Introduction
This professional-grade formaldehyde detector provides instant visual alerts when dangerous HCHO levels are detected, helping prevent respiratory issues and long-term health risks.
Immediate Hazard Detection
Unlike complex measurement devices, this sensor delivers simple high/low alerts when formaldehyde exceeds the factory-set 0.075mg/m³ safety threshold - the critical level where health effects begin.
Versatile Power Options
Operates across 5-24V DC, making it compatible with most industrial and home automation systems without requiring additional voltage regulation.
Clear Visual Alerts
Integrated status light instantly indicates dangerous formaldehyde levels - glowing when thresholds are exceeded for immediate hazard recognition.
Reliable Performance
Maintains ＜2% signal stability monthly with 3-year lifespan in normal conditions. Fast (＜15s) response time catches sudden concentration spikes.
Industrial-Grade Construction
Flame-retardant PVC housing withstands demanding environments (-10°C to 50°C) while compact 47.4mm³ design fits discreetly in any space.
Note: The threshold of this sensor is factory-fixed and cannot be modified by the user. Custom threshold parameters can be set for bulk orders.
If you need to measure formaldehyde concentration accurately, we recommend the MEMS Formaldehyde HCHO Gas Detection Sensor.
