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).
