AWS-6020 Sample System
The AWS-6020 sample system is designed for trace moisture measurement in gas and general compressed air sampling, enabling the sensor to operate under optimal sampling conditions while safeguarding the hygrometer from high pressures and contaminants, particularly in hydrocarbon environments.
Enclosed within an IP66-rated weatherproof cabinet, the AWS-6020 integrates pressure regulation, filtration, flow control, a three-port sample selection valve, sensor holder, dewpoint sensor and dewpoint meter. With this system, both the dewpoint sensor and meter are protected against environmental exposure.
Alpha Moisture Systems sample systems provide engineered solutions for extracting and analysing a representative sample of process air or gas, which is subsequently either vented to the atmosphere or returned to the process. This range has been developed through extensive experience in industrial moisture analysis. We construct all systems from high-quality components to deliver long-term performance and reliability in demanding applications. While we can supply a standard configuration, this sample system is customisable to suit your application requirements.
Whatever the challenge — Alpha Moisture Systems has you covered.

Applications
AerospacePortable dewpoint meters are crucial in the production of aeronautical parts requiring vacuum furnace heat treatment with very dry argon, and for verifying the dryness of welding shield gas at the torch head according to NADCAP standards.
HDPE ProductionUtilised for spot-checking moisture in flammable gases like ethylene feedstock, portable dewpoint meters ensure safety and efficiency in the production of polyethylene to avoid decreased yields caused by excessive moisture.
Injection MouldingPortable dewpoint meters are used to verify the dryness of air circulating through plastic pellets, improving surface finish, colour, and opacity of products — increasing yields and reducing production costs.
Medical GasesEssential for ensuring the reliability and accuracy of moisture content in hospital air systems, portable dewpoint meters help conduct continuous monitoring and quarterly spot checks to prevent microbial growth and potential infection — meeting NHS HTM02 standards.
Speciality GasesPortable dewpoint meters facilitate accurate moisture measurements in calibration gases, minimising the valuable product expended during the test process and ensuring compliance with specifications.
PharmaceuticalsPortable dewpoint meters are crucial for spot checks on inert blanketing gases in medication and medical device production, preventing microbial growth and ensuring the dryness necessary for freeze-drying processes.
Power GenerationFor routine spot checks on hydrogen used in alternator cooling, portable dewpoint meters help maintain efficiency and safety by ensuring moisture is below critical levels to avoid condensation.
Frequently Asked QuestionsIf you have a question that’s not answered below, please contact us
What is the standard configuration of the AWS-6020 Dewpoint Sample System?
The AWS-6020 Sampling Systems typically include: an intrinsically safe sensor with sensor holder/sample cell, pressure regulator (heated is optional), filter unit, flow indicator and a pressure gauge (inlet), pressure gauge (outlet) and all pipework in high-grade stainless steel. However, we can design a system specifically for your application. Please contact us to discuss your exact requirements.
I need to measure moisture in Compressed Gas but my requirements are complex. Which sample system would be suitable?
We understand that dewpoint measurement requirements for Compressed Gas applications can vary. This is why we offer a consultation and customisation service; our technical team are more than happy to discuss your sample system requirements. Please contact us to discuss your exact requirements.
Can I customise the AWS-6020 sample systeem to meet my specific industrial requirements or environmental conditions?
Yes, we design and manufacture customized sample systems for hazardous, non-hazardous areas and specific industrial and environmental requirements. Please contact us for further information.
What are the recommended maintenance procedures for the AWS-6020 Sample System?
These can vary depending on the condition within the application, we can advise upon initial discussion at design stage. Please contact us to discuss your exact requirements.
Our application will involve dewpoint sample systems installed outdoors, and in very hot conditions, how can we maintain a stable sample temperature to the dewpoint transmitter inside the enclosure?
We take into account all your considerations when designing a bespoke solution for your application. We house the dewpoint transmitter in a stainless-steel enclosure with seals. Vortex coolers are installed on the cabinet to control the inside temperature. There are various options available. Please contact us to discuss your exact requirements.
