    Product Description

    Measure / monitor ambient CO levels in home and office spaces. Visual and audible alarm indicates unsafe CO levels.

    The 770 is a state of the art carbon monoxide instrument designed to measure CO in ambient air. This palm-sized unit displays readings in 1ppm increments.

    • Measure CO from O to 999ppm
    • Displays the max. CO reading in PPM since power on
    • Displays in hours and minutes, time elapsed since power on
    • Displays user set value of audible and visual alarm
    • The audible alarm can be switched on and off by pressing the SEL button

    The 770 CO Single Gas Monitor is a state-of- the-art Carbon Monoxide Instrument designed to measure Carbon Monoxide in ambient air and to perform a carbon monoxide build up test . It has a measurement range of 0 to 999 ppm (parts per million) and displays the readings in 1ppm increments.

    The unit features a personal audible and visual alarm, which is factory set at 30ppm CO but can be changed in the field to keep current with government legislation.

    Other features include: maximum reading hold, elapsed time and manual zero. The audible alarm may be switched on and off as required. Battery changing is made easy by use of a simple slide off battery compartment cover.

    The detector uses an advanced electrochemical sensor that measures Carbon Monoxide and should not be used for any other purpose.

    Note: This instrument meets the requirements of BS 7967

    Calibration is required every 12 months.

    Don’t expose yourself to Carbon Monoxide!

    Review the list below for the maximum allowable exposure limits and symptoms developed with CO inhalation.

    • 9ppm: The maximum allowable concentration for short term exposure in a living area according to ASHRAE
    • 50ppm: The Federal OSHA standard for continuous exposure in any eight hour period.
    • 200ppm*: Maximum concentration allowable any time according to OSHA. Slight headaches, fatigue, dizziness, nausea after 2-3 hours.
    • 400ppm*: Frontal headaches within 1-2 hours, life threatening after 3 hours. Maximum allowable limit in flue gas according to EPA and AGA.
    • 800ppm*: Headache, dizziness, nausea, and convulsions with 45 minutes. Unconsciousness within 2 hours. Death within 2-3 minutes.
    • 1600ppm*: Headache, dizziness, and nausea within 20 minutes. Death within 1 hour.
