The Concrete Maturity Meter, 4-Channel has internal memory for over 10 months of continuous half-hour readings. Datum temperature and activation energy are user programmable making this meter one of the best in concrete cure time equipment.
Maturity sensors are a must have for engineers, project managers and field personnel to monitor concrete temperature and strength in real-time.
What is Concrete Maturity
Concrete maturity is a measure of the degree of hydration of concrete which is a critical factor in determining its strength and durability. The maturity method is a widely accepted technique used to estimate the strength of in-place concrete based on its temperature and time history. By monitoring the temperature of the concrete, maturity meters can calculate the maturity index which is a measure of the concrete’s strength development. This information is critical for construction professionals to make informed decisions on form removal, post-tensioning and other critical operations.
Concrete Temperature in Maturity
Concrete temperature is a key factor in maturity. The temperature history of the concrete affects the rate of hydration which in turn affects the strength development of the concrete. Maturity meters measure the temperature of the concrete and use this data to calculate the maturity index. The temperature data is used to estimate the compressive strength of the concrete which is critical for the structural integrity of the concrete structure. By monitoring the temperature of the concrete, construction professionals can ensure the concrete is curing at the right rate which is critical for achieving the desired strength and durability.
Monitor up to 4 Locations with Concrete Maturity Meter for Temperature Monitoring
One to four locations can be monitored at once with this Concrete Maturity Meter. All channels are accessed via membrane keyboard and alphanumeric display. The meter gives you real-time data on concrete strength during the curing process. You can check concrete maturity progress directly from the meter at any time.

Accurate measurements are critical for formwork removal timing as it ensures in-situ concrete has reached the required strength for further construction operations.
Calibrate Your Concrete Mix for Maturity
Calibrating your concrete mix for maturity is a key step in getting accurate results from maturity testing. The calibration process is correlating the maturity index with the compressive strength of the concrete, by testing concrete cylinders. This correlation provides a baseline for future placements and informs the decision for form removal and post-tensioning. Calibration is done on the first batch of approved concrete mix and the results are used to create a maturity curve for the mix. This curve is then used to estimate compressive strength of the concrete in real-time using data from maturity meters.
Concrete Maturity Meters in Construction
Concrete maturity meters have many applications in the construction industry. They are used to monitor the concrete curing process in real-time, providing critical information on concrete strength development. This information is used to decide on form removal, post-tensioning and other critical operations. Maturity meters are also used to ensure concrete quality and durability by monitoring temperature and maturity of the concrete in real-time. They are used in building, bridges, roads and other infrastructure projects where concrete strength and durability is critical. By using maturity meters, construction professionals can reduce concrete defects, improve overall concrete construction and optimize construction schedule.
