Alpha Moisture Systems Vietnam_ANS Vietnam

Mission Statement

To be at the forefront of hygrometer supply, design and innovation through continuous Research & Development, thus maintaining our competitive edge through lower costs and consistent high quality.

Alpha Moisture Systems manufacture a wide range of dewpoint meters and hygrometers for the measurement of trace moisture in gases and dry compressed air, encompassing an overall range from +20ºC to -110ºC dewpoint, ie 23,000 parts per million down to nearly 1 part per billion.

The extensive range of user friendly, microprocessor controlled dewpoint meters, hygrometers and sampling systems have been designed to meet the most demanding requirements and needs expressed by the industry.

Our in-house capability to design and prototype enables us to manufacture bespoke equipment to customers requirements and specifications.

The products are built using quality components, to the highest standards and specifications, compliant with our quality system which is accredited to ISO 9001:2008. We can therefore offer all our products with a generous warranty, guaranteeing reliability and performance.

 

Alpha Moisture Systems' range of portable hygrometers and dewpoint analysers have been designed with the requirements of the industrial user in mind. All instruments are fully self-contained and combine robust construction with microprocessor based electronics, to ensure that they consistently provide the operator with accurate and repeatable results. The user friendly range of instruments all incorporate the unique Desiccant Dry-Down Chamber assembly (see below), which enables the operator to obtain instantaneous readings in either the field or laboratory. Designed to operate using universally available standard batteries, the analysers can be continuously used in excess of 250 hours. Combining robust construction of high quality, fully interchangeable sensor technology and full after sales support, the portable analysers are guaranteed to provide a long and reliable service. All portable analysers are supplied ready for use with batteries installed, calibration certificate traceable to National and International Humidity Standards, two metres of sampling hose and detailed instruction manual. Contact us for further information.

The key to the operation of Alpha Moisture Systems' Portable Analysers is the unique Desiccant Dry-Down Chamber. By keeping the sensor dry between tests, the special assembly of the head ensures that the instrument is always ready for immediate use. The head assembly consists of two chambers which have a telescopic action. When the head assembly is in the 'closed' or 'Dry-Down' position, the sensor is completely surrounded by desiccant, which absorbs the remaining water moisture from the sensor and hence it is dry and ready for use. The small space at the bottom of the test chamber enables the sample pipe to be purged before the test commences without wetting the sensor. By placing a finger over the outlet of the head, the sample pressure is able to open the test chamber automatically, exposing the sensor to the gas being tested and enabling accurate reading of moisture content in the sample gas. After each test the head assembly is closed by depressing the inner section so that the sensor will again be dried by the desiccant, leaving the sensor ready for use time and time again. The desiccant is kept in the inner chamber and is not exposed to ambient room air or the sample gas, therefore there is no need for frequent regeneration or replacement of the desiccant.

Alpha Moisture Systems' range of single channel moisture analysers have been developed to meet the requirements of all applications, requiring on-line analysis at a single sample point. These instruments combine robust construction and advanced electronics to ensure that they will provide accurate moisture analysis through a long and reliable service life.

Unless stated otherwise, all on-line analysers are used in conjunction with any of our range of dedicated Ultra High Capacitance moisture sensors covering an overall range from -110ºC to +20ºC dewpoint, 0.001 to 23,000 ppm(v). Pleasecontact us for further information.

With a broad range of applications for moisture analysis, from laboratory based R&D work to OEM equipment, no manufacturer can claim to meet all applications with a single instrument.

Our range of on-line analysers combine various cabinet types from compact panel mount to robust weatherproof or bench mounting cabinets, with power supply, electrical output and indication options. All in all, the customer can be assured that whatever the application, we will have a moisture analyser which will not be beaten for long term reliability and accuracy, tailored to meet exact requirements.

Product	Power	Display	Output Units	Alarms	Analogue Outputs
Model DS1200	22-253V AC Or DC	Digital	ºC or ºF	2	4-20mA or RS485
Model DS2000	100-260V AC Or 24V DC	Digital	ºC, ºF, ppm(v)	2	4-20mA or RS485

With larger analyser installations where multiple sample points are required, it is normally advantageous to use a multi channel analyser.

The multi channel instruments are based around a sub-rack assembly into which the individual channels can be inserted. Up to a maximum of 5 channels for the Model 400 and either 4, 8 or 12 channels in the case of the G2M. These units provide economic benefits and allow easy installation for an expanding plant which may have further requirements for moisture measurement in the future.

All on-line analysers are used in conjunction with any of a range of dedicated Ultra High Capacitance moisture sensors covering an overall range from -110ºC to +20ºC Dewpoint, 0.001 to 23,000 ppm(v). Any combination of sensors can be used on individual channels in the same multi channel instrument. Please contact us for further information.

Sampling Systems are engineered solutions for extracting and analysing a representative sample of the process air or gas, which is then either vented off to atmosphere or returned back to the process.

Alpha Moisture Systems' range of sampling systems have been developed through many years of experience in industrial moisture analysis. All systems are built using the highest quality components to ensure long term performance and reliability even in the toughest of applications.

Our standard range of Sampling Systems shown here are designed to cater for most applications, however if your particular requirements are not met by any of those shown, our design engineers would only be too happy to advise and custom design for your specific application. Contact us for further information.
