SERVOTOUGH Laser

The high performance SERVOTOUGH Laser is a range of high performance in-situ cross stack and extractive monitors designed for a variety of process control, combustion control and emissions monitoring applications in a diverse range of industries.

• Continuous in-situ or extractive monitoring
• Low detection limits
• Response time typically 2 seconds
• No direct cross interference with other gases
• Utilising the proven tuneable diode laser (TDL) measurement technique
• Suitable for high dust applications
• Low cost of ownership

Technology Used

The following instrument configurations are available in the Laser product line:
- The LaserSP monitors are mainly used for in-situ measurements across pipes, stacks, ducts with path lengths of 0.5 to 20m.
- The LaserCompact monitors are optimised for short distance measurement across pipes and extractive measurement cells with a path length of the range 0.1 to1m with low purge gas consumption option.
- The extractive LaserExact monitor multipass cell provides ppb or low ppm detection limits.

Features

• The range includes models for measuring O₂, HCl, HF, NH₃, CO, CO₂, H₂O, H₂S, HCN, CH₄ and other hydrocarbons, as well as for measuring two different gases or a gas and temperature simultaneously using a single laser.
• Robust instruments suitable for harsh and hazardous environment

Typical Applications

• Emission control systems for scrubber and abatement plants.
• Combustion control systems for boilers and waste incinerators.
• Ammonia slippage control in deNOx plants.
• Safety systems in chemical plants.
• Trace measurements in pure gases.
• Moisture measurement in natural gas.
