CO/Temp Meter (with adjustable alarm)
Measures of Carbon Monoxide and Temperature
(Model No.: TM- 801)

TM-801 CO meter is used for measuring the CO levels upto 1000ppm.

Carbon monoxide (CO) is a poisonous gas that has no smell, color or taste. But it is very dangerous and reduces the oxygen-carrying capacity of blood that causes you unwell, illness and death.

Temperature range: -20~50 ºC (-4~122 ºF).

Dual and digital display of the CO and temperature measuring

Adjustable alarm: Adjustable alarm threshold level (25 /35 /50 /100 /250 /400 /800 /Randomly adjustable); Enable/Disable alarm

Power supply: 1.5V UM-4(AAA) battery × 6 PCS or AC100~240V or DC Adaptor 9V/0.5A(9mm).

Operating Temperature & Humidity: -20°C to +50°C, <80% RH.

Storage Temperature & Humidity : -10°C to +50°C, <70% RH.

Weight: approx 250g (Batteries not included).

UM-4(AAA)1.5V battery ×6 PCS, user’s manual, carrying pouch.

Carbon monoxide content in the air | Inspiration time | Symptoms and applicable standard

9 ppm : Maximum indoor air quality level.

35 ppm | 8 hours : The average exposure level per U.S. OSHA workplace standards.

50 ppm | 8 hours : The maximum average exposure of the U.S. OSHA workplace standards.

0.01%(100 ppm) | 2~3 hours : Evacuate people from enclosed space if the CO concentration exceeds 100 ppm per OSHA exposure limit. Mild headache.

0.04%(400 ppm) | 1~2 hours : Headache occur in 2.5 hours to 3.5 hours.

0.08%(800 ppm) | 45-min : Dizziness, nausea, cramps(convulsions).

0.16%(1600 ppm) | 20-min : Headache, dizziness and will be dead within 2 hours.

0.32%(3200 ppm) | 5~10 min : Headache, dizziness, vomiting and will be dead in 30 minutes.

0.64%(6400 ppm) | 1~2 min : Headache, dizziness and will be dead within10 to 15 minutes.

1.28%(12800 ppm) | 1~3 min : Cause death.

Indoor Air Quality CO2 Monitor
(Model No. CEM DT-802)

The Carbon Dioxide (CO2) Monitor is designed for air quality control and health control by measuring Carbon Dioxide (CO2) levels in areas where it needs to be monitored, such as factories, schools, offices, transportation lines, and so on. The measured COs value in ppm (parts-per-million) will be displayed on the LCD with tee states indication: Good (0 to 800ppm), Normal (800 to 1200ppm), Poor (>1200ppm).

An acoustic alarm sounds when the CO2 level is exceeding the defined level.

Checks for Carbon Dioxide (CO2) concentrations with Max/Min value recall function.

Maintenance-free NDIR (non-dispersive infrared) CO2 sensor.

Indoor Air Quality displayed in ppm with
Good (380 to 420ppm),
Normal (<1000ppm),
Poor (>1000ppm) indication.

Accuracy: ±75ppm(0-2000ppm)/±8%(2000-9999ppm)

Accuracy: ±3%RH(25°C/30 to 99%RH ), ±4%RH(25°C/0 to 30%RH)
