Perma Pure Direct Extractive Filter Probes

Baldwin's Direct Extractive Filter Probes feature an advanced design to extract sample gas and remove particulate while preventing condensation prior to the gas sample entering the heated sample line.

 Baldwin General Purpose Probe General Purpose Probes

Baldwin's new Sure-Lock filter assembly is precision machined and features a unique design to help ensure proper insertion into the assembly and to reduce the possibility of leaks. The filter head is inserted into a notch in the assembly to ensure proper alignment before locking it in place. The o-rings are tightened under compression, rather than being located on the sides of the filter head, to reduce the risk of leakage. Download brochure.
