Validatable Relative Humidity & Temperature Data Loggers - Specifications


Veriteq's VL 2000 series loggers are fully validatable and designed for regulated industries/pharmaceutical applications — with NIST-traceable, ISO/IEC 17025 calibration, cGMP/FDA compliant measurement and redundant recording of temperature and humidity.

  • Portable self-contained relative humidity & temperature data logger for critical validation applications

  • Equipped with internal relative humidity & temperature sensors, memory and ten-year battery

  • Optional external channel for voltage or current inputs allow recording of differential pressure, level, particles, conductivity or C02

  • Optional Boolean channels for door switches or alarm contacts

  • Tamper-proof operation produces secure documentation for validation records

  • Password-protected setup, download and calibration functions ensure integrity of collected data

  • Records relative humidity (RH) and temperature without wires, power cords or connections

  • Traceable instrument-grade RH and temperature measurement accuracy

  • Adjustable logging intervals with multi-year data recording capacity

  • Premium quality precision sensors offer exceptional in-calibration data logger performance
