REED LM-8000 6-in-1 Multi-Function Environmental Meter


This compact 6-in-1 environmental meter measures air velocity, air temperature, ambient temperature, relative humidity, light and contact temperature. The LM-8000 features Data Hold, Minimum/Max functions and has been designed for one handed operation.


  • Measures air velocity/temperature, ambient temperature, relative humidity, contact temperature and light
  • Easy to operate, designed for one hand operation
  • Air velocity is measured in m/s, ft/min, km/h, mph or knots
  • Light levels are measured in foot-candles or lux
  • Temperature is measured in °C or °F
  • Data Hold and Max/Min functions
  • Zero adjustment button (light meter)
  • Low battery indicator and auto shut off
