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 1000/1400 temperature data loggers include the VL series for regulated environments and the SP series for non FDA/GxP regulated industries. The VL series of data loggers, together with vLog VL software, provide a superior, high accuracy solution for use in FDA/GxP regulated environments by ensuring tamperproof files and electronic records that meet 21 CFR Part 11 requirements. The 1000/1400 temperature data loggers include calibrations traceable to SI units through national metrology institutes.3) The SP‑series provides a compact, easily deployable, highly accurate measurement and recording device. Coupled with vLog SP software for downloading, displaying, analyzing and reporting of recorded environmental data, the SP‑series was designed for use in non FDA/GxP regulated environments. Optional browser‑based viewLinc software provides 24/7 multi‑stage alarm notification and remote monitoring for both the VL and SP series of data loggers.

Applications

The 1000/1400 temperature data loggers are ideal for monitoring and validation of:

  • Refrigerators and freezers (to -90 °C)
  • Incubators
  • Stability Chambers
  • Warehouses
  • Ambient conditions

Autonomous Power and Recording Capacity

Each data logger contains a 10-year battery and onboard memory for recording at the point of measurement. With autonomous power and recording capacity, data is immune to network and power interruptions. 3)

3) 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

  • Long-life battery and large onboard memory
  • Flexible connectivity and interoperability
  • Stable, accurate measurements
