Dpstar is a leading supplier of environmental measurement sensors for temperature, relative humidity, pressure, dew point, CO2, and other environmental condition monitoring for industrial process application and research. Since the ’90s, we earned a reputation as a trusted partner to our clients through our commitment and dedication. We are an authorized distributor and supplier of measuring sensors solutions from renowned manufacturers Vaisala. Vaisala is a global leader in environmental and industrial measurement. Building on 80 years of experience, Vaisala provides observations for a better world. Vaisala is a reliable partner for customers around the world, offering a comprehensive range of innovative observation and measurement products and services.

The Vaisala RFL series CO2 Data Logger uses Vaisala’s LoRa® based VaiNet wireless technology to monitor CO2 levels in incubators and chambers. Each RFL100 data logger can communicate over 100 meters indoors, making network access simpler and saving time and costs. These data loggers securely communicate with viewLinc, Vaisala’s software for continuous monitoring, providing alarming, real-time trend data, and compliance reports for GxP regulations. The wireless RFL100 data loggers connect to viewLinc through Vaisala AP10 Network Access points. They combine reliable wireless connectivity with Vaisala’s high-performance GMP251 carbon dioxide probes. Setup is easy, with options for CO2 percentage only, CO2 percentage with temperature, or CO2 percentage with temperature and relative humidity.


Key Benefits

Secure, Long-range Wireless

Vaisala RFL100 data loggers are wirelessly networked using VaiNet access points: AP10 that supports up to 32 data loggers, saving on installation costs. Data are encrypted to ensure against eavesdropping, data tampering, and transfer errors. Vaisala RFL100 data loggers connect to viewLinc easily without local configuration and all communications are encrypted then verified by the system before being stored to viewLinc’s secure database, ensuring data integrity and security.

Powerful Signal, No amplifiers
VaiNet deployment is fast, eliminating the need for expensive Ethernet connectivity for each data logger. With a simple network topology; no repeaters, signal boosters, or mesh networking devices are required. Vaisala RFL100 data loggers communicate over 100 m (328 ft.) indoors without the aid of signal amplifiers. VaiNet uses a low-frequency signal that provides high penetration through common obstacles.

Three Measurement Options, Easy Probe Mounting
Ideal for incubators, measurement options include CO2% only, CO2% with temperature, or CO2% with temperature and humidity. To ensure secure probe positioning inside incubators, probe-mounting accessories are available. Choose optional heat-resistant probe cables to simplify heat sterilization processes.
