Photometers should be regularly cleaned to ensure that your instrument is reading correctly and is not affected by dust or watermarks.
To clean a compact photometer, place a small amount of anti-static cleaning foam on to a lint-free cloth and wipe the instrument.
For multiparameter photometers, you should clean several parts of your instrument. To clean, place a small amount of anti-static cleaning foam on to a lint-free cloth and wipe the instrument.
The first image shows the surface around the sample holder, all visible marks on this area should be removed.
|Outside optics base plate
Turn the instrument over and undo the two screws on the base of the instrument, as demonstrated in the second image. Gently wipe the curved areas near the LEDs and the flat area on the opposite side.
|Inside optics base plate
Contamination on the inside of the base plate can migrate onto your calibration tubes leading to scratches which may damage the standards. If marks cannot be removed from the base plate, a new base plate should be fitted. When refitting or replacing a base plate, you must ensure screws are tightened so that the standards are set are the correct height. Failure to do so can lead to compromised results.
How do I check my readings are OK?
Check standards allow you to confirm that your instrument is reading results correctly.
If the instrument requires recalibration this is a highly technical process which is carefully controlled by Palintest. To recalibrate your instrument, it must be returned to Camlab for more information on how to do this contact email@example.com. For technical enquiries please contact firstname.lastname@example.org.
