Moisture analyser gains ASTM approval
Moisture analyser gains approval and conformity to ASTM test method D7191-05 for determining moisture in plastics by a relative humidity sensor.
Able Instruments and Controls has announced the approval and conformity of the Computrac Vapor Pro moisture analyser to ASTM method D7191-05.
An alternative to titration methods, the D7191-05 test for determining moisture in plastics by a relative humidity sensor was adopted by ASTM after its most recent round of balloting in autumn 2005.
Relative humidity sensor technology has advantages over traditional titration methods, making it suitable for companies that do not want the recurring costs of chemicals, glassware or disposal.
The Computrac Vapor Pro is claimed to be durable enough for the production floor yet versatile enough for the laboratory.
It requires little training to use accurately so that even an inexperienced operator can produce reliable results.
"Many of our customers in the plastics industry have been looking for a reagent-free, ASTM method that would allow them to test quickly and easily for moisture in their raw materials and finished products," said Dave Quelch, Senior Product Manager for Able Instruments and Controls.
"A task group was initiated to develop a moisture-specific method based on the relative humidity detection technology to provide a safe and cost-effective alternative for testing moisture content in plastics".
