to EN50270 has been certified by 3C Test Ltd.
5. Repair of this equipment and gas sensor
replacement shall be carried out by the
manufacturer or approved service centre in
accordance with the applicable code of practice.
6. If the equipment is likely to come into contact
with aggressive substances, then it is the
responsibility of the user to take suitable
precautions that prevent it from being adversely
affected, thus ensuring that the type of
protection is not compromised.
7. The rechargeable battery must only be charged
in non-hazardous (safe) areas by connection
to the specified Linde charger. Rechargeable
batteries can only be replaced by a Linde Group
Authorised Service Centre.
8. Only the following battery types may be fitted
in the battery compartment of the replaceable
battery pack: Duracell MN1500 (LR6), Varta

must only be changed in a non-hazardous (safe)
area. Users can only change non rechargeable
batteries in G-TECTA® 4GP instruments.
9. The equipment is not certified for use in
atmospheres containing more than 21% Oxygen.
Area Classifications:
Zone 1: An area classified as Zone 1 is likely to have
ignitable concentrations of flammable gases, vapours
or liquids present under normal operating conditions.
Zone 2: An area classified as Zone 2 is not likely to have
ignitable concentrations of flammable gases, vapours or
liquids present under normal operating conditions.
G-TECTA® 4GP Portable Multi-Gas
Detection Instrument
Introduction
G-TECTA® 4GP is a premium, portable Multi-Gas
Detection Instrument, designed to be carried or
worn by individuals working in potentially hazardous
environments such as confined spaces. The
instrument is available with an internal pump or as a
diffusion only instrument. G-TECTA® 4GP is certified
for use in classified hazardous areas and monitors
up to four different gases by displaying the readings
simultaneously on the instrument screen. Alarm
warnings are transmitted by means of a loud audible
alarm, a bright visual alarm of blue/red flashing LEDs
and an internal vibrating alarm.
Sensors
G-TECTA® 4GP can be specified with a wide range
of intelligent gas sensors. The sensor is fitted to
an intelligent processor which contains calibration
and sensor information. The G-TECTA® 4GP can be
reconfigured at any time by replacing the pre-
calibrated intelligent sensor(s) with alternative gas
types. Sensors should be replaced by trained service
personnel and are easy to fit using “plug and play”
technology. The intelligent sensor(s) are immediately
recognised by the instrument and are ready to use
after instrument calibration.
