Fluke Hygrometer, ±2.5%RH Humidity Accuracy, 0.1°C Temperature Resolution - 2418208
This hygrometer measures Air temperature and relative humidity for industrial and maintenance environments. It provides simultaneous readout of both parameters on a backlit dual display and stores recorded values for later review. The instrument is compact, lightweight and designed for routine checks of indoor Air quality and HVAC system performance.
Features & Benefits
• Humidity accuracy ±2.5%RH for confident process control
• Temperature resolution 0.1°C to detect small thermal shifts
• Dew point and wet-bulb computation for moisture analysis
• 99-point memory to log and recall measurement sequences
• Response time ∼60s for 90% humidity change with 1m/s airflow
• AAA battery operation offering 200h runtime for field work
• Temperature resolution 0.1°C to detect small thermal shifts
• Dew point and wet-bulb computation for moisture analysis
• 99-point memory to log and recall measurement sequences
• Response time ∼60s for 90% humidity change with 1m/s airflow
• AAA battery operation offering 200h runtime for field work
**Applications**
• Suitable for HVAC diagnostics and balancing tasks
• Ideal for commissioning ventilation and climate control systems
• Used for environmental checks in electronics assembly areas
• Can be used for maintenance inspections in mechanical plant rooms

What humidity range can be measured?
The device measures relative humidity from 5% to 95%RH using an electronic capacitance polymer sensor suited to general IAQ and process checks.
How does it perform across the temperature span?
It operates between -20°C and 60°C with tighter temperature accuracy within 0°C–45°C and coarser limits toward the extremes to reflect sensor behaviour.
How is data displayed and updated?
Readings appear on a backlit dual display with updates every 500ms for temperature and a dedicated humidity update reflective of sensor response.
What power and storage considerations apply during fieldwork?
It runs from four AAA alkaline cells and retains up to 99 recorded points for post‑inspection review without mains power.
