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.

Vaisala DL2000 Temperature and Humidity Data Loggers offer precise measurements for temperature, relative humidity, and an analog sensor of your choosing. These loggers feature internal temperature and RH sensors, along with optional external channels for current or voltage inputs. These can record various parameters like differential pressure, CO2 levels, particle counts, or conductivity. Additionally, Vaisala DL2000 logger can include a Boolean channel for door switches or alarm contacts. All calibrations in Vaisala DL2000 logger are traceable to SI units through national metrology institutes.

1) The measurement results are traceable to the international system of units (SI) through national metrology institutes (NIST USA, MIKES Finland, or equivalent) or ISO/IEC 17025 accredited calibration laboratories.

Vaisala DL2000 data logger is perfect for standalone or networked setups. You can connect it directly to a PC using USB or integrate it into an existing network via Ethernet, Power over Ethernet, or WiFi. Each logger comes with a 10-year battery and onboard memory, ensuring continuous recording at the measurement spot. With its self-sufficient power and storage capability, data remains unaffected by network or power disruptions.

Vaisala DL2000 data loggers can be used with Vaisala software, either viewLinc or vLog, to download, display, and analyze environmental data. The viewLinc offers 24/7 multi-stage alarm alerts, remote real-time monitoring, and continuous data recording. The vLog is a simple solution for validation and mapping tasks. The measurement results are traceable to international standards through accredited calibration labs. Reports are customizable and exportable to spreadsheets and PDFs to meet regulatory requirements.
