Using the Strap
The instrument's elastic strap allows the unit to be either hand-held, or
hung on nearby objects.
By sliding your hand between the instrument and its elastic strap, you
can hold onto the Oxor II with a minimum of effort. The instrument's
front panel slide switches can then be actuated by your thumb for one-
handed operation. Or, by releasing the metal clip at the bottom of the
instrument's case, you can hang the instrument by its strap on nearby
objects such as nails, sheet metal, or valve handles.

Using the Probe
The basic probe, or the optional rigid stainless steel probe with handle,
connected to a flexible hose with sample filter can be used to draw a
gas sample into the instrument from the room, grilles, diffusers,
furnace flues, hot-water heater flues, and from inside furnaces heat
exchangers.
Both hose and probe are detachable from the instrument when sam-
pling without the probe, or when sampling with a different probe is
desired.
Important: If condensation is observed within the hose, do not allow
water level to build up to a point where it cuts off flow.
