Simplified Calibration

Easy to install and configure, the MR loggers are calibrated with an the abbreviated process that provides reliable accuracy in operating environments between -55 to +50 °C (-67 to 122 °F). The MR loggers include calibrations traceable to SI units through national metrology institutes to ensure cGMP, ISO 9000, and HACCP quality standards.6) Optional services are available, including extended warranties and onsite calibration.

Easy Configuration

Connectivity options include USB, wireless, and Power over Ethernet with the vNet PoE network interface. When MR loggers are used with the vNet PoE the device, installation takes minutes. With the vNet device, loggers are automatically identified on your network by the software.

Lean Validation

For applications that require validation, we offer efficient and practical protocols that allow for quick verification of data logger functions.

Software Options

Whether you need multistage alarming sent via text, email, PC display, or dial-out, or to perform a comprehensive mapping study, Vaisala has user-friendly software designed for use in regulated environments, including:

  • viewLinc Continuous Monitoring and Alarming
  • vLogSP for Validation/Mapping applications

Data Logger Options
