Get readings, alarms and pour reports from anywhere, so you can build with confidence and efficiency.
From concrete pours to curing tanks, steam tents, and lab environments — we have you covered.
Flagship
Concrete Temperature & Maturity
Ultra-accurate, low-cost concrete temperature and maturity logger (part no. CONTMP) with built-in cellular and WiFi. No gateways, no subscription. Maturity by the method of ASTM C1074, Nurse-Saul or Arrhenius.
Curing & Flooring
Curing Rooms & Flooring
Precision temperature and humidity monitoring for concrete curing rooms and flooring. An ideal alternative to competitor products like Humboldt's RH moisture meter kit. Water-resistant external RH probe enables direct measurement in high-moisture environments.
Curing Tanks & Labs
Curing Tanks & Lab Monitoring
Multi-channel temperature and humidity logger designed for curing tanks and lab monitoring. The temperature probes are meant to be submerged in curing tanks with lime, and can be easily replaced after the lime chews through them. Meets NSF/ANSI 456, with e-paper display and audible/visual alarms.
Every feature designed around the needs of concrete professionals.
Get notified when core and surface temperatures drift beyond limits, preventing thermal cracking in mass concrete.
Set alerts for extreme temperature conditions that could affect curing quality. Notifications by email and text message.
A PDF pour record and an Excel file of every reading for each finished pour, with calibration-based strength estimates.
Grant access to your entire team — engineers, project managers, inspectors — all at no extra cost.
Minimal sacrificial parts. Save millions on large infrastructure such as LRT, Bridge, or Hydro Electric projects.
Ambient + two external sensors for comprehensive monitoring.
Alkaline or Energizer Ultimate Lithium cells, changed on site with no tools.
Built for harsh job site conditions. Tested down to −36 °C (−33 °F).
Two-year limited warranty from the invoice date. Embedded sensors are sacrificial and stay in the pour.
Unlike competitors that charge per sensor, per month, or per project — CONTEMP has zero recurring costs.
No subscription, no data charges — 10 years of cloud access included
Built-in cellular, plus WiFi where there is no coverage
