Sulfur dioxide monitor
New stack monitor allows continuous in-stack monitoring of sulfur dioxide through application of correlation spectroscopy. Output is directly readable in ppm and can also be interfaced with conventional chart recorders. Combustion 64 Equipment Associates, Inc.
#NNVLAR FLOW PATH
Combustion tips
Chromatographic valve
Tantalum valve for gas chromatographs are acid resistant, allowing analysis of highly corrosive substances such as wet chlorine or acid gases. Valve is leak proof, has zero dead volume and no “memory.” Various sample loops from 60 p1 to 2 ml are available. Carle Instruments, Inc. 61
Ram Pulse Igniter keeps pilots in gas flare stacks burning even under adverse conditions. Gas-air feed to igniter can be either automatic or manual. Robert R. 65 Clarke Co.
VR SERIES
Silencer Smoke monitor
Light transmissometer measures dust and smoke emissions in-stack in large fuel combustion installations, incinerators, cement plants, and other industrial facilities. Air-flushing attachment keeps lens clean. Lear Siegler, Inc. 62
Tape samplers
Amtype tape samplers are designed to collect samples continuously over preset time intervals. Sampling technique comforms to ASTM D170 test method. Wallace-Fisher Instrument Co. 66 Combustion tester
Series 3400 combustion tester can be used for boiler efficiency studies, flue gas analysis, and safety/hygiene monitoring of work areas for hazardous gas buildup or oxygen deficiency. Meter is semi67 portable. Scott Aviation Ir analyzer
infrared analyzer measures hydrocarbons dissolved in water using carbon tetrachloride extraction method. Sensitivity is about 1 ppm using 1-cm path cuvette. Wilkes Scientific Corp. 68
MIRAN
a Portable analyzers
New line of automatically temperaturecompensated units measures pH, conductivity, temperature, dissolved oxygen, redox potential, chloride, turbidity, and pressure. All instruments have AC/DC circuitry as standard equipment. 63 Aquatronics, Inc. 282 Environmental Science & Technology
Particle detector
Eduquip particle detector measures particles down to size of condensation nuclei. Device is intended as a teaching tool. Eduquip, Inc. 69
Atmospheric silencer attenuates noise from high-pressure venting. Silencer features two-stage inlet diffusion, which raises low frequency noise to higher frequencies within the device’s optimum frequency range. Unit boasts 60-dB dynamic attenuation in 2000-Hz band. Kittell Muffler and Engineering, Inc. 70 Pitot tubes
Comprehensive line of pitot tubes allows measurement of gas velocity and direction in hot environments, with watercooled models rated as high as 3270°F. Land Instruments, Inc. 71 Mercury analyzer
New semiautomatic system determines mercury concentrations as low as 0.2 ppb routinely and rapidly. Unit is an accessory for Beckman atomic absorption and ultraviolet spectrophotometers. 72 Beckman Instruments, Inc.

in the industry. What you see is what you get - fast. With money-saving FOB delivery coast to coast. Five plants in key geographic locations, one near you, mean you save money on FOB delivery charges. Five hundred Linde Distributor service locations see you get local service, too. And we see that what you get is A-1, because we manufacture most of the gases we sell. Because we’re Linde. A Division of Union Carbide Corporation, a company with over 50 years experience making industrial gases. Nobody has greater quality control because no gas manufacturer makes more of its own gases than we do. The proof? 57 pages cataloging gases for every lab requirement. Plus 40 pages of control equipment. Seven pages of cryogenic containers. And a page on cryogenic fluids. Color-coded by sections. Complete with index, glossary and safety information.
