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.

DL4000 series of data loggers are designed to interface with a wide range of transducers, transmitters, and sensors with a DC voltage or 0 – 20 mA current loop output. DL4000 is a simple solution for recording and monitoring pressure, flow, fluid level, PH, electrical properties, moisture, and gas concentrations. Ideal for use in standalone or networked applications, the DL4000 Universal Input logger connects directly to a PC with USB or installs to an existing network via Ethernet, Power over Ethernet or WiFi. Each logger contains a 10-year battery and onboard memory for recording a
wide range of variables at the point of measurement. With autonomous power and recording capacity, data is immune to network and power interruptions.

The DL4000 data loggers can be used with Vaisala software, either viewLinc or vLog, to download, display, and analyze environmental data. The viewLinc monitoring system provides 24/7 multistage alarm notification, remote, realtime monitoring and gap-free data. The vLog software is a simple solution for validation/mapping applications. The DL4000 data loggers include calibrations traceable to SI units through national metrology institutes.2) All reports are customizable and can be exported to spreadsheets and PDF to provide records that meet the requirements of 21 CFR Part 11 and Annex 11. Choose the DL4000 VL series data logger for GxP-compliant environments and the DL4000 SP series for non-GxP applications.2)

2) 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.

Key Benefits

  • Easy to set up and use
    The DL4000 data loggers can be used with Vaisala continuous monitoring system software viewLinc for monitoring and analyzing environmental data. Vaisala’s OPC Server software can also be used to integrate the DL4000 data loggers with non-Vaisala systems.
  • Onboard battery and autonomous memory
    Data is recorded at the point of measurement making it immune to network and power interruptions. With typical battery life of ten years and large onboard memory, the DL4000 is a reliable solution for logging multiple parameters with a single device. Remote alarming ensures you know when thresholds are breached.
  • Flexible connectivity options
    To access the DL4000 data, connect directly via USB, or a network via Ethernet, Wi-Fi, or use Vaisala’s vNet interface for Power over Ethernet connectivity.
