Stop Carbon-Monoxide Poisoning Before It Starts
The HT1000 Portable Carbon Monoxide Detector gives you instant, lab-grade CO readings from 0 to 1000 ppm in just two seconds of warm-up. A bright backlit LCD shows live concentration, while an 85 dB buzzer and flashing icon warn you the moment levels exceed 200 ppm.
Main Benefits
- Accurate & Sensitive — ±10 ppm or ±15 % FS accuracy for reliable safety checks.
- Fast Response — Electrochemical sensor refreshes every second; manual ZERO button eliminates drift.
- Data Hold + Max Read — Freeze a reading or view peak ppm at a glance.
- Low-Power Design — Auto power-off after 15 min; runs >80 hours on 3 × AAA (not included).

FAQs
How often should I calibrate the HT1000?
For professional use, perform a zero check before each shift and a span check every 6 months with certified CO gas.
Can I change the alarm level?
The audible alarm is factory-set at 200 ppm per OSHA short-term exposure limits and is not user-adjustable.
Does it store readings?
The Max Hold function keeps the highest reading since power-on, useful for tracing intermittent leaks.
