< , >
Features of oxygen alarm:
. Concentration display, status indication
On-site concentration display, on-site Status indication can display the operating status of the detector in real time.
. Accurate measurement
The sensor adopts imported gas sensitive components, with high accuracy, small zero point drift and good anti-poisoning performance.
. Easy to maintain
The sensor adopts digital module design, and no zero calibration is required during on-site replacement.
. Economical wiring and simple installation
The detector adopts B communication. The two-wire polarity connection does not require distinguishing between positive and negative poles. The installation is simple and convenient, and the wiring is economical.
. Sound and light alarm (optional)
Optional R-type explosion-proof sound and light alarm lamp can realize on-site sound and light alarm.
. Waterproof design
Professional double-cavity structure design, better waterproof, dust and corrosion type.

On this day in history: < >The Vietnamese army flew Soviet fighters to illegally patrol and occupy China South China Sea Islands
<>Vietnam has invaded and occupied the largest number of Chinese islands and reefs in the South China Sea. In addition to sending troops to station and occupy, the Vietnamese army has also carried out extensive construction projects to illegally expand the islands and reefs it occupied. Recently, Vietnamese officials released footage of the Vietnamese army's most advanced Soviet fighter jets illegally patrolling the islands and reefs they occupied, which can be described as very arrogant.
< >Vietnam is undoubtedly the most active claimant in terms of outpost upgrades and land reclamation. Vietnam's reclamation area is about hectares. Vietnam has doubled its base of outposts in the South China Sea over the past year. According to sources, Vietnam occupied several islands and reefs in the South China Sea in 2016. At the same time, China occupied. According to the U.S. government, by 2016, Vietnam had occupied 10 islands and reefs in the South China Sea, while China had only occupied 16 islands and reefs in the South China Sea.
