Hazardous Area Oxymitter 4000
A source of instrument air is optional at
the Hazardous Area Oxymitter 4000 for
reference air use. Since the unit can be
equipped with an in-place calibration fea-
ture, provisions can be made to perma-
nently connect calibration gas bottles to the
Hazardous Area Oxymitter 4000.
If the calibration gas bottles will be perma-
nently connected, a check valve is required
next to the calibration fittings on the integral
electronics.
This check valve is to prevent breathing of
the calibration gas line and subsequent flue
gas condensation and corrosion.
The check valve is in addition to the stop
valve in the calibration gas kit and solenoid
valves in the IMPS 4000 or SPS 4000.
NOTE
The integral electronics is rated NEMA
4X (IP66) and is capable of operation
at temperatures up to 85°C (185°F).
The optional LOI is also rated for
operation at temperatures up to 85°C
(185°F). The infrared keypad function-
ality will degrade at temperatures
above 70°C (158°F).
Retain the original packaging for the
Hazardous Area Oxymitter 4000, in
case the components are to be
shipped to another site. This packag-
ing is designed to protect the product.

IMPS 4000 (OPTIONAL)

If using an IMPS 4000 with a Hazardous Area
Oxymitter 4000, the IMPS 4000 sequencer must
be installed in a non-hazardous, explosive-free
environment.
For further IMPS 4000 information, refer to the
IMPS 4000 Intelligent Multiprobe Test Gas
Sequencer Instruction Bulletin.

SPS 4000 (OPTIONAL)

If using an SPS 4000 with a Hazardous Area
Oxymitter 4000, the SPS 4000 sequencer must
be installed in a non-hazardous, explosive-free
environment.
For further SPS 4000 information, refer to
the SPS 4000 Single Probe Autocalibration
Sequencer Instruction Bulletin.
