 Professional Multifunction environment meter

    The digital multifunction environment meter has been designed to combine the functions of sound level meter, light meter, humidity meter, type K thermometer and infrared thermometer. It is an ideal multifunction environment meter instrument with scores of practical applications for professional and home use.
     
Features:
  • The sound level function can be used to measure noise in factories, schools, offices, home etc. checking acoustics of studios, auditoriums and hi-fi installations.
  • The light function is used to measure illuminance in the field. It is fully cosine corrected for the angular incidence of light. The light sensitive component used in the meter is a very stable, long life silicon ciode.
  • The humidity/temperature use a humidity/semiconductor sensor and K type thermocouple.
  • 5 in 1 for Anemo, %RH, Lux (Fc), Type K and Infrared temperature(¡æ/¨H)
  • Large LCD display
  • Data hold and Max hold
  • Auto power off
  • ¡°OL¡± over-range indication
  • ¡°BAT¡± low battery indication
  • Complete with K-type temperature Probe, IR temperature probe, %RH probe, dB probe, Anemo probe, and 9V battery.
  • Dimensions/Wt.: 200X 77 X 50mm/412g
