Where to Buy TPI Products

The TPI 707 combustion analyzer uses a state of the art electrochemical sensor. This sensor technology provides the longest lasting, most accurate and reliable means for performing tests. The sensor in your analyzer will need to be replaced periodically and calibration is recommended once every year. The 707 will remind you when calibration is due by flashing “CAL DUE Err” for three seconds at start up if the date of calibration is one year or older.

The following guidelines will help prevent damage to your sensor:

  • Always use the mini pump filter when performing tests.
  • Always periodically check and replace the mini pump filter as needed.
  • Always make sure the in-line filter / water trap is installed properly.
  • Always periodically check and replace the in-line filter as needed.
  • Always remove water or condensation from the inside of the in-line filter / water trap assembly prior to performing tests.
  • Always use the optional oil filter (p/n A772) when performing tests on oil burning equipment.
  • Never over saturate your sensors by performing tests on equipment with gas levels beyond the capability of you analyzer.
  • Always keep the A794 water trap / filter assembly clean and replace the filter as necessary. Replacement filter part number is A762F.

707 Data Sheet

707 Manual

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.

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 instrument will 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.
