Wireless Concrete Temperature Loggers

Sensors that go into the pour and record every 15 minutes, from the first hour to the day you strip the forms. Switch on, scan the QR code, and the first temperature appears in the Proxigen app.

Both use the same app, cloud and one-button setup. The difference is how many points you measure.

CTM01

One probe for everyday pours: slabs, columns, walls and precast elements.

CTM02

Two probes, top and bottom, to follow the temperature difference across thick pours.

The maturity method

Concrete tells you how strong it is. Through heat.

01Pour0 h Probes go in before the concrete. Tie the probe to the rebar at the point you care about, usually the core of the section. Switch the sensor on and it records a reading every 15 minutes.

02Heatfirst 1 to 2 days Hydration heats the core. Cement reacts with water and releases heat, usually peaking within the first day. With CTM02 you see the top and the bottom of the pour side by side.

03Strengthday 2 to 4 Heat × time = maturity. The maturity method turns the temperature history into an estimate of in-place strength, so you depend less on waiting for cube results.

04Readyday 4+ Strip on data, not the calendar. When the estimated strength reaches your target, plan formwork removal with the full temperature record to back the decision.

Same Setup for Both Sensors

No pairing menus, no settings to change.

Hold for 3 seconds

Press and hold the button. One long flash confirms the device is on.

Scan the QR code

Open the Proxigen app and scan the QR code on the device.

See the first reading

The app connects on its own and shows the first temperature.

No Reading Gets Lost

Both sensors record a reading every 15 minutes and keep about 6 months of data in their own memory. When the app connects, every stored reading is sent to Proxigen Cloud, so gaps between site visits never become gaps in your records.
