calibration levels.

Proactive maintenance:

All gas detectors including both for flammable and toxic gases should have to pass a functional
test and calibration every three to twelve months according to EN 60079-29-2 industrial

Operational Life:

standards. The test results and calibration reports should be recorded in maintenance books.
Catalytic flammable gas sensor made by using the pellistors that suffer from a loss of
sensitivity when in the presence of poisons or inhibitors, e.g. silicones, sulphides, chlorine,
lead or halogenated hydrocarbons. The pellistors are poison resistant to maximize the
operational life of the Catalytic flammable sensor. A typical operating life, subject to the
presence of poisons/inhibitors is 48-60 months. The infrared flammable gas sensor is not
affected by the mentioned poisons and has a longer life span.
Typical life of a toxic gas sensor which made by electrochemical component is dependent on
the application, frequency and amount of gas exposure. Under normal conditions (visual
inspection in 3 months period and test/recalibration in 6 months period), the Prosense

Servicing

Oxygen and other toxic sensors have an expected life equal to or greater than 24 months.
Important: All replacement actions (sensor, sinter, and sensor head) shall be done by
Prosense trained service personnel as servicing needs special steps that should be performed

Battery

according to device technical characteristics.
Detector main board includes a battery (3.3V, 10mA). The purpose is to keep event logs and
recorded values during the life time of the detector and prevent data loss in case of power
outage. Battery does not have any function on performing detector functions and not
providing power to detector.
Do not remove or replace the battery!
