with probe is available in several velocity ranges with logarithmic scale to, permit expansion for lower velocities. C a n be used for other gases as well as air. Hastings-Raydist 64 Cooling systems

Phenols test kit

Simplified version of “Standard Methods” colorimetric test for phenols uses patented vacuum-reagent ampuls to eliminate usual problems of reagent handling and stability. Reliable results can be obtained by nontechnical personnel in less than a minute. CHEMetrics, Inc. 61

Modular evaporative cooling system uses sonic atomizing nozzles to inject a fog of ultrafine water droplets into hot gaseous effluents. Typical applications include smelters, waste incinerators, generating stations, and kilns. Sonic Development Corp. 65

Visible emissions monitor

Low-maintenance visible emissions monitor has electronic components housed in weatherproof case and yields readout in percent opacity on a meter or, if desired, o n a recorder for permanent records. Finds application in stack monitoring. Leeds & Northrup 69 Combustible gas monitor

Recorder

Compact instrument will detect gasoline, propane, methane, smoke, carbon monoxide, and most common industrial solvents with solid state sensor that will not burn out in high gas concentration. Remote sensor activates alarm, and meter indicates concentration levels. International Sensor Technology 70

Portable battery-operated unit employs sonar to measure and record the level of any liquid waste without actually contacting the waste stream. Corrosion resistant PVC sensor is not subject to 62 buildup. C. W. Stevens, Inc.

Organic carbon analyzer Ion exchanger

Commercial size fluidized bed ion exchange unit can continuously treat 600 gpm industrial liquid waste. Water can be recycled or safely vented to public waterways. Liquitech, Inc. 66 Oil/water separator

Clarifier

Compact waste water treatment system provides economical separation of emulsified oils from industrial and commercial process discharges. Unit adapts chemical coagulation and air flotation principles to clarify water a t rates of less than 20,000 gpd. Tenco Hydro/ Aerosciences, Inc. 63 Velocity meter

Air velocity meter boasts newly designed probe that features small diameter noncorrosive tubing as sensing element instead of delicate wires. Meter

Separator is designed to remove oil from water where oil content is greater than 25 ppm. Unit uses system of regulated compartmentation, leveling gates, and controlled flow to separate liquids. Flow rates from 10-1000 gpm available. Automatic Filter Systems, Inc. 67

Direct reading instrument gives rapid measurement of total organic carbon and total carbon in water. Instrument determines carbon content directly, not by difference, from single sample. Uses chemical oxidation followed by nicke1,’hydrogen reduction and hydrogen flame detection of methane produced. Envirotech Corp., Dohrmann Div. 71 Airport pollution monitor

BOD instrument

Mobile monitoring system aids in developing program for dealing with noise and air pollution generated by airport traffic and aircraft emissions. Instrument Systems Corp. 72

Electronic instrument measures BOD of waste water by measuring pressure decrease in head space as microorganisms deplete oxygen supply in test flask. Mechanical sensor activates a cell which generates oxygen electrolytically until pressure is restored to equilibrium value. Ecological Controls, Inc. 68
