G-TECTA SG Premium
®
Single Gas Detection Instrument

Introduction

G-TECTA SG is a Premium Single Gas Detection
®
Instrument, designed to be carried or worn by
individuals working in potentially hazardous
environments. G-TECTA
classified hazardous areas and monitors a single gas
by displaying a reading 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 SG 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 SG can be reconfigured at any time by
®
replacing the pre-calibrated intelligent sensor with
an alternative gas type. Sensors should be replaced
by trained service personnel and are easy to fit
using "plug and play" technology. The intelligent
sensor is immediately recognised by
the instrument and is ready to use after
instrument calibration.

Key Features

G-TECTA SG has been designed to be a reliable
®
and robust personal monitoring system, whilst
being small, light and easy to use. The instrument
is water and dust tight to IP65 and IP67 ratings. The
G-TECTA SG's shape and 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 accessories such as shoulder
straps and chest harness allow flexible wearing
options if desired.
The G-TECTA SG 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.
SG is certified for use in
®
The G-TECTA SG 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 SG is battery operated and is available
®
with the option of rechargeable batteries or
replaceable alkaline batteries*
Battery Check
The G-TECTA SG has two battery options: Li-ion
®
rechargeable or non-rechargeable batteries.
Rechargeable Units
G-TECTA SG uses a Li-ion battery pack and should
®
arrive with sufficient charge so that the unit 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 flammable G-TECTA
will operate for at least 12 hours on a fully
charged battery.
WARNING
 Rechargeable units
Only recharge the battery in a safe (non-hazardous)
area with a Linde G-TECTA
comply could invalidate safety certification and may
result in permanent damage to the instrument.
WARNING
 Non-rechargeable Units
G-TECTA SG uses a CR2477 battery. To maintain
®
compliance with instrument certification, ensure
only the following battery types are used:
Panasonic, GP, Energiser, and Maxell.
