• Portable combustible gas leak detector

Portable combustible gas leak detector

Short Description:

Portable combustible gas leak detector adopts ABS material, ergonomic design, easy to operate, using large screen dot matrix LCD display. The sensor uses the catalytic combustion type which is anti-interference capability, the detector is with a Long and flexible stainless goose neck detect probe and used to detect gas leak in the restricted space, when the gas concentration exceed a preset alarm level, it will make audible, vibration alarm. It is usually used in detecting gas leakage from the gas pipelines, gas valve, and other possible places, tunnel, municipal engineering, chemical industry, metallurgy, etc.

● Plug in the charger and the instrument will start automatically.
There are two different ranges of the instrument. The following is an example of a range of 0-100% LEL.

After starting up, the instrument displays the initialization interface, and after initialization, the main detection interface is displayed, as shown in figure 3.

Figure 3 Main Interface

Figure 3 Main Interface

The instrument testing near the location of the need to detect, the instrument will show detected density, when the density exceeds bid, instrument will sound alarm, and accompanied by vibration, the screen above the alarm icon0p appears, as shown in figure 4, the lights changed from green to orange or red, orange for first alarm, red for the secondary alarm.

3.5 Equipment calibration
When the instrument is used for a period of time, the zero drift appears and the measured value is inaccurate, the instrument needs to be calibrated. Calibration requires standard gas, if there is no standard gas, gas calibration cannot be performed.
To enter this menu, need to enter the password as shown in figure 12, which is 1111

Figure 12 Password input interface

Figure 12 Password input interface

After completing the password input, press  startingenter to the device calibration selection interface, as shown in Figure 13:

Select the action you want to take and press starting enter.

Zero calibration
Enter the menu to perform zero calibration in clean air or with 99.99% pure nitrogen. The prompt for determination of zero calibration is shown in Figure 14 .Confirm according to ▲.

Figure 14 Confirm the reset prompt

Figure 14 Confirm the reset prompt

Success will appear at the bottom of the screen. If the concentration is too high, the zero correction operation will fail.

Gas calibration

This operation is performed by connecting the standard gas connection flowmeter through a hose to the detected mouth of the instrument. Enter the gas calibration interface as shown in Figure 15, input the standard gas concentration.

Figure 15 Set the standard gas concentration

Figure 15 Set the standard gas concentration

The concentration of the input standard gas must be ≤ the range. Press  starting to enter the calibration waiting interface as shown in Figure 16 and enter the standard gas.

Figure 16 Calibration waiting interface

Figure 16 Calibration waiting interface

Automatic calibration will be executed after 1 minute, and the successful calibration display interface is shown in Figure 17.

Figure 17 Calibration success

Equipment maintenance

4.1Notes
1)When charging, please keep the instrument shutdown to save charging time. In addition, if switch on and charging, the sensor might be affected by the difference of charger (or the difference of charging environment), and in serious cases, the value might be inaccurate or even alarm.
2)It needs 3-5 hours for charging when the detector is auto-power off.
3)After get full charged, for combustible gas, it can work 12hours continuously (Except for alarm)
4)Avoid using the detector in a corrosive environment.
5)Avoid contacting with water.
6)Charge the battery every one to two-three months to protect its normal life if it is not used for a long time.
7)Please be sure to start the machine in normal environment. After starting, take it to the place where the gas is to be detected after the initialization completed.
