Variable Flow Calibration Kit for TSP/PM10/PM2.5 Hi-Vol Air Samplers (20-60 CFM)
The TE-5028 Variable Flow Calibration Kit delivers precise flow verification for high volume air samplers operating at 20-60 CFM. This complete calibration system ensures your TSP, PM10, and PM2.5 samplers maintain EPA-compliant flow rates required for accurate 24-hour sampling periods, where average particulate concentrations are determined by dividing filter weight gain by total volume of air sampled, corrected to EPA standard conditions (25°C and 760 mmHg).
Complete Calibration System
The kit includes all essential components for field calibration: calibration orifice with certificate, 0-30" slack tube water manometer, top load adapter plate, connecting tubing, and protective carrying case. Calibration equipment performance must be guaranteed to maintain data quality for regulatory compliance.
Key Specifications
- Flow range: 20-60 CFM (34-102 m³/h)
- Manometer range: 0-30 inches water column
- Includes NIST-traceable calibration certificate
- Portable design with protective carrying case
Compatibility
This calibration kit works with all Tisch Environmental high volume air samplers including TSP, PM10, and PM2.5 configurations. Compatible with TSP samplers operating at 39-60 CFM flow rates and PM10/PM2.5 size selective samplers using US EPA reference inlets. The variable flow design accommodates different sampler configurations and operating conditions.
Calibration Requirements
Maintaining correct design volumetric flow rate through the inlet is critical for proper particle size cutpoint performance, with specific design flow rates specified by manufacturers. The TE-5028 enables verification of flow accuracy across the full operating range of high volume samplers.
Annual Recertification
NIST traceability requires annual recertification of calibration equipment. Calibration checks must verify values agree within specified tolerances. Contact Tisch Environmental for recertification services to maintain equipment certification and data validity.
Applications
Essential for EPA-compliant ambient air monitoring programs, regulatory compliance verification, and quality assurance protocols. TSP measurement continues for specific applications including lead monitoring in accordance with 40 CFR Part 50, Appendix B, while PM10 and PM2.5 monitoring supports NAAQS compliance requirements.
