The Gold Standard in Fume Hood Testing

The Q200 has a long history.  It was first made by Qualicheck and then by Uson.  Uson stopped production in 2015 and since then it has been made by D-Industrial in China.

​

D-Industrial has a long history with the Q200 first making it for Uson for the Chinese market.  Then buying full rights to the product.  Many of the potential improvements Uson could have made, were never made because of the planned discontinuance of the product.  But when D-Industrial purchased the rights, they decided to update the unit.  So a number of changes were made, but most significantly was the sampling pump.

​

The new units work even better than the older ones.  They are more responsive and have a greater degree of sensitivity.

​

If you like the older Q200 you will love the newer one. You owe it to yourself to give it a try. You will not be disappointed.
