• Description:
  "The Bureau of Mines examined the effects of high humidity and water droplets on the GCA Corp. real-time aerosol monitor (RAM-1), which used a 10-mm cyclone preseparator. Tests were conducted both in a laboratory and in a full-scale model mine entry. The laboratory tests were conducted in a test chamber saturated with moisture and water droplets. Under these extreme conditions, the ram-1 responded by indicating dust concentrations of 1 1/2 to 2 mg/m3, although the air was dust free. Within the first 2 h of each test, water accumulated in the cyclone and affected the cyclone particle separation characteristics, resulting in readings of 3 to 4 mg/m3. In addition, condensation formed inside the ram-1 case and affected the liquid crystal display. However, the full-scale mine entry tests revealed that the RAM-1 can function acceptably in an atmosphere of water vapor and water droplets similar to the most severe conditions found in an underground mine." - NIOSHTIC-2
