That makes the application very quick for the end user. They are precalibrated and contain all necessary equipment and reagents. Precise The colour charts are adjusted and checked using certified standard solutions that are directly traceable to primary NIST standards. The user can be sure to receive accurate readings whenever he tests.
Test strips for assessing the fixing capacity of fixing baths pH and silver I ion concentration and for the detection and semi-quantitative determination of silver. The Fixing Bath Test provides a rapid method for establishing whether a fixing bath is still fresh enough to fix films and prints properly. It is also eminently suitable for checking continuous operation fixing equipment in which the silver I ion concentration is set to combine sufficient fixing capacity with a short fixing time. Performing a simultaneous pH determination provides an additional benefit in that a change in the pH value also signals that the bath is stale. Furthermore, the test can be used to monitor the recovery of silver from fixing baths. If the recovery system is functioning properly, silver should no longer be detectable.
Test strips are one of the easiest methods of testing water. Simply dip the strip in water, following the instructions and compare the color of the strip to determine the result. Use test strips when a general range is sufficient. Test strips should not be used when an exact measurement is required. With Hach Water Quality Test Strips, technicians in the field can test many samples in only a few minutes, and make immediate evaluations on-site.
