The OQ610-S has 6 temperature channels and digitally displays the  value of all channels. 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 concrete has  cured sufficiently for formwork to be removed.

In order to determine concrete maturity, sacrificial temperature  measurement cables are 'cast into' the concrete and cut off at the  surface when the concrete has cured. Eurolec supplies the temperature  measurement cable in 100m rolls with separate plugs so that these individual sensors can be custom made to suit any particular job.

The maturity meter is simple to use, finishing the job in the shortest possible time. This gives the confidence that the concrete is at its optimum strength, benefitting from the subsequent efficiency, improvements and cost savings that this procedure brings.
