NEO Monitors - Model LaserGas™ III Portable - On-Site HF Measurement Analyser
The new portable analyser is compact, lightweight, and battery powered for on-site HF measurement. With an on-board pump and connections for Teflon tubing, the target gas is continuously transferred into the internal measurement cell. Due to the digital low power design, the analyser is operational for an entire shift with one battery charge.
The analyser provides reliable operation with instantaneous response and sufficient dynamic range to measure sub ppm and several hundred ppm HF concentrations. In contrast to many other measurement techniques, short-term HF peaks are uncovered with the LaserGas III.
Other gases such as NH3, HCl, and H2S will be implemented consecutively and are available on request.
- Gen. 3 compact LaserGas electronics
- Portable close to 2 kg weight
- Low power < 10 Watt
- Sub ppm HF detection in seconds
- No interference from other gases
- Stable calibration, no zero drift
- Other gases on request
NEO Monitors new portable analyser is compact, lightweight, and battery powered for HF measurement on the spot (other gases such as HCl, NH3, H2S on request). With on-board pump and connections for Teflon tubing the target gas is continuously transferred into the internal measurement cell. Due to the instrument´s digital low power design it may be operated for an entire working shift with one battery charge.
The LaserGas III Portable HF Analyser allows for fast and reliable operation with sufficient dynamic range to measure sub ppm and several hundreds ppm HF concentrations. The laser scans the absorption line in milliseconds. The results are averaged and subsequently output every second. In contrast to many other measurement techniques short-term HF peaks are uncovered with the LaserGas III. The LaserGas III is our most reliable and repeatable gas sensor with all electronics designed according to IEC 61508, SIL 2 (safety integrity level).
NEO Monitors LaserGas is using Tuneable Diode Laser Spectroscopy (TDLS) i.e. a non-contact optical measurement method employing solid-state laser sources. Therefore, the sensor remains unaffected by contaminants and corrosives and does not require regular maintenance. The highly selective laser source scans a single gas absorption line specific to the target gas, thus eliminating cross interference from other gases.
The LaserGas III Portable HF Analyser is the solution for reliable detection of shortterm HF concentrations, wherever diffuse emissions occur representing a risk to the work force. Focused applications are:
- Aluminium smelters: Worker protection during active pot work
- Aluminium smelters: Mapping plant emissions
- Refinery alkylation plants: Worker safety
- HF stack gas testing
