D12-IR N2O fixed detector (nitrous oxide)

Starting at $2,548.18

Based on the infrared absorption principle, the D12-IR fixed N2O detector offers many significant advantages for the detection of nitrous oxide in the chemical, pharmaceutical industry and the medical sector. It uses a compact IR sensor in a corrosion-resistant cast aluminium housing with sintered flame arrestors to meet hazardous area classification requirements. It is suitable for most industrial environments.

The N2O D12-IR detector's graphic LCD allows you to read gas concentrations, alarm indications, and complete device configuration. The non-intrusive interface keys are operated by a simple magnet, allowing a complete device configuration and calibration without having to open the housing, a real advantage in ATEX zones.

N2O fixed gas detector assets

The D12-IR fixed N2O detector is a linear gas transmitter 4-20 mA output with measured values recorder. Many options are available to complete this device depending on the needs and applications: a 3-relay module (potentially free), digital communication board (HART or MODBUS protocol) for universal commands, or measurement logs download.

The infrared gas detector D12-IR is also available for the detection of carbon dioxide (CO2), methane (CH4), propane (C3H8), as well as many hydrocarbons. It is immune to poisons affecting catalytic sensors, insensitive to gas saturation, and can operate in an inert atmosphere. The CO2 and N2O  versions are available in two measurement ranges to best fit the needs of the applications.
