CHESTERLAND, OH – April 6, 2011 CAS DataLoggers, in partnership with Grant Instruments, has introduced the OQ610‐S Concrete Maturity Logger, a unit designed specifically for measuring concrete maturity in large concrete construction projects. The Grant OQ610‐S Concrete Maturity Logger is a compact, rugged unit suitable for all concrete applications requiring accuracy and precision in determining concrete maturity. The logger is supplied in a durable, bright yellow, water proof casing making it ideal for site work in all conditionsand climates.

The OQ610‐S Concrete Maturity Logger has 6 temperature channels which are all digitallydisplayed on the unit. It can be connected directly to a PC or laptop via a USB interface for fast downloading of the readings. Using the supplied Microsoft Excel templates, the concrete maturity is calculated from elapsed time versus temperature and is quoted as a“Maturity Number”. The maturity number can be used to determine when the concrete has cured sufficiently for form work to be removed. In order to determine concrete maturity, sacrificial temperature measurement cables are‘cast’ into the concrete and severed at the surface when the concrete has cured. Grant supplies the temperature measurement cable in 100m rolls with separate plugs so that these individual sensors can be customized per job specification.The Maturity Logger is simple to use, finishing the task in the shortest possible time. This gives the confidence that the concrete is at its optimum strength, benefiting from thesubsequent efficiency, improvements and cost savings that this procedure brings.
