The Testo 300m/xl

Setting the standard in portable compact 
combustion gas analysis instrumentation.

The Testo 300 offers more value than
ever before for the
° Boiler technicians
° Chimney sweeps
° Maintenance technicians

Service: The savings continue after the instrument is purchased.
Standard maintenance can be performed by the user.
Smart replacement parts only need to be plugged in and - they are ready to go.

This means:
- less downtime
- lower cost
- greater flexibility to replace or upgrade in the field at any time.
Applications:
Tuning of Boilers, Burners and Heaters
Engine tuning
Emission tests of CO and NO 
Differential Temperature measurements
Ambient CO detection
 
Advantages of Testo 300 M:
User friendly operation via large display and rubber keyboard with exact action point
Freely assignable function buttons gives you total control on the instrument functions
Differential pressure measurement makes filter evaluation and maintenance easy
Internal memory for 20 complete measurements
Data transfer to PC (RS 232) with Testo software
Wireless printout on a standard infrared printer for easy on-site documentation
Fast measured values for evaluating and adjusting timed and modulating burners with a short combustion improves accuracy
Available with NO(x) measurement or can be upgraded at any time
Save time and money by changing the measuring cells and rechargeable battery yourself with no tools required
Battery operation with approx. 5 hours operating time for a full days sampling
Quick battery recharging
 
Additional advantages of Testo 300 XL:
Cableless printout on attachable Comfort printer
More memory space for the values measured in up to 100 systems
Option: Memory space up to 400 systems
Measurement of CO in ambient air via CO probe
Checks for leaks in gas pipes using the gas leak detection probe
CO switch-off function if concentrations are too high
Differential temperature measurement to adjust condensing burners and to measure flow and return temperatures
Measured value can be quickly allocated to the measuring location using the barcode pen for accurate documentation and control
