Heated CLD: For Regulatory Emissions Testing that
needs combined 10% CO
2
and 1% H
2
O quench to be
below 2% of reading, you must use the Heated CLD
version and the optional condensate removal package
(or similar apparatus).
Flow Control
Electronic proportional pressure
controller (EPC).
Sample Flow Rate CLD Standard: 0.6 LPM low flow options is standard
(1.5 to 2.5 range can be deployed if required)
Heated CLD
: Flow rate
1.5 to 2.5
LPM is standard.
Air Requirements Dry Air, less than 0.01 ppm NOx and Dew point ≤ -
10ºC.

Readout As ppm or mg/m3 preset at factory.
NOTE: If mg/m3 then NOx is expressed as NO unless
specifically set up at factory for NOx as NO2.
Outputs - AK Protocol (TCP/IP and Serial RS-232)
- Modbus TCP/IP
- 4 programmable, scalable analog outputs (Voltage or
Current).
