Description :
Model CKHV and Model CKHV810 High Volume Calibration Kits are designed for use with Staplex® Model TFIA, TFIA-2 and TFIA-4 High Volume Air Samplers and allied instruments. The Calibration Kit offers a fast and affordable calibration procedure
that maximizes the accuracy of all air sampling results by calculating the true
flow rate of a particular High Volume Air Sampler.
Model CKHV High Volume Calibration Kit is used with High Volume Air Samplers equipped with 4 inch (10.16 cm) diameter Filter Holder Assembly and includes a Calibration Orifice prescribed for use by the U.S. Environmental Protection Agency,
a water manometer, a series of resistance plates, and a carrying case.
Model CKHV810 additionally includes an 8 inch by 10 inch (20.32 cm X 25.40 cm) Adapter for use in calibrating whenever 8" x 1 0" Filter Holder Assemblies are used
on the Air Samplers. Model CKHV81 0 can also calibrate while such samplers are mounted in a Staplex® SAM Aluminum Outdoor Shelter or similar shelter.
Special 8" X 10" Adapter is available separately as Part No. AD810 Adapter and can convert Model CKHV to calibrate Samplers using 8" X 10" Filter Holders. Similarly, removal of Adapter from Model CKHV810 allows calibration of Samplers using 4" diameter Filter Holders.
Principle of Operation
The Calibration Orifice and manometer unit are factory calibrated on a
Standard Positive Displacement Rotary Type Meter,
The airflow vs. static pressure data are used to plot an Orifice Calibration Curve,
which is furnished with each Staplex® Calibration Kit.
The water manometer is center-mounted between columns to eliminate parallax,
and has a sliding zero adjustment. The vinyl-plastic columns and spring steel
scale are flexible for easy carrying and will withstand rough use.
The Calibration Orifice connects directly to the High Volume Air Sampler or
onto the 8" x I0" Adapter. One leg of the water manometer connects to the
pressure tap of the Calibration Orifice and the other leg remains open to the atmosphere.
Using this arrangement, the High Volume Air Sampler is run at different but
constant airflows for 5 minutes each to simulate the resistance of filters varying
from clean to saturated. The different constant airflows are obtained by simply
placing the resistance plates, one at a time, between the Calibration Orifice
and the High Volume Air Sampler to be calibrated. The manometer water
pressure is converted to Actual flow rate using the curve supplied with
the Staplex® Model CKHV. The Flowmeter (rotometer) reading is also recorded
the data sheet. Using these data, a custom calibration curve is plotted.
This curve is the direct reference to obtain the true flow rate of the
High Volume Air Sampler.
Calibration Recommendations
Staplex® High Volume Air Samplers should be calibrated in this manner when first purchased, after every motor or brush change, anytime the Flowmeter (rotometer) is replaced or adjusted, anytime a one-point audit check deviates more than ± 7% from the custom calibration curve, or at least every six months. U.S. EPA states that users should calibrate the Flowmeters on High Volume Air Samplers at least once a year.
