  • Humidity range in SM-Series Humidity Chambers is limited by a +7°C (+45°F) minimum dew point temperature and a maximum dry bulb temperature of+88°C (+190°F). Relative humidity indication at or near the physical limits may be affected by sensor accuracy and control tolerance.
  • Humidity Control Tolerance is measured at a dry bulb temperature above +20°C (+68 °F).
  • Noise Level: A-weighted sound pressure level measured at a distance of 1.0 meter (39.4 inches) from the surface of the equipment at a height of 1.6 meters (63 inches) from the floor in free-field conditions, using a calibrated instrument.
  • Performance is based upon 60Hz and 23.9°C (75°F) ambient air, and may vary slightly at other ambient temperatures. S/SM-Series Environmental Chambers are designed for use under normal laboratory operating conditions. For other applications, please consult Thermotron.
  • Test Chamber specifications are subject to change.
