1. The use and principal of application
1.1. SNIFFER 430 system (System) is used to pinpoint leaks in pipes or vessels by
the tracer gas (a mixture of 95 % nitrogen and 5% hydrogen gas) technique.
SNIFFER 430 system consists of a measurement Device and a wireless
hydrogen H2 Sensor (Figures 1-2) used to detect and measure hydrogen gas
concentration in the air. SNIFFER 430 is specifically useful for detection of
small leaks in underground and underfloor water lines.
1.2. The principle of operation is based on injection of tracer gas under pressure
into an inspected piping or vessel, followed by step-by-step search for the
area where the tracer gas is escaping. Tracer gas presence is detected by the
H2 Sensor, which transfers gas readings wirelessly (Bluetooth) into Device.
The Device converts the readings into Parts Per Million (PPM) H2values and
graphically presents them to the user. The area where the maximum PPM
values were observed, in most cases, corresponds to the leak position.
However, in some cases, such as underfloor jacketed pipes or pipes that are
partially underlying beneath soil and concrete slab, the actual position of
leaks can be located at some distance from the area where maximum PPM
levels were measured.

5. Operation
5.1. Switch on Device and H2 Sensor in an area where no traces of H2gas are
present. Device On/Off button is located on the top edge of Device (Figure
4). The H2 Sensor On/Off button is located on the top edge of H2 Sensor
(Figure 4).
5.2. Once Device detects the wireless H2 Sensor, the SENSOR CONNECTED
button will be shown in blue color (Figure 5).
5.3. Switch on H2 Sensor pump using the PUMP button (Figure 5) on Device
screen.
5.4. After the H2 Sensor is switched on, initial heating of the sensor is
performed (the system cannot be used during the heat up time). Once the
H2 Sensor is available for work a beep sound begins.
Note: Please note that initial values of PPM may be above zero due to different factors
such as air humidity or traces of gas trapped inside of the sensor from the previous use. In
such a case, the user can wait several more minutes with the H2 Sensor pump switched
on, until the PPM value will drops to zero. We recommend always keep the pump working
to allow fast air circulation through H2 Sensor. Even if the initial PPM values are above zero
for any reason, it does not limit or prevent performing a leak detection.
5.5. Stream tracer gas under pressure into piping or vessel after closing all
valves and openings which gas can escape through.
5.6. Walk slowly along the pipe or vessels, while directing H2 Sensor towards
the examined structure.
5.7. When H2 gas is detected, PPM value will rise. Walk around the area where
gas is detected to establish where PPM values are the highest. Take PPM
readings using TAKE A READING button (Figure 5) to assist in finding the
area with the highest PPM readings. This area may have the highest
probability of leak (but not always).
5.8. Push on the speaker button (Figure 5) to switch on/off beeping sound used
to assist in leak detection.
5.9. Adjust the brightness of the screen using + and – buttons (Figure 5).
5.10. Clear reading in the reading graph by pressing CLEAR button (Figure 5).
5.11. At the end of the work, switch off the device using the Device On/Off
button on the screen (Figure 5) and wait until the screen switches off.
Switch off H2 Sensor by pressing a Switch On/Off button (Figure 4).
5.12. Clean Sensor filter from large particles using a brush if needed.

6. Troubleshooting
Problem
Solution
1
Device do not detect the H2
Sensor
Check if H2 Sensor is switched on
2
Gas readings are reducing too
slow after exposure to tracer gas
Sensor air outlet (small opening on the
top edge of H2 Sensor, see Figure 4) is
blocked. Use a small diameter wire to
clean the opening. Contact service if it
does not solve the problem
3
Device shows non-zero value
when switched on
Turn on the pump on H2 Sensor and
wait until PPM values drop
4
Device does not switch on (no
blue light on the switch button)
Press the reset button located on the
left side of the power jack inlet located
the device's top edge (Figure 4)
