If there is moisture under the display of an HQd can this be repaired?
Moisture under the display of an HQd meter
Moisture under the display under normal operating conditions could mean that the gasket has failed. If use of the meter is immediately required, it may be helpful to first try to dry the moisture out in a desiccator. Failure to correct this condition will result in meter failure. Please contact Hach Technical Support to initiate this repair.
