Palintest calibrate photometers using certified colour standards that are traceable back to National Physical Laboratory (NPL) standards.
The certified standards are prepared by our Quality Control team in our modern laboratory facilities using traceable chemicals, externally calibrated balances and produced in small batches. This ensures the traceability chain is maintained throughout the production process.
The standards are then characterised by transmittance (% T) at a particular wavelength using an externally calibrated dual-beam spectrophotometer. The spectrophotometer is calibrated using the NPL standards.
During the manufacturing of photometers, the instruments are calibrated to read the correct %T at the wavelengths available on that particular photometer. The method of calibrating our photometers using the certified traceable standards forms part of the ISO 9001 business management system within Palintest and thus is fully audited.
Palintest offer check standards for the complete photometer range. These standards are manufactured in the same way as calibration standards and are therefore traceable in the same manner.
The check standards allow users in the field to verify their photometer is still conforming to our calibration specification. They do not recalibrate the photometer, merely give confidence that the photometer is still within specification and fit for purpose.

In this webinar we review the basics of pool and spa chemistry, including water balance and what is required to reopen your facilities. Starting with why you need to test your pool or spa, we then cover the key test parameters, frequency of testing, suitable test methods and tips for getting the best results.
