Features

• The sensor detects the pressure fluctuation difference in the mask and displays the judgment result by the proprietary algorithm.
• Ideal for daily management and supervision of safety managers. Not only can the manager check whether the mask is worn correctly, but the wearer can understand the proper wearing condition by daily checking, and "make it a habit" and "make it stick."
• The measurement time is only 30 seconds! You can easily check "anytime," "anywhere," or "anyone." Veterans and inexperienced workers can *** this product without difficulty.
• As long as you have the space of a paperback book, you're good to go. Small and lightweight portable model. It only weighs 300 grams and is compact enough to carry in a special pouch. You can check the mask fit even in the field that changes regularly or in the place of secondment or space saving.
• Can be ***d continuously with dry battery (AAA) for about 3 months/6 hours per day.
