About Fluke Handheld Hygrometers, Psychrometers & WBGTs
Fluke offers a range of handheld instruments designed to measure various environmental parameters, including hygrometers, psychrometers, and Wet Bulb Globe Temperature (WBGT) meters. These devices are essential for professionals who need to monitor and assess air quality, thermal comfort, and heat stress in various settings.
Hygrometers
What They Measure: Hygrometers measure the relative humidity (RH) of the air, indicating the amount of moisture present.
How They Work: Hygrometers use electronic sensors that detect changes in electrical resistance or capacitance caused by moisture in the air. The sensor's response is then converted into a RH reading displayed to the user.
Applications: Hygrometers are widely used in HVAC (Heating, Ventilation, and Air Conditioning) systems, museums, greenhouses, and any environment where maintaining specific humidity levels is crucial.
Psychrometers
What They Measure: Pychrometers determine both temperature and relative humidity. They can also calculate dew point and wet bulb temperatures.
How They Work: While traditional psychrometers use a wet-bulb and dry-bulb thermometer to measure humidity based on evaporative cooling, modern digital psychrometers, like the 971, often employ electronic sensors to directly measure both ambient temperature and relative humidity.
Applications: Psychrometers are essential in meteorology, HVAC maintenance, and industrial processes where both temperature and humidity levels need to be monitored.
Wet Bulb Globe Temperature (WBGT) Meters
What They Measure: WBGT meters are designed to assess heat stress risk. They measure Wet Bulb Globe Temperature (WBGT), an index that takes into account temperature, humidity, radiant heat (globe temperature), and air movement, providing a comprehensive measure of the heat stress level in an environment.
How They Work: Modern handheld WBGT meters electronically calculate the Wet Bulb Globe Temperature (WBGT) index. This calculation is performed using readings from several integrated electronic sensors. To measure the air temperature component (representing the dry bulb temperature in traditional WBGT), the meters use an electronic temperature sensor. For the humidity component (used to derive the wet bulb temperature), they employ an electronic humidity sensor to measure relative humidity. Finally, to capture the radiant heat component, a temperature sensor is housed inside a black globe sensor. The meter's internal processor then takes the readings from these sensors and combines them using the established WBGT formula to produce the final heat stress index value, which is displayed to the user.
Applications: WBGT meters are crucial in occupational health to ensure safe working conditions in hot environments, such as construction sites, manufacturing plants, and athletic training facilities.
