Thông tin sản phẩm

Characteristics

Carbon Monoxide is a colorless, odorless, tasteless and highly toxic gas. It will reduce the oxygen in body's hemoglobin and cause damage to the brain. Our QA23 is equipped with a precise and low power-consumption sensor. With high efficiency microprocessor-based analysis, it can be triggered under different carbon monoxide concentrations.

- High luminous dual LEDs to indicate different status.

- Green LED to confirm the unit is under normal operation.

- Each visible and audible warning has 4 modes to easily identify current status.

- Test button for alarm simulation.

- Dual power input: 12VDC and 24VDC operation in the same unit. No adjustment is required.

- Optional 110VAC or 220VAC adaptor is available.
