**REQIURES BATTERY PUMP** Single add on analysis of an Air sample. To be used with the professional air test pump. (MICRO 5)
**See 2nd photo for type of pump required**
I still have not received the canisters I ordered. So I can't really give a review..
Had to call to request a link to order additional air testing cassettes. It would have been far more efficient if I was able to order without hunting around and then having to call and wait for a call back, etc.
In all other respects the price, shipping, speed, etc. all met my expectations.
