The BTS 309 series of filter holder is designed to accept the Bird & Tole Card Mounted Filter so that the filter disk may be handled without touching the sampling area. Records of the sampling may be written on the card if so desired.
Salient points of the BTS 309 Filter Holder
· The card may be inserted and withdrawn from the filter holder without disconnecting
the vacuum line.
· The Filter Holder may be hard plumbed in any sampling line. The unit will seal without a card in
position so it therefore can be left in the line until required.
· The standard fitting on the up-stream end is a 1” BSP parallel thread for connection to a
standard valve. Other end fittings can be produced to order (see photo SP)
· The Filter Holder can be used as an open fronted unit if required.
· The BTS 309 Filter Holder can be manufactured in either lightweight aluminium alloy or robust
