CONTEMP is an advanced concrete temperature recording and maturity monitoring system. It consists of two key components: the CONTEMP Hardware (a 3-channel temperature recorder with direct cellular connectivity) and the CONTEMP Web Application (a cloud-based platform at app.contemp.live).

1. Device Management

  • Register, search, and configure CONTEMP devices through an intuitive interface.
  • The dashboard provides a clear overview of all connected devices with detailed sensor data.
  • Customizable Sensor Settings: Rename sensors, set temperature thresholds, and define alarm limits to ensure compliance with curing requirements.

2. User Access and Permissions

CONTEMP supports multiple access levels for team collaboration:

  • Viewer — Can access temperature and maturity data and receive alerts but cannot modify settings.
  • Editor — Has full control over sensor settings, reporting, and device configurations.
  • Service & Maintenance Access — Designed for trusted service partners with predictive maintenance capabilities.
  • Silent Viewer — Access all monitoring data without receiving notifications, useful for large teams or regulatory bodies.

3. Graphing and Data Visualization

  • View and analyze historical temperature data through interactive graphs.
  • Explore data trends for different time periods to understand temperature fluctuations.
  • Paginated readouts for complete timestamped sensor records.
  • Toggle sensors on and off to focus on specific measurements for comparison.

4. Reporting Features

Generate structured reports to document temperature and maturity progress:

  • Detailed Results Report — Full export of all sensor readings in Excel format.
  • Hourly Report — Consolidates readings into hourly intervals.
  • Min/Max/Average Daily Report — Summarized daily readings.

Reports are fully customizable with adjustable time intervals, exportable in PDF or Excel format.

5. Data Consolidation

Merge temperature data from multiple CONTEMP devices into a single report. Two consolidation methods:

  1. Closest Existing Reading — Selects the nearest available temperature record from the database.
  2. Linear Interpolation — Estimates values between two readings to maintain uniform data points.

This feature is particularly useful for multi-sensor analysis, such as comparing ambient temperature with multiple concrete curing locations.

6. Concrete Maturity Monitoring

The maturity module calculates concrete strength development based on temperature history and a defined calibration curve.

Calibration Curve Definition

  • The calibration curve represents the relationship between temperature history and concrete strength.
  • Users input lab-tested strength data, either manually or by uploading an Excel file.
  • The system automatically stores and applies the calibration curve for future projects.

Maturity Calculation

CONTEMP uses the Temperature-Time Factor (Nurse-Saul) equation in accordance with ASTM C1074. The system tracks cumulative temperature exposure over time to determine concrete curing progress. Learn more about the Nurse-Saul method →

Project Tracking Dashboard

  • Current maturity level based on temperature history.
  • Target strength required for project completion.
  • Estimated time remaining until full strength is achieved.
  • Automatic notifications when concrete reaches specified strength.

Maturity Reports

  • Daily strength development progress.
  • Temperature readings from all sensors involved.
  • Applied calibration curve and corresponding calculations.
  • Available in PDF and Excel formats with images and project notes.

7. Edit & Ownership Transfer

  • Modify device and sensor settings at any time.
  • Ownership Transfer: If a device is registered to another account, a transfer request is sent to the current owner for approval.
  • QR Code-Based Registration simplifies activation, eliminating manual serial number entry.

8. Activity Logs & Security

  • Complete history of user actions: login/logout records, alarm setting changes, report generation, and data modifications.
  • Logs are permanently stored and can be downloaded as a tamper-proof PDF for compliance and auditing.
