for a more healthy environment The ability to monitor minute airborne particles is critical to the successful control and protection of environmental quality. Hiac/Royco comes to the rescue with individual particle counting at the 0.1 p m level, a level lower than you can get from any other manufacturer. And in our Model 236, you get it in a package that’s compact and completely portable, yet highly versatile as well. This unique laser-based instrument provides 16 accumulating memory channels with a dynamic size range from 0.1 k m up to 6 p m with data presentation in either differential or cumulative mode. All this and a concentrationcapability of up to 50,000,000particles per cubic foot. Operating controls are front-panel mounted for ease of use. There’s a selectable 6-digit display for channel particle counts and a built-in data printer.The 236 also offers an RS232C serial communication output and an output for graphic display. We’d like to tell you more about our Model 236. Please call or write.
