Tenmars Hot Wire Anemometer
Measures air flow velocity, temperature and humidity
(Model No.: TM- 4002)

The TM-4002 hot wire anemometer is used to undertake measurements of air velocity and air temperature / humidity in spaces where the vane anemometer cannot be used, typically in HVAC ducts.and vents. This instrument benefits from a LCD triple display, which can show both air speed and temperature, and the backlight makes this display easy to read in dimly lit areas.

The TM-4002 is able to calculate both air velocity, and air volume and has a wide array of features designed to make testing simple and fast.

The TM-4002 hot wire anemometer lends itself to many applications, including air balancing, fire matrix testing, paint booths, ventilation systems, and environmental testing. The probe is housed within a telescopic device for access to, hard to reach areas.

Displays air (wind) speed in meters/second, feet/minute, kilometers/hr, knots, and miles/hr.

Displays maximum and minimum readings and holds any reading.

Manual Data Memory and read function (99 records).

Many applications include: warehouses, factories, office buildings, restaurants,
schools, library, hospitals, photographic, video, parking garages, museums,
art galleries, stadiums, building security.

Display: 60mm(W) x 47mm(L) monochrome LCD and backlight.

Internal Power: LR6 (AA) 1.5V x 6 Batteries

External Power: Power Adaptor AC/100-240V to DC 9V/0.5A

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.

Tenmars 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 up to 1000ppm.

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