Description
Description
The HT1000 is a handheld 0-1000 ppm carbon monoxide meter with backlight, data hold and a maximum-reading function. Compare it when a displayed CO reading and those review functions suit the measurement task. Three AAA batteries are required and are not included.
Choose the Configuration for Your Measurement
- Reading functions: CO concentration, data hold and maximum-reading display.
- Power supply: Three AAA batteries; check the supplied instructions for battery installation and use.
- Alarm behavior: Check the supplied instructions for the fixed alarm behavior. Do not assume it has the same adjustable setting controls as ST9700.

Product Details and Specifications
Handheld CO concentration readings
The HT1000 Portable Carbon Monoxide Detector gives you displayed 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
- Concentration reading — compare the stated accuracy and operating conditions with your measurement task.
- Reading procedures — check the supplied instructions for measurement and zero-check procedures.
- 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).
- Bright Backlight — Easy reading in engine bays, basements or night shifts.
- Pocket-Sized & Rugged — 160 × 55 × 40 mm ABS housing, just 156 g.
Ideal Applications
- Homes & apartments — monitor fireplaces, gas heaters & boilers
- Garages & workshops — detect CO buildup during idling or tuning
- RVs, caravans & camper vans — spot CO concentration checks
- Offices & classrooms — spot CO concentration checks
- Industrial inspections — HVAC technicians & boiler maintenance crews

FAQs
How often should I calibrate the HT1000?
Follow the supplied calibration instructions and the applicable site procedure for the required checks and calibration schedule.
Can I change the alarm level?
The listed alarm threshold is fixed at 200 ppm. An instrument alarm setting is not an exposure recommendation; follow the supplied instructions and the applicable site procedure.
Does it store readings?
The Max Hold function keeps the highest reading since power-on, useful for tracing intermittent leaks.
Compare the Relevant Alternative
ST9700 adds ambient-temperature measurement and an adjustable alarm setting to its CO display. HT1000 emphasizes hold and maximum readings. Both product pages state a 0-1000 ppm CO span, so the additional functions and alarm controls are useful points of comparison.

Questions Before Ordering
Is maximum reading the same as a downloadable log?
No downloadable recording function is established by a maximum-reading function alone. Check the model description for the specific records you need.
Can I use the alarm threshold as an exposure recommendation?
A product alarm threshold describes the instrument behavior. Configure and use monitoring equipment according to the supplied instructions and the applicable site procedure.
