Wireless Temperature Data Logger for Concrete Monitoring

Accurate temperature monitoring is a critical step after concrete pouring—especially in mass concrete applications where heat generated during hydration can significantly affect the curing process. The ideal curing temperature for concrete ranges between 10°C and 32°C (50°F to 90°F). In mass concrete, the core temperature can rise to 65°C–70°C (149°F–158°F) due to internal hydration heat.

If the temperature exceeds 70°C, there is a risk of thermal cracking and accelerated hydration, which can compromise long-term durability. Conversely, if the temperature falls below 0°C, freezing damage may occur before the concrete gains sufficient strength. Additionally, the temperature gradient between the core and surface should remain within 20°C to avoid internal stress and cracking caused by uneven expansion and contraction.

The Freshliance wireless BlueTag T10R-I  Bluetooth temperature data logger is one of the best-in-class solutions for monitoring concrete temperature during the curing process. The concrete wireless temperature data logger helps construction professionals track internal and surface temperature profiles in real time, ensuring structural integrity and compliance with project standards.

Why it solves real jobsite challenges:

Multi-channel monitoring

• Supports up to three temperature points (two with optional external probes).

• Track the core, mid-depth, and surface simultaneously

• Identify dangerous temperature gradients early

• Ideal for mass concrete and thick slabs

Customised external probes

• Probes are available in different lengths and ranges.

• Easy installation in rebar cages, formwork, or deep placements

• Suitable for dams, columns, bridges, and foundation blocks

Wireless data sync to app/cloud

• Within Bluetooth range, when any worker opens the mobile app to read the logger, the system automatically synchronises all data to all authorised users, enabling team-wide visibility.

• No need to dig out the device

• No need for repeated manual downloads

• QC engineers, supervisors, and consultants all see the same updated data

Easy reporting with mobile app & cloud platform

• Workers can generate reports instantly

• PDF reports can include signatures for approval or submission

• Cloud storage ensures data is secure and accessible anytime

Rechargeable & reusable

• Reduces cost for multi-stage pours

• More sustainable for long-term construction projects

• Coeus 4G Real-Time Temperature Data Logger

The Coeus 4G real-time temperature data logger is built for large-scale projects where teams need instant alerts and live temperature trends—especially during nighttime hydration peaks. It provides real-time monitoring of concrete temperature changes without the need for manual data synchronisation.

Why it fits modern construction requirements:

4G real-time transmission

• Engineers can monitor temperature remotely from the office or home

• Prevents missed hydration peaks or overheating during night curing

Instant SMS / Email / Mobile Alerts

• Immediate notification if temperature exceeds limits

• Allows fast action—adjust insulation, change curing methods, or add cooling

On-site LCD

• Workers can instantly verify concrete temperature during inspections without using any application

• Useful for quality assurance and daily reporting

Cloud-based multi-user management

• Large contractors can track multiple pours across multiple sites

• Simplifies reporting for engineers, supervisors, and consultants
