Key Features
- Hydrogen selective catalytic bead sensor technology for long life
- Industry standard linear 4/20 mA output
- Corrosion, weather and chemical resistant polycarbonate sensor enclosure
- Intelligent-design enclosure temperature control for improved cell life
- Sensor designed to adapt to any harsh environment from -40°F to +120°F
- Real-time continuous monitoring for early detection of explosive concentrations.
- Detectable range: 0-1% (10,000 ppm or 25% LEL)
- Absolutely no Zero drift compared to other catalytic bead type sensors
The GasGuard H2-1% utilizes
hydrogen selective catalytic bead
sensor technology for fast and
accurate detection. The standard
detection range provides real-time
continuous monitoring of hydrogen
concentrations accurately down to
500 ppm, with no false alarms.
The intelligent internal temperature
control of the GasGuard H2-1%
provides optimum temperature control
for extended cell life. The high-quality
injection-molded polycarbonate
enclosure offers excellent chemical
corrosion protection and high impact
resistance.
The GasGuard H2-1% provides
an industry standard linear 4/20
mA output signal compatible with
most gas detection systems and
PLCs. The output signal is not
affected by drastic temperature
variations or other atmospheric
conditions.
Applications
- Battery Charging Rooms
- Steel industry
- Refineries
- Perimeter Monitoring
- Heat treatment
- Sea Vessels
Benefits
- Simple operation
- Rugged and reliable
- Energy savings
- Long-life sensor
The International Fire Code section 608.6.1
states “the ventilation system shall be
designed to limit the maximum concentration
of hydrogen to 1% (25%LEL) of the total
volume of the room” or “continuous
ventilation shall be provided at a rate of not
less than 1 cfm per square foot of floor area
in the room”.
When using the GasGuard H2-1% in
combination with any of our GasGuardian
controller line (or any other 4/20 mA input
device), exhaust fan activation will prevent
dangerous accumulation of explosive
hydrogen gas concentrations. Since
continuous ventilation in refrigerated areas
can add up to huge costs, activating exhaust
fans only when necessary can amount to
thousands of dollars a year in energy savings
for your company.
Every circuit board is sealed forever in
potting compound, protecting electronic
components and copper tracing from
corrosion. A specially vented chemical-
resistant polycarbonate enclosure protects
the sensor from accidental damage, weather
and direct hose-hits from clean-up crews.
