Why are the results lower than expected on my 3M Measuring Instruments?
- TTimothy WyattSep 3, 2025
If the results are lower than expected on your 3M Clean?Trace Measuring Instruments, it could be due to a sample or reagent problem. Check with a new 3M Clean?Trace Test and known positive samples, such as a 3M™ Clean-Trace™ Surface Positive Control or 3M™ Clean-Trace™ Water Positive Control. If this doesn't solve the issue, it may be an instrument malfunction. In this case, contact 3M or your local distributor.
