2 ABOUT THE DETECTION TAB
The Gas Detection Tablet is a unique detection method developed by our company. The tablet contains a
paper impregnated with special chemicals that will darken if exposed to a specific gas.
Proper storage of the tablet is critical. If tablet is not stored correctly, the detection results will not be
accurate.
2.1 Storage of Detection TAB
Follow the storage instructions on the detection TAB package. Detection tabs must be stored in a
refrigerator for longest life.
If detection tab is removed from its package and not used right away, it must be discarded. It will give
an incorrect reading if used later. Prolonged exposure to air or background gas will dry out the tablet or
cause it to become discolored, either of which will cause an incorrect reading.
2.2 Handling of Detection TAB
____ ___ Test paper (White) Ring (Black) TAB No & Gas name etc
Do not touch the test paper with your finger; this will cause an incorrect reading.
Detection TAB must be used within the storage period indicated on the package.
Use of tablets beyond their expiration date can result in incorrect readings.
Leave detection TAB in its package until ready for use. Once a tablet is removed
from its packet, it will begin drying out, and also it may respond to gas in the local
environment causing error if used for any actual test.
Do not touch the test paper of the detection TAB.
