Analyser Systems
Analyser measurement design and implementation
Mechatest is a system integrator, we provide engineering and manufacturing of high quality and reliable analyser solutions. Analyser systems can improve product quality, increase the yields of products with higher economic value, increase product throughput and output and reduce energy costs.
Process analyzer systems should be considered for product quality control when frequent and rapid measurements are required because of fast and substantial variations in process stream quality.
Today, environmental standards are becoming more stringent. Process analyzers are used to detect hazardous plant conditions and for monitoring government-mandated requirements concerning pollutants in ambient air, stack emissions, and effluent streams.
Mechatest offer a full design and manufacturing capability for the supply of analyser solutions in cabinets and walk-in shelters.
Our solutions are suitable for outdoor use in an industrial environment and ATEX Zone 1 or 2.
After selecting the analysers and designing the sample systems it is very important to choose the environment for the complete system.
The assembly of multiple instruments in a shelter creates several economic advantages:
- Reliable / stable measurement
- A good working environment for monitoring and maintenance
- Lower maintenance costs
- Longer lifespan of the equipment, Etc.
- In a lot of cases a “walk-in” shelter is a very good and durable solution.

Analyser Cabinets and Rack Mounted
The design of the analyzer cabinet or shelter must consider many factors:
- Local ambient conditions
- Hazardous area classification
- Power distribution
- Heating, Ventilation / Air conditioning (HVAC)
- Gas detection
- Construction shelter GRP, Concrete, Stainless Steel, Coated steel
- Construction floor / base
- Calibration facility
- Grab sample point
- Carrier gas facility
Analyser Walk-In Shelters
Engineering and manufacturing of high quality analyser shelters.
Mechatest offer a full design and manufacturing capability for the supply of analyser shelters.
Our shelters are suitable for outdoor use in an industrial environment.

Steam/Water Analysis Systems (SWAS)
Mechatest is well known for
it’s excellent quality steam and water sampling and analysis solutions SWAS built as per ASME PTC 19.11 and VGB S-006.
The Steam/Water Analysis Systems (SWAS) are designed conform latest modern technology and has been continuously improved to keep the reability of your water steam analysis safe at all times and to protect your power plant from corrosion and scaling, suitable for power plant chemistry.
Steam and Water Analysis System (SWAS) are designed for continuous monitoring and control of water and steam purity in the boiler plant cycle and at other important analysis points. The SWAS sampling system shall obtain samples from steam and water pipelines which shall be adequately conditioned and flow through water analysers for continuous analysis and provide parallel facility for grab sampling.
The analyser outputs signals shall be used for continuous monitoring of various parameters like analysis of pH, Specific Conductivity, Cation Conductivity, Degassed Conductivity, Sodium, Silica, Dissolved Oxygen, Phosphate, Chlorides, TOC etc.
Importance of Sample Probes
Sample probes are very important and mostly an underestimated part of the sampling system.
Why you should use sample probes;
- Free First Filtration Effect!
- Faster Response (< Lag Time)
- Representative Sample, better results!
- Moisture Filtration (fallback) Principle
Sample Probes Types
- Open Probes
- Filter Probes
- Multiport Probes
- Heated Probes
- Fallback Probes
- Small Bore Gas Probes
- Retractable Sample Probes
- Isokinetic Steam Probes
Calculating Services;
- Lag Time
- Velocity
- Probe Vibration
- Moisture Fallback Effect
Sample Transport Lines
Flexible Sample Transport Line
- Temperatures from frost protection up to 200°C
- Up to 150 m in a row
- Regulated or self-regulating
- Chemical Resistance
- Exchangeable Lines
- Heat Tracing
- Avoid Condensation (stay above dewpoint)
- Don’t Loss Low Concentration Components !
Liquid Recovery Systems
The Mechatest liquid sample recovery systems are specifically designed to collect liquids of sample effluent from process liquid analysers and return this to the process line or any other suitable location.
Because of the high sensitivity of the process analysers the sample discharge needs to drain under atmospheric pressure conditions. Liquid sample recovery systems provides a stable condition at the process analyzer outlet.
Typical applications are analysis of gasoline, bio
The system is also ideal for use in applications where it is undesirable to discharge hydrocarbons or chemicals into sewage drains.
Effectively dealing with the effluent from process analyzers is a concern to both environmental engineers and process analyzer engineers at petrochemical plants.
