The Association cooperates with producers of normobaric devices. Our partners are companies offering devices that have been verified by the Association regarding the parameters of the atmosphere. They have proven that the atmosphere inside their devices complies with all the regulations formulated in the Good Practice of Normobaric Chambers and have received a certificate confirming this fact. The users of those devices can be sure that the conditions inside are in accordance with the formula created by the inventor of normobaria – Doktor Pokrywka.
