Overview
BH-90A-CO2 is a Portable single Gas detector launched by BOSEAN brand, dedicated to detecting carbon dioxide (CO2) gas. The product adopts mainstream 8-bit micro-control technology, with the characteristics of fast Response speed, high Measurement accuracy, Stability and Repeatability, and simple operation. Its body is compact, with IP65 protection level, high-strength ABS material shell, which can withstand the test of harsh environment. The instrument is equipped with sound, light and vibration three-level alarm, safe and reliable, and supports high and low alarm value settings.
Features
1. Industrial Sensor with High Sensitivity.
2. Adopt mainstream 8-bit micro-control technology.
3. The fuselage is compact and easy to operate.
4. With IP65 protection level, it is highly waterproof.
5. Long standby time, working continuously for more than 10 hours.
6. Support three-level alarm of sound, light and vibration.
7. High and low alarm values can be set.
8. Supports more than 30 types of Sensors, which can be flexibly configured or customized as needed.
Principle
The detector uses the diffusion Sampling method, and the gas enters the instrument through natural diffusion. The built-in industrial-grade Sensor (for CO2 gas) senses the gas concentration and transmits the signal to the 8-bit microcontroller for processing and calculation, and finally displays the real-time concentration value on the 1.77-inch high definition screen. When the concentration exceeds the preset high and low alarm values, the instrument will trigger sound, light and vibration alarms.
Applications
Industrial safety, environment monitoring, confined space operations, fire emergency, Petrochemicals, municipal pipe networks, warehousing and logistics, laboratories
Standards
GB3836.1-2010、GB3836.4-2010、GB15322.3-2003、JJG693-2011、JJG365-2008、JJG695-2003、JJG915-2008
Steps
1. Power on: Long press the power button to start the instrument.
2. Self-test: Sensor and system self-test will be automatically performed after the instrument is started.
3. Detection: Place the instrument in the environment to be tested and wait for the reading to stabilize.
4. View the data: Read the real-time gas concentration value through the display screen.
5. Alarm Response: When the instrument emits sound, light and vibration alarm, take immediate safety measures and evacuate.
6. Shutdown: Long press the power button to turn off the instrument.
7. Charging: When the power is insufficient, use the matching charger to charge the built-in lithium battery.
Notice
Please read the instructions carefully before use.
• Instruments need to be calibrated regularly to ensure detection accuracy.
• Do not use under conditions exceeding the Operating Ambient Temperature (-20~ 50 ℃) or Humidity (0~ 95% RH non-condensation).
• Avoid severe impact or falling of the instrument.
• Please use the original charger when charging, and the Charging time should be less than 5 hours.
• Sensors have a lifespan of about 2 years and need to be replaced in time when they expire.
When the instrument alarms, immediately confirm the safety of the environment and take corresponding measures.
• The explosion-proof mark of this instrument is Exib IIB T3 Gb, please use it in the specified explosion-proof environment.
• The instrument does not have Data storage function, but can record 1000 sets of alarm records.
