The RECON is a portable-single gas detector for detection of combustible or toxic gases. It is intended for detection of
combustible or toxic gas in commercial or industrial facilities to keep workers safe, and/or detect a potentially explosive gas
environment.
The RECON, adopting excellent-quality sensor, makes detection in the way of natural diffusion. It has good sensitivity and
reproducibility. The detector adopts embedded MCU controller, easy to operate.
The RECON incorporates a special high strength, anti-slip rubber case providing anti slip handleability.
The RECON has an ingress protection rating of 65.

5.3 Battery Charging
When the battery voltage is low, the RECON will not function properly. To recharge the batteries of the RECON: The
RECON must be Off, connect the AC connector plugs of the charger to a 110VAC or 220VAC outlet and plug the charging
cable into the RECON. The detector will activate automatically and indicates that it is being charged. When the charging
cycle is completed, the display will indicate full charge.
W
ARNING
:
DO NOT start the battery
charge process with the RECON power on; otherwise the charge speed will be
adversely affected. Always charge the battery in normal ambient air. Do not charge the RECON in a hazardous
area to be monitored, to avoid fire or explosion. Disconnect the charger after 24 hours, failure to do so will
damage the battery.
Typical expected battery life and time to recharge:
RECON for CO, H2S, O2 30+ Hours, non-alarm condition: Recharge time: approximately 4 – 6 hours
RECON for %LEL CH4 8 hours, non-alarm condition: Recharge time: approximately 6 hours
N
OTE
: To maintain proper battery function and life the Recon should be operated once a week for 6 to 8 hours and then placed
on charge.
5.4 Sensor Replacement
Sensor life in the RECON is typically: 2 years for Carbon Monoxide & Hydrogen Sulfide and 1year for Oxygen and
Combustible.
The sensor needs to be replaced when the RECON can no longer be calibrated or if the sensor becomes erratic.
Contact ENMET for sensor replacement information.
