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

Quality Product ~ Made in Taiwan

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.

• 4 digital LCD with maximum 1000 counts.
• CO range: 0 ~ 1,000ppm.
• Temperature range: -20~50 ºC (-4~122 ºF).
• Sample rate: 1 time/second
• Dual and digital display of the CO and temperature measuring
• Max/Min/Average Hold.
• Data Hold.
• Low battery indication
• Auto power off with disable function.
• Adjustable alarm: Adjustable alarm threshold level (25 /35 /50 /100 /250 /400 /800 /Randomly adjustable); Enable/Disable alarm
• LED Backlight.
• Auto power OFF and disable function.
