MAINTENANCE AND CALIBRATION
Your ARJAY / ENMET gas detector is the state of the art in gas detection, but like any other
part of your ventilation system, it requires periodic maintenance and calibration.
There are various sensor technologies that may be used in your Arjay gas monitor; including
solid state MOS, Electrochemical, Infrared and Pellister Pair (Hot wire). These have a normal
operating life of 3 to 5 years under ambient conditions. You should consider a preventive
maintenance schedule whereby you test your system on a periodic basis to ensure its proper
calibration and operation.
For solid state (MOS) sensors, we recommend calibration every 3 to 4 months for a typical
garage application. For Electrochemical sensors, we recommend calibration every 6 months for
a typical garage application. Pellister Pair we recommend every 3 to 4 months and Infrared we
recommend every 6 months. For applications that are more sensitive, or where internal policies
exist, a higher frequency of calibration may be required. This is a simple procedure which will
indicate any problems with your system. A test and calibration kit may be purchased from
ARJAY ENGINEERING for this purpose. Parts are also readily available from our facility.
MAINTENANCE CONTRACT
Alternatively you may wish to consider a Maintenance Contract with ARJAY ENGINEERING
whereby one of our service technicians comes to your site and checks out the unit for proper
calibration and operation on a regularly scheduled basis. This is done on a flat per annum fee.
All parts are extra. Typical target gases are included, however, exotic or specialty gases may
have a surcharge. If you wish us to quote a Maintenance Contract fill in the section below and
return to our office.
