Sightglass eliminates two-port expense

Northvale, N.J.—The Series SLEX/NW light/sightglass combination eliminates the expense of a second sightglass normally used in view the contents of a processing vessel in a hazardous classified location. The device supplies both lighting and the ability to view contents through a single unit, reducing the cost of installation. The SLEX-100 is explosion-proof UL-844 and C-UL/CSA C22.2 No 137 listed. The corresponding Series NW sightglass offers glare-free illumination at the viewing port. Several models are available, offering a number of diameters. All models operate on 115 volts and provide 100 watts of lighting.www.papailias.comPapailias Inc.
