General Product Specifications:

Filter Size: 47 or 70mm standard.

Range: Any size engine, regardless of RPM or stack diameter.

Sample Flow Accuracy:  Less than +/- 3% at dilution ratios of 15:1 or below.

System working standard flow measurement accuracy: Less than 1% of reading

QC Sample flow check meter flow accuracy (optional): <3% of reading at 20-50%FS, <2% of reading at 50-100% FS.

Sampling Time:  A nominal sampling time of 2 to 5 minutes per mode is recommended for single filter/ mode testing on a 0.1g/hp/hr 8- mode cycle-weighted emissions engine when using 70mm test filters.  The sampling time depends on the precision of the microbalance used and the brake specific emissions output of the engine being evaluated.  Up to 20 minutes per mode or more may be required for PM sampling from engines where PM after treatment is used.

Input Power:  110 or 220 VAC, 50/60 Hz (Indicate at time of order). 

Dilution Air Supply:  90 PSI, 3.5 CFM (6.2 bar, 6 m3/hr).

BG-3 Internal Sample Update Rate: 80Hz.
