LASERGAS 12944-E Main Electronic Circuit Board / Processor Set

The part number 12944-E (often found in conjunction with 12945 or 13282) refers to a specific Circuit Board Set used in the LaserGas series of gas analyzers manufactured by NEO Monitors AS.

These analyzers utilize Tunable Diode Laser Absorption Spectroscopy (TDLAS) for high-precision gas monitoring in industrial environments.

Component Identification

Manufacturer: NEO Monitors AS (Norway)

Part Type: Main Electronic Circuit Board / Processor Set

Model Compatibility: Typically used in the LaserGas II or LaserGas III series (specifically SP, MP, or Open Path models).

Function: This board serves as the “brain” of the analyzer, handling signal processing for the laser transmitter/receiver units, managing the measurement algorithms, and controlling the 4–20 mA or Ethernet (Modbus) outputs.

About the LaserGas System

If you are troubleshooting a unit containing this board, it is likely part of one of these systems:

12944-E

LaserGas II SP (Single Path): Used for in-situ monitoring across stacks or pipes.

LaserGas II MP (Multi Pass): Used for extractive trace gas analysis (ppb levels).

Common Gases Measured: $O_2$, $CO$, $NH_3$, $HCl$, $HF$, $H_2S$, and $CH_4$.

Technical Support & Replacement

Legacy Status: Many components with these specific five-digit part numbers belong to legacy LaserGas II systems.

While some are still supported, many are now being replaced by the LaserGas III or iQ2 series.

Calibration: If you replace this board, the unit will likely require a re-calibration or the transfer of configuration files from the old board to ensure measurement accuracy, as the laser’s specific “fingerprint” is often stored in the firmware.

Note: Because these boards are part of safety-critical monitoring systems (often used for explosion prevention or emission compliance), it is recommended to verify the firmware version matches your specific gas type and laser wavelength before installation.
