Environmental data loggers for unattended long-term monitoring between field visits — tamper-evident logging of temperature, humidity, CO₂ and gas flow data for MRV compliance.
Continuous monitoring hardware allows unattended long-term data collection between field visits — essential for projects where methodology requires continuous or high-frequency measurement. Temperature, humidity, gas concentration and flow data can all be logged automatically, reducing field visit frequency and improving data continuity.
For carbon credit MRV, tamper-evident logging and audit trails are important — some VVBs require evidence that monitoring data cannot be retroactively modified. Look for loggers with sealed memory, timestamped entries and ideally cloud sync with access logs.
The most widely deployed environmental data logger in field research and carbon project monitoring. Bluetooth-enabled for easy data download via smartphone app without removing the unit. Accurate to ±0.2°C and ±2.5% RH, with up to 2.5 years of battery life on two AA cells. Weather-resistant housing. Used by thousands of environmental monitoring deployments worldwide.
The Bluetooth download means field teams can collect data without opening the logger housing — preserving seal integrity and reducing the risk of contamination or accidental data loss during data collection visits.
For projects where cellular connectivity exists but is intermittent, the RUT241 provides reliable 4G data transmission with SIM failover. Combined with a small solar panel and battery, it provides continuous power and connectivity for remote monitoring stations — allowing real-time data access without site visits. Compatible with Modbus and standard industrial sensor protocols.
Real-time remote monitoring access allows project developers and VVBs to review data without physical site visits — reducing monitoring costs and enabling faster identification of equipment issues.
A USB plug-and-play CO₂ logger accurate to ±50ppm. Useful for cookstove projects monitoring indoor air quality co-benefits, or for initial biogas concentration spot checks. Data downloads directly via USB to Excel or the free EasyLog software. Small and unobtrusive enough to leave in a household for extended monitoring.
Indoor air quality co-benefits (reduction in household CO₂ and particulate exposure) are a Gold Standard co-benefit for cookstove projects. A CO₂ logger provides quantified evidence of this co-benefit for your project documentation.
The industry standard for research-grade environmental monitoring stations. Programmable in CRBasic, supports up to 20 analogue input channels, SDI-12 and RS-232 digital sensors. Built for permanent installation in extreme environments. If your monitoring station needs to log multiple sensors simultaneously — gas concentration, flow, temperature, pressure, humidity — this is the professional answer.
For complex projects with multiple simultaneous measurements at a fixed monitoring station, a multi-channel logger eliminates the need for multiple independent loggers — reducing hardware cost, power requirements and data management complexity.
