Chapter 2
Why is temperature control important in concrete curing?
When monitoring the temperature during concrete curing, it is important not only to measure the temperature but also to check the condition at necessary times, record the history, and share it with relevant parties.
Especially during winter construction, concrete temperature control is crucial for ensuring construction quality. On-site, this involves not only the measurement itself, but also tasks such as moving equipment to check temperatures, collecting data, organizing records, and preparing reports.
Specific temperature control methods and standards for concrete curing vary depending on construction conditions, structure, and construction specifications. This page focuses on the operation of equipment for recording and verifying temperature history.
Chapter 3
Common problems with temperature recording during concrete curing
data logging takes time.
In operations where data is checked and transcribed manually, the burden increases as the number of measurement points and the number of recordings increase.
It is difficult to check the history on-site.
In operations where data is collected and then reviewed, it can be difficult to make on-the-spot decisions at the site.
Preparing reports is time-consuming.
In some cases, it may be necessary to organize the collected data separately and compile it into a report.
Setting up and retrieving the logger becomes complicated.
For equipment used in the field, it's also important that operation, from the start of measurement to data retrieval, is easy to understand.

Points where the MR532N is useful for recording temperature during concrete curing
1. Easy to check the recorded temperature history on the spot.
Temperature data recorded with the MR532N can be transfer to a smartphone via NFC communication. features it easy to check temperature history on-site and simplifies the verification process after data retrieval.
2. Recording, transfer, and checking can be easily done primarily using a smartphone.
The dedicated app allows you to check the status, start recording, stop recording and acquire data, view a list of recorded data, configure device settings, set a passcode, and initialization the logger.
Recording can be started immediately, or scheduled, allowing you to set start and end times.
3. Easily connects to sharing and reporting tasks.
The measurement data can be display in CSV and models models You can also access the recorded data by connecting your smartphone to your PC via USB, configuration easy to use for data sharing and reporting.
