick and easy detection of strong oxidizers such as nitrite and free chlorine. Potassium iodide starch paper is also used to control diazotization reactions. Nitrite or free chlorine oxidize potassium iodide to form elemental iodine which reacts with starch to a blue-violet complex. Potassium iodide starch paper may be used by dipping it into the sample or by applying drops of the sample onto the paper. To detect gaseous oxidizers, the paper is moistened with distilled water and then exposed to the gas in question....
Test papers, lead acetate
The test paper allows the quick and easy detection of hydrogen sulphide. This gas occurs in the processing of raw oil. It is toxic even in low concentrations. Therefore, critical points are carefully checked. Sulphide containing solutions also give a positive reaction. Lead acetate is toxic and the test paper needs to be declared as hazardous. The technically equivalent Sulphide test paper is a non-toxic and safe alternative....
Test Kits for Boiler-, Cooling- and Industrial Process Water
These test kits are specially developed for testing boiler, cooling and industrial process water. They make use of both colorimetric and titrimetric techniques. Each test kit contains all the necessary chemicals and reagents in liquid
or powder form to conduct the tests. The detailed instructions contain a step-by-step explanation of the test procedure. The kits are supplied in a sturdy, compact plastic case....
