Mechatest Liquid Sample Station for Hydrocarbon Sampling
Mechatest Typical Sample Station

Leading in Fluid Sampling & Analysis

Mechatest Sampling Solutions has become a leading manufacturer & Worldwide supplier of Liquid & Gas samplers for the petrochemical on & offshore industry, for the power industry we are specialized in Steam & Water Analysis Systems (SWAS) used in steam water cycle.

We are a sampling system factory, we design and fabricate open and closed loop sampling systems for hydrocarbon sampling, chemicals, steam and water sampling

Mechatest has a very long term experience in this kind of fluid sampling systems, also known as spot sampling, lab sampling or grab sampling stations.

It is all about collecting of a sample of liquid or gas direct from a pipeline, tank, stack, steam generator, (waste)water or any other application with the intent of transporting safely the sample to a laboratory for analysis.

  • Reducing costs by process optimization
  • Quality improvement of products by taking representative liquid samples
  • We guarantee to control your quality and preventing production loss

Sample stations for Power industry - Mechatest



The oil and gas industry is fragmented into three major segments upstream, midstream and downstream. 

To fulfill the demand of energy and natural resources in various nations, there would be a need to explore more oil and gas reserve globally. 

Mechatest is highly capable to give the finest solutions and services for the liquid and gas industry.

Closed loop, No waste, No pollution, NO emission









Liquid Grab Sampling Systems

Mechatest Fixed Volume Liquid Grab Sample System
Mechatest Liquid Sample System

The mechatest liquid grab sample systems can take samples of liquids under normal and high pressure or under normal atmospheric circumstances.

The glass bottle needle samplers can be used as closed loop sampler on low process or vapor pressures, non hazardous or toxic, water or viscous solutions. With the "fixed volume" type liquid sampling system you can obtain high pressure liquid samples.

Gas Grab Sampling Systems

Mechatest Liquefied Gas Grab Sample System
Mechatest Gas Sample System

The mechatest gas grab sampling systems can take samples of gasses under process conditions.

The systems with sample cylinders enable operators to obtain samples of gasses with high process pressures, liquefied gasses, hazardous or toxic gasses.

Steam Sample Panels

The standard Mechatest Steam sample panels are pre-assembled sampling solutions for the steam and water sampling, conditioning, and analysis in the power cycle according to ASME PTC 19.11. 

Mostly the steam and water sampling panels are used in combination with water analyser equipment for analysis of Conductivity, pH, dissolved Oxygen, Silica, Sodium etc.

Bottle Grab Sampler Products

Mechatest Liquid Needle Samplers, Grab sample system, ECO Sampler, Govosam
Mechatest Liquid Samplers

Mechatest new Liquid Grab Samplers with Needle Adapter for use with Schott Duran bottles and septum cap. 

This modular design is unique and has a lot of advantages:.

Typical process samplers, sampling into a bottle and directly under process conditions.

The bottles with safety septum style provide closed loop emission free, representative sampling with minimum dead volume. 

Bottle holder designed for "standard" Schott Duran or Dopak bottles with cap and septum in volumes of 2, 10, 50, 100, 250, 500 and 1000 ml.

NeSSI Sampler

Mechatest NeSSI Sampler

With great pleasure we like to introduce our new NeSSI Liquid Grab Sampler.

The NeSSI Sampler is specific designed to take liquid samples, manual or automatic, and directly onto the ANSI/ISA 76.00.02 base compliant sampling system substrate or platform.

Flow Thru Sampling Systems

Mechatest Flow Thru Sampling Systems
Mechatest Flow Thru Sampling Systems

The Mechatest flow thru grab sampling systems are compact systems for the extraction of representative samples from pipelines without process interruption.

This in-line system can be direct mounted to the process loop and will extracting representative samples from the process stream, emission free, while providing operator safety. Easy to install and operate, process pressure is used to dispense the sample into the sample bottle.
