Detailed evaluation of BX616 multi-gas detector

The appearance of the grip is very fit and compact, perhaps because the inner suction pump is not integrated, so the machine size is reduced quite a bit. The grip is firm, not slippery.

As is the property of using a machine on the field, the machine is equipped with a plastic rubber impact-proof case
Front of the camera: The LCD display may seem a bit small, but if only to show the gas concentration and battery capacity, there is no problem. Because the gas detector is directly diffused, the front of the machine is arranged directly with 4 sensors to measure 4 types of LEL, O2, CO and H2S gases. The machine is also equipped with only 1 push button for all functions of the machine, which is relatively convenient when using gloves (working gloves) to avoid mistakenly pressing other buttons when using. The machine is equipped with 3 lights and 1 horn, when the lights are on and the alarm, can be seen almost from all directions.
Behind the machine there is only 1 clamp to set up the belt or chest pocket when using hands-free mode. In addition, the machine is equipped with a choke leg that combines a computer connection foot according to the mini USB standard, this type of connection is relatively convenient and common.

How to use the BX616 gas detector

Open the machine: Press and hold the power button until the screen is bright. Flashing lights, bright screens and machines begin the normal start process. To ensure the safest when using, the start-up process will be required to undergo a self-examination of the alarm features of the machine are lights, horns, vibrations, after which the sensors will auto zero (about 0).If during the start-up does not see the vibrator, the light is on and the siren, the machine has broken or disabled one of those features. Pay attention when the auto zero machine, because at this time, the machine will automatically take zero for the CO, H2S and LEL gas sensors and the 20.9% mark for oxygen gas, so to ensure accurate measurement, it is recommended to leave the auto zero in a clean air environment.
Normal operation: After starting in parallel, the machine will call for 1 hour “bip” to start the normal gas measurement process. During this time, the machine will occasionally shout “bip” to remind the user it is still active. If the air threshold is not up to the alarm level, the backlight, the indicator light are not on, users can press and release the button on the machine to turn on the backlight.
Shutdown: Shut down by pressing and holding the power button until the screen and horn are completely turned off.
Charging: Although the machine reaches the level of explosion room, it is mandatory for the gas detector to choke in a safe area.
