9.5.5 Solid fuel measurement
For performing solid fuel measurements complying with the 1st
BlmSchV, a testo 300 NEXT LEVEL is required with the following
equipment:
• CO sensor H2-compensated for measurements (measuring range
for 1st BImSchV measurement min. 20,000 ppm)
• Measuring range extension by fresh air dilution
• Solid fuel adapter and probe shaft with pre-filter 0600 9765
