The Fluke Calibration 1620A DewK Thermo-Hygrometer revolutionizes environmental monitoring for calibration laboratories. Two sensor types are available: high-accuracy ("H") reads temperature ±0.125°C (16–24°C) and RH ±1.5% (20–70% RH); standard-accuracy ("S") reads temperature ±0.25°C (15–35°C) and RH ±2% (20–70% RH). All sensors come with NVLAP accredited calibration certificates, NIST traceable, with uncertainties better than 3:1.

The DewK accepts two interchangeable sensors, stores up to 400,000 data points, and is network enabled with optional wireless capability. Up to sixteen different display setups allow monitoring multiple parameters. Advanced functions include logging, alarms, and data export. Ideal for environmental monitoring in laboratories, clean rooms, and critical facilities.
