Features & Benefits

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.

FAQs

Frequently Asked Questions

Why should I purchase a pump driven CO analyzer rather than a less expensive CO monitor?
A pump driven analyzer is a much more versatile tool. The pump draws a sample into the instrument which allows source pinpointing. A pump driven instrumentwill also respond faster, and can be used for hot air (flue) sampling.

Can a CO analyzer be used for heat exchanger testing?
While a CO analyzer can provide a safety test of the furnace, it cannot provide a discernable test for heat exchanger integrity. The TPI HXG2 and HETKIT are recommended for this test and together are AGA approved.

How often should I calibrate my CO analyzer?
It depends on the use of the instrument. If used for service work, it is recommended that an annual calibration be performed. If any aspect of worker safety is included in the instrument’s job, monthly calibration is recommended.

If I perform my own calibration, do I increase my liability?
As long as traceable calibration gas is used and manufacturer’s calibration procedures are followed, liability will be minimized. Calibration records should be documented and retained.

How many calibrations can I expect out of a 21 liter bottle of calibration gas?
35-50 calibrations

How long will the CO sensor last?
Two to three years.

Tech Tips

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.
  • 3200ppm*: Headache, dizziness, and nausea within 5-10 minutes. Death within 30 minutes.
  • 6400ppm*: Headache, dizziness, and nausea within 1-2 minutes. Death within 10-15 minutes.
  • 12800ppm*: Death within 1-3 minutes.

* With exposure to this concentration and higher the effects can vary depending on size, age, sex, and health.
