Technical specifications
Measurement
Effective path length 100, 200, and 400 mm (3.94", 7.87", and 15.75")
(EPL) When configuring the GPro 500 with the M400, the double value of the effective
path length must be keyed in (2⫻ effective path length).
Detection limit 0.01% Vol (100 ppm-v) with 1 m path length and ambient standard conditions
(no dust load, dry gas, O

Electrical inputs & outputs
Communication interface RS485 (to transmitter) or direct current outputs (optional)
Service interface Ethernet (to PC) as direct service interface for FW updates (not using the M400
transmitter), for off-line diagnostics and configuration database up/download
Memory slot interface SD card reader/writer for data retrieval (measurement & diagnostics), FW update
and remote diagnostics (configuration file up/download) (to be accessed using
Ethernet port). Space for data storage: 4 GB.
