Frequently Asked Questions

What are check standards?

Check standards are used to determine if an instrument is still within calibration.

Photometers work by sending light through the sample, check standards for these instruments are usually either Coloured Solutions or Neutral Density Filters (NDF). Both types have known and certified transmittance or absorbance values so they should give these values when read in a photometer. To make the checking process even simpler some instruments will convert these to a parameter such as chlorine and give the value mg/L. The ‘target’ value is on the certificate supplied with the set of Check Standards.

Kemio and sensor instrument check standards verify that the instrument correctly measures electric signals. As with electrochemical sensors in samples, the instrument applies a voltage to the check standard and measures the resulting current. Check standards include verified resistors, which produce a consistent electric current. Kemio validates the measured current internally. Sensor instruments display the corresponding concentration value, which is compared manually to target values on the certificate supplied with the set of check standards. Check standard kits come with four standards to test across the measurement range.

Can I recalibrate my photometer using check standards?

Check standards allow you to confirm that your instrument is reading results correctly.

The recalibration process is a highly technical process which is carefully controlled. To recalibrate your instrument, it must be returned to Palintest. Contact your Palintest representative for more information.

What should I do if I get an unexpected result?

Palintest has a dedicated technical support team who is happy to assist you with any queries. To help speed up our response and to ensure we can deal with your query as quickly as possible, please provide as much information as you can (e.g. instrument serial number, some background information to your application). To contact them, please fill in the form on this page.

To help equip you with more information to get the best out of your instrument, our team has also created a library of information which can be found in our content hub. This includes a list of best practice tips to help ensure you are performing the test correctly, to view these tips please click here. 


What does ‘blank’ mean in the Palintest Test Instructions

‘Blanking’ is how a photometer sets the zero point when conducting a test. For the majority of tests, a blank is a sample of water to be tested, with no reagent added.

Some exceptions are Tubetests that usually require the blank to be a new unused Tubetest.  COD (Chemical Oxygen Demand) requires a Tubetest to be made into a ‘blank’ by adding deionised water and digesting (heating) it, following the sample process used for a sample.  These procedures are explained in the relevant test instructions.

What do I get in a Palintest photometer service?

An instrument service covers an initial visual evaluation, run of check standards, software check and upgrade if necessary. The instrument is then recalibrated and issued with a new certificate.
