Description of unit
This contemporary, multi-parameter photo-meter caters for the full range of water testing requirements experienced by modern swimming pools. Various national laws and standards and international regulations make high demands on the practicability of the testing unit as well as on the accuracy of results.
Optics
Twin light-beam technology guarantees optimum precision with PoolDirect photometers.
With this system, the wavelength of a light beam is generated by an LED and fine-tuned through an interference filter. This light beam is then split via a semi-transparent mirror into a measurement beam and a reference beam.
The light intensity of these two beams is measured by two different detectors. The reference beam strikes the detector directly, while the measurement beam first passes through the sample, before it strikes the second detector.
The measurement figure is arrived at by calculating the difference in light intensity of the two beams and this means that only the absorption in the sample is measured. Any interference factors are automatically eliminated.
