PRODUCTS & MANUFACTURERS VI
Perfect Sense, Inc
Air quality instrumentation line includes: indoor air quality sensors, controls, and
monitoring TVOC, Temperature, RH, plus toxic gases.
Photocor Complex
Russian developed simple-to-use photon-correlation spectrometer for basic and applied
studies in physics, chemistry, biology, medicine, engineering, and environmental
technology. This includes teaching applications in these subjects. It can measure the size
of particles suspended in liquids in the range from 0.001 to 5 microns without
calibration. Real-time size monitoring like kinetic aggregation process is possible. Due
to optical arrangement, it is possible to measure light scattering in opaque systems
characterized by strong light absorption. Accuracy has been verified by measuring light
scattering in a variety of systems i.e. latex suspensions, aniline dye dissolved in water,
dilute solutions of polystyrene in toluene.
RasCO, Inc
Environmental engineering, consulting and design firm. Water analysis and water quality,
incorporating expertise with membrane technology and associated equipment. Bench-scale
treatability studies as well as design, fabrication, installation, and maintenance of full
scale ROMEM Systems (UF,NF,RO) available. 
Spectrex Corporation
Products available include: 1- Laser particle counter operates with flowing and in-situ
liquids and is ideal for monitoring rates of change, i.e. dissolution or agglomeration.2-
A system equivalent to the log-sector method for spectrochemical analyzers providing both
qualitative rapid-scan analysis and quantitative specific determinations.3- Pocket Bubble
Flow meter for air sampling. 4- air sampler for lead and asbestos. 5-miniature precision
diaphragm pumps for gases.
 Solar Light Co, Inc
Full range of solar ultra-violet single and multi-port simulators, meters, and accessories
for measuring ultraviolet, laser, infrared, and visible radiation. Testing instruments for
measuring column ozone thickness, aerosol optical thickness, precipitable water,
temperature, and humidity. A handheld meter with data logging and integration
capabilities. A Biometer to measure wavelengths or sunburning effect of the total
ultraviolet spectrum.
Surtreat Corporation
