Four Environmental Measurements in One Instrument
The Extech 45170 combines four commonly required environmental measurement functions in one convenient meter.
Relative Humidity
The built-in precision thin-film capacitance humidity sensor provides fast-response relative humidity measurements. It is suitable for environmental checks in buildings, HVAC systems, storage areas, commercial facilities and industrial environments.
Air Temperature
The built-in thermistor measures ambient air temperature, while the Type K thermocouple input provides additional flexibility for higher-temperature applications when used with a suitable Type K thermocouple.
Air Velocity
The integrated low-friction vane wheel enables air velocity measurements for ventilation and HVAC applications. Measurements can be displayed in m/s, km/h, MPH, ft/min or knots, providing flexibility for different industry requirements.
Light Level
The built-in light sensor uses a precision photodiode and colour-correction filter. The cosine and colour-corrected light measurement function makes the instrument suitable for checking illumination levels in commercial, industrial and facility environments.
Dual LCD Display
The Extech 45170 features a large dual LCD that allows users to monitor multiple environmental parameters conveniently. Depending on the selected mode, the display can simultaneously show temperature and air velocity or relative humidity.
The display characters automatically reverse direction according to the selected Hygro-Thermo-Anemometer or Light Mode, making readings easier to view during different measurement applications.
Applications
The Extech 45170 Environmental Meter is suitable for:
- HVAC inspection and maintenance
- Air-conditioning and ventilation checks
- Air-flow measurement
- Facility management
- Building maintenance
- Commercial and industrial inspections
- Hospitality and hotel maintenance
- Indoor environmental monitoring
- Warehouse environmental checks
- Lighting and illumination checks
- General maintenance and field-service applications
