testo 325-I COhigh [O2]

The testo 325-I COhigh [O2] is your step to affordable flue gas analysis. Easy handling and low costs make it the ideal portable partner for

  • Checking the atmosphere of thermal processes in the production sector (funnel furnaces, hardening furnaces, smelting and annealing)
  • Adjusting process burners and gas motors.

The readings are displayed constantly on the display for as long as the pump is running.

  • Gas sensors can be easily changed by the user
  • Instrument protection on account of detachable condensate trap

testo 325-2 / 325-3

The testo 325-2 and -3 instruments offer the standard functions of flue gas analysis for the basic adjustment of oil and gas burners.

testo 325-2 measures O2 in flue gas, flue draught and calculates flue gas loss and efficiency.

testo 325-3 measures the CO level (up to 2000 ppm), draught and gas flow pressure.

  • TÜV approved O2, CO2 and temperature measurement function
  • Measures flow/return temperature with separate probes; T display (325-2/3)
  • Data documentation printed on site
  • Magnetic SoftCase for protection and positioning

 

testo 325 M / 325 XL

testo 325 M and XL instruments supply all important parameters(O2, CO, °C) at a glance.

They enable differential temperature and differential pressure measurements (40/200 hPa switchable) and fulfill all the requirements for the adjustment, maintenance and servicing of gas and clean oil burners (CO to 4000 ppm).

  • O2 TÜV approved
  • Data documentation printed on site
