L1OEM NDIR channels — into your instrument
The sensing core with an interface contract. In-house 2-beam optics with reference channel and heated cell; calibration traceable to national primary gas standards. Delivered as OEM board or benched module, scoped to your gas, range and matrix.
L2Field instruments — install and connect
Complete transmitters and transducers with datasheet, manual and a per-unit calibration record — the number you defend in an audit.
L3Systems — collect, alarm, report
Controllers and cabinets that turn field readings into alarms, records and SCADA data — the layer that makes compliance repeatable.
What each channel measures
One matrix, from our own datasheets: the measuring principle that serves each gas group and where it is typically used.
