AIR SAMPLING APPARATUS
AIR SAMPLING PUMP MODEL BD • CODE 1949
The Model BD Air Sampling Pump is designed especially for use with the
LaMotte Air Pollution Test Equipment. Among the many features of the
air sampling pump are an adjustable flowmeter, intake and exhaust
connections, impinger holder, on-off switch, four “C” cell batteries and
AC jack. For proper maintenance and to guarantee the life and
usefulness of the air sampling pump, the following operating procedures
are recommended.
INSTRUCTIONS
1.
Check battery capacity by turning switch to the “ON” position. If the
red LED on the front of the meter fails to come on, the batteries are
too weak to operate the pump. Adjust flowrate to sample at 2.0
Lpm. If indicator float of flowmeter vibrates up and down with a
deflection of more than 0.2 Lpm, or if air sampling pump cannot be
adjusted to sample at 2.0 Lpm, replace batteries (see Battery
Replacement). Alternatively the pump may be operated with an AC
adapter (1744).
