APPLICATION OF ACCESSORIES

The probe incorporates a

Dust Filter, with replaceable

Disc, to prevent the ingress

of dust. A Water Filter

assembly (Part No. 42416),

complete with replaceable

hydrophobic filter is also

available as an accessory.
The Probe is connected to

the instrument via an 8-pin
DIN plug and sample line.
