DESCRIPTION:
The flow, temperature and relative humidity are set to the desired level using direct reading dial potentiometers. Air flow is measured and controlled using an electronic mass flow controller. A temperature humidity sensor measures the actual conditions. The electronic signals from the sensor form a feedback loop to the controller circuit board. This unit activates heaters in a water reservoir and the humidified air stream to attain and maintain the temperature and humidity conditions. Control functions require no operator intervention except for periodic calibration. All parameters can be observed visually on digital panel meters or monitored with a strip chart recorder. Cooling below room temperature can be achieved using
cooling option CP-200.
All HCS-501 series systems
control ambient +2 to 35oC (or 20 to 35oC
with cooling option) and 20 to 85% RH at 25oC.
They come complete with regulators. All control systems
use 120VAC, 50-60 Hz.

APPLICATIONS:
The model HCS-501 series Flow-Temperature-Humidity Control System can be used to produce extremely stable atmospheres for water retention measurements in carbon, gas, sorbents, and desiccants. In addition, this system can produce environments for measuring the effects of humidity on materials, coatings, and gas sensors.
Benefits of the 501 system include improved flow rate accuracy +/-2%
from 20% - 100% of full scale. Also, PROM uChip control
leads to tighter control of temperature and humidity.
The Model 501 can produce dynamic mixtures with any other gas or vapor desired. Applications include calibration of field and laboratory gas detection devices, calibration of dosimeters and detector tubes, determination of recovery efficiency in sampling tubes and dosimeters, and evaluation of activated carbon service life.
This cost-effective package (20" x 20" footprint) can be
used as a generator/controller for a variety of
temperature-humidity chambers, in which products,
packages, materials, or other test organisms are to be
exposed to a specific temperature/humidity regimen. The system can also be used for animal and plant exposure studies. |
