Sampling Flow Rate L/min － 3 to 5 Using a fixed orifice purge.
  1. Pressing the display switch alternates display between humidity and dew point.
  2. The dew point is a calculated value based on temperature and humidity.
  3. The calculated dew point precision value at the time the product is shipped. This is not a guaranteed value.
  4. The MG40 is a dew point monitor intended for use with atmospheric pressure air. If taking a measurement, place the sensor directly in the air to be measured.
  5. The MG40A-P is a dew point monitor intended for use with compressed air. If taking measurements, then supply the air to be measured to the product via the included sampling air tube (Φ4, L2000).
  6. Using or storing in the following atmospheres will lead to deterioration of the sensor and necessitate recalibration in a short period of time:acetic acid, hydrochloric acid, ammonia, ethyl acetate, xylene, butanol, ethylene dichloride.
