INDUSTRIAL LASER GAS ANALYSIS

TDLAS Gas Analyzer Manufacturer for Industrial Process Monitoring

Q: Which gases and measuring ranges are available?

Our analyzers measure SO2, NO, NO2, N2O, O2, CO, CO2, NH3, HCl, HF, CH4 and H2O. Gas availability, measuring range and units depend on the model and configuration.

Q: How do I choose between in-situ and extractive measurement?

Choose by process temperature, pressure, dust, moisture, response time and installation space. In-situ analyzers measure directly in the process; extractive systems use a sample gas line.

Q: Can the analyzer connect to PLC, DCS or CEMS?

RS485 and 4–20 mA outputs are available across multiple models. Relay and switch outputs depend on the analyzer. See the model specifications for interface details.

Our analyzers measure SO₂, NO, NO₂, N₂O, O₂, CO, CO₂, NH₃, HCl, HF, CH₄ and H₂O. Gas availability, measuring range and units depend on the model and configuration.

How do I choose between in-situ and extractive measurement?

Choose by process temperature, pressure, dust, moisture, response time and installation space. In-situ analyzers measure directly in the process; extractive systems use a sample gas line.

What process information is required for model selection?

Target gas, expected range, background gas composition, temperature, pressure, dust, moisture, duct size or optical path, preferred installation method and hazardous-area requirements.

How are dust, temperature and pressure effects handled?

Options include purge, filtration, heated sampling and compensation, depending on the model and process conditions.

Can the analyzer connect to PLC, DCS or CEMS?

RS485 and 4–20 mA outputs are available across multiple models. Relay and switch outputs depend on the analyzer. See the model specifications for interface details.
