G-TECTA 4G Multi-Gas
®
Detection Instrument

Introduction

G-TECTA 4G 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.
G-TECTA 4G 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 4G 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
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.

Key Features

G-TECTA 4G has been designed to be a reliable
®
and robust personal monitoring system, whilst
being compact, light and easy to use. The
instrument is water and dust tight to IP65 and
IP67 ratings. The G-TECTA
design ensures high levels of user comfort and
minimal interference with the user's normal work
function. The non-slip grip and alligator clip ensure
secure handling and wear ability and additional
4G can be
®
4G's shape and
®
accessories such as shoulder straps and chest
harness allow flexible wearing options if desired.
The G-TECTA 4G has a single mode button and a
®
high quality display with automatic backlight. The
instrument continuously monitors the gas level in
the environment providing current, peak, and time
weighted average (TWA) readings for the user.
The G-TECTA 4G can be configured by utilising
®
Linde G-TECTA PC software. Data and event
®
logging can also be downloaded and managed
whilst the instrument is being charged via the
optional charger with communication link.

Software

The instrument software has been written in
accordance with IEC 61508 to ensure quality and
integrity in operation. The internal circuitry monitors
for any malfunction and will display an error
warning to the user in the unlikely event they occur.

Batteries

G-TECTA 4G is battery operated and is supplied
®
with a Lithium-Ion battery pack.
Battery Check
G-TECTA 4G should arrive with sufficient charge
®
so that the instrument can be used straight out the
box. However, to attain the full operating time you
should charge the battery. (The actual operating
time will depend on the types of sensor installed.)
The G-TECTA 4G will operate for at least 16 hours
®
on a fully charged battery.
WARNING
 Only recharge the rechargeable
battery in a safe (non-hazardous) area with a
Linde G-TECTA 4G charger. Failure to comply could
®
invalidate safety certification and may result in
permanent damage to the instrument.
