More than three decades have passed since the appearance of the first Lovibond PC 100 photometer system.
Since that time, Tintometer has become a world-famous name as the manufacturer of photometer systems sold under the brand name of Lovibond.

Our range of photometer systems extends from the MiniDirect in a pocket sized for- mat, CheckitDirect, MaxiDirect, to the SpectroDirect spectrophotometer. The multi-functional PoolDirect provides the answer to all requirements relating to the analysis of water used in modern swimming pools and baths.

The MultiDirect offers a wide variety of pre-programmed methods and is therefore suitable for the demands of modern water analysis.

	MD100 Precise Water Analysis in High Quality Design – Small, Mobile, Rapid
	MD200 Precise Water Analysis in High Quality Design – Small, Mobile, Rapid
	PoolDirect A flexible, multi-parameter photometer covering a wide range of tests for today´s water analysis requirements.
	PoolDirect 9in1 With single key parameter selection. Accurate Dual-Beam-Technology and Interference Filters.

The principle of photometry

When specific reagents are added, the water sample takes on a degree of coloration that is proportional to the concentration of the parameter being measured. The photometer measures this coloration.
When a light beam passes through the coloured sample, energy with a specific wavelength is absorbed by the test substance.

The photometer determines the coloration of the sample by measuring the transmission or absorption of light of this wavelength (in other words, monochromatic light). The photometer then uses a microprocessor to calculate the required concentration and displays the result.
