G e ne r a l De s c r i p ti o n
The ODORGAS is a hand-held digital gas detection instrument manufactured by QED
Environmental Systems Ltd. The intended use of the ODORGAS is to measure concentrations of
odorants in piped gas network applications.
The primary odorant measured is THT (Tetrahydrothiophene), the instrument is available with or
without an integral pump.
With an internal memory for data storage of up to 3,000 readings, size of 145 x 70 x 33 mm / 5.7
x 2.75 x 1.3 inches and a weight of 350g / 12.34 Oz, the ODORGAS is an excellent and convenient
instrument for measuring odorants.
ODORGAS has been certified with the intrinsic safety protection mode and has obtained the
following marking:
II 2G Ex ib d IIC T4 Gb

Switch On
Press the ON/OFF [1] button for 2
seconds, until the display is activated.
The start sequence includes several steps:
- Display check.
- Information about the firmware
version of the instrument, serial
number of the instrument and next
calibration date.
The instrument will warm up and calibrate
itself. This typically will take up to 30
seconds. The instrument’s functions are not
available during the warm up period.
Once the warm up and calibration are
complete, the two LED lights ●● [5] will
blink and the alarm will sound.
The ODORGAS is now ready for use.
Switch OFF
Press and hold the ON/OFF key for a few seconds.
A counter on the display will count down from 4 to 0 and the instrument will then power down.
You must hold the ON/OFF key for the duration of the count down.

The user will be prompted to save the
reading against an identification
number.
At the identification number prompt,
the digit ready to be altered will flash.
To change the number, use the scroll
key.
To move to the next number, use the
function key.
To store the reading, short-press the

RC-1 Adapter for high pressure & flow.
To ensure you achieve the most accurate readings possible from your device, the ideal sampling
conditions should be met (Between 150 – 300ml / 0.005 ft3 - 0.01 ft3 per minute flow & Less
than 0.4 bar / 5.8 PSI pressure). In the event of high sample pressure and flow (above 300ml /
0.01 ft3 per minute and over 0.4 bar / 5.8 PSI pressure) QED recommends using the RC-1
adapter to reduce your sample to a controlled level similar to the ideal window of operation.
Connect your RC-1 between your sample point and your Odorgas unit as per the diagrams
below:
