General Tools DLAF930SD Multifunction Environmental Meter with Simple SD Card logger - no software required
The DLAF930SD is a general-purpose handheld instrument that can make five kinds of measurements:
- Air (wind) speed and temperature (simultaneously)
- Air temperature and humidity (simultaneously)
- Light level
- Surface temperature, as measured by an optional Type K or Type J thermocouple
- Sound level (using an optional sound level probe and plug adapter)
The meter comes with a multi-function probe that is used to make the first three types of measurement. Measurements of surface temperature and sound level are made using optional accessories. Air speeds can be displayed in m/s (meters/second), fpm (feet per minute), km/h (kilometers/hr), knots (nautical miles per hour), or mph (miles per hour). Light levels can be displayed in lux or ft-cd (foot-candles). Temperatures can be displayed in ºF (Fahrenheit) or ºC (Celsius) units.
