Photometers for testing drinking, process and waste water
Microprocessor controlled photometer water quality testing kits designed to provide rapid, reliable and precise measurements of the most important water treatment parameters.
Applications: Water Treatment, Waste Water, Cooling/Boiler Water and Swimming Pools.
PCcompact 4 in 1 Photometer
 |
Microprocessor-controlled water quality testing photometer for testing Chlorine, pH, Cyanuric Acid and Total Alkalinity |
Wallace & Tiernan P15 Plus Photometer
 |
Microprocessor-controlled water quality testing photometer for testing Chlorine, pH, Total Alkalinity, ozone, chlorine dioxide, Bromine and Cyanuric Acid |
 |
The MD 100 uses high quality interference filters with long-life LEDs as a light source without any moving parts in a transparency sample chamber. The units supply accurate, reproducible results very quickly. Other major advantages include ease of operation, ergonomic design, compact dimensions and safe handling. |
MaxiDirect Photometer
 |
The MaxiDirect Photometer combines the mobility of a portable water quality tester with the characteristics of a modern laboratory photometer |
MultiDirect Photometer
 |
The MultiDirect is a microprocessor-controlled photometer with ergonomically designed keypad and large-format graphic display. It is equipped with a wide range of pre-programmed methods and allows for the user to store their own |
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.
