315-1 CO Level Measurement CO Meter w/pressure, temperature and flame rod current.
The Testo 315-1 CO level measuring instrument. By measuring the CO level you can protect yourself from poisoning caused by flue gases escaping into the ambient air.
Safety during monitoring and adjustment of gas heating systems
By measuring the CO level, you can protect yourself from poisoning caused by flue gas 
escaping into the ambient air. 
Accurate measurement of gas pressure, ionization current and temperature with one practical instrument ensures safe conditions for you when monitoring and adjusting gas heating systems.

• Parallel measurement of safe CO level

• Monitors gas flow pressure (Fig 1)

• Monitors flue draught limit value

• Monitors flame in combustion chamber

• Fine adjustment of heating systems
  (differential temperature measurement)
