Product Details
GMV-2021B Gas Sensor For Hydrogen Production Workshops Hydrogen
Storage Tank Farms
Product Traits:
- All - Solid - State Structure: Adopts an all - solid - state
design, being lightweight, and it has great stability and
reliability .
- Low - Power & Long - Lasting: Features low power consumption, which
is beneficial for battery - driven devices; The service life is
long, reducing the frequency of device replacement .
- Good Anti - interference: Has remarkable anti - interference
ability, being able to avoid the interference from reducing gases
like alcohols, methane and carbon monoxide, which guarantees
detection accuracy .
- Quick Reaction: Can detect hydrogen as low as 1ppm or even in ppb
level, and the response time is within 10 seconds, which can
promptly discover slight hydrogen leakage .
- Good - quality Output: Has temperature compensation, and offers
linear output; Comes with output forms including serial port (UART)
and PWM waveform, which is convenient for connection with various
control systems .
Application Areas:
- Applied to hydrogen - fuel - cell cars, to detect hydrogen leakage
inside and around the vehicle fuel cell system .
- Used in hydrogen production workshops, hydrogen storage tank farms,
and hydrogen - powered charging stations, which is for ensuring the
safety of hydrogen energy storage and delivery by monitoring
hydrogen gas concentration .
- Suitable for other situations where hydrogen concentration
detection is required, such as in some hydrogen - involved chemical
reaction apparatuses .
