Typical modes of instrument support/handling include:
•
Hand-held. Do not obstruct or cover the sensing chamber opening slots on front
and back of unit.
•
Belt attached. Use belt clip provided as standard accessory. The unit can be worn
on a waist belt, or with optional shoulder belt (model
p
DR-SS) for breathing
zone monitoring.
•
Tabletop operation. The
p
DR-1000AN can be placed on a table either in an
upright position (i.e., resting on its lower protective bumper), or on its back (i.e.,
resting on the rear edges of its two protective bumpers).
•
Tripod mounted. The unit can be attached to any standard tripod using the
threaded bushing on the bottom of the monitor (see Figure 3).
•
Fixed point operation. The model
p
DR-1000AN can be mounted at a fixed
location (e.g., wall or post) using the optional wall-mounting bracket, model
p
DR-WB.
3.3.2
Model
pDR-1200
The
p
DR-1200 requires an external vacuum pump, such as a small diaphragm pump
(e.g., model
p
DR-PU) for its sampling operation. The inlet of the pump must be
connected by means of tubing to the hose fitting on the
p
DR-1200 37-mm filter
holder attached to sensing chamber (see Figure 2).
The inlet metal tube of the cyclone can be oriented in any desired direction (i.e.,
upward, forward, downward or backward) by rotating the cyclone body within its
holder cup on the right side of the sensing chamber (see Figure 2).
Always ensure unobstructed access to the cyclone inlet when sampling directly the
air in the instrument's vicinity. Alternatively, tubing can be connected to the
cyclone inlet in order to extract a sample stream from a duct, chamber or other
enclosed volume.
Typical modes of instrument support/handling include:
•
Hand-held. For example, using a personal type pump, clipped to the belt and
using a tubing connection to the
p
DR-1200.
•
Belt attached. Use belt clip kit provided as standard accessory. The unit can be
worn on a waist belt, or with the optional shoulder belt (model
p
DR-SS) for
breathing zone monitoring. A personal pump can then be belt-worn as well.
•
Tabletop operation. The
p
DR-1200 can be placed on a table either in an upright
position (i.e. resting on its lower protective bumper), or on its back (i.e. resting
on its backside).
•
Wall mounted for fixed point monitoring. Use optional wall mounting bracket,
model
p
DR-WB, either in combination with model
p
DR-PU pump module and
model
p
DR-AC power supply (powering both the
p
DR-1200 and the
p
DR-PU),
or with a separate pump.
