TE-PRO-CAL Low Volume Air Sampler Calibrator SKU: TE-PRO-CAL

The TE-PRO-CAL is an advanced low volume calibrator designed to calibrate low-volume air sampling equipment such as the TE-Wilbur low volume sampler, the BGI PQ200, Thermo Partisol and other low-volume instruments that operate at 16.67 lpm. This portable, battery-operated calibrator provides NIST-traceable flow verification for environmental professionals conducting EPA-compliant ambient air quality monitoring.

Precision Venturi Technology

The system utilizes a precision-machined venturi to generate a differential pressure proportional to the flow rate that is not affected by temperature variations or humidity. This venturi-based approach eliminates the need for temperature and pressure corrections that can introduce calibration errors in field conditions. The calibrator is mounted directly to the sampler's inlet downtube for easy use and quick calibration of field instrumentation.

Key Specifications

• Flow rate range: Optimized for 16.67 L/min (1.0 m³/hr) low volume samplers
• Power: 4 AA batteries for portable field operation
• Accuracy: NIST-traceable calibration for regulatory compliance
• Temperature compensation: Built-in venturi design eliminates ambient corrections

Compatibility

The TE-PRO-CAL is specifically designed for low volume air samplers operating at 16.67 lpm, including:

• Tisch Environmental TE-Wilbur samplers (all PM configurations)
• BGI PQ200 ambient air samplers
• Thermo Partisol series low volume samplers
• Other EPA-approved low volume instruments meeting 40 CFR Part 50, Appendix J and 40 CFR Part 50, Appendix L specifications

Calibration Requirements

EPA regulations require calibration of the sampler's flow measurement device to establish traceability to a primary standard, using a flow rate transfer standard calibrated against a primary flow or volume standard. The TE-PRO-CAL meets these requirements by providing NIST-traceable calibration verification for PM10 and PM2.5 monitoring applications.

Complete Calibration Kit

The TE-PRO-CAL is shipped with the calibrator, a NIST traceable calibration certificate, 4 batteries, filter temperature probe and rugged carrying case. This complete kit ensures field technicians have everything needed for accurate, compliant flow verification without additional equipment purchases.

Applications

• EPA-compliant PM10 and PM2.5 ambient air monitoring
• NAAQS compliance verification for state and local agencies
• Environmental consulting and industrial hygiene monitoring
• Research applications requiring validated flow measurements
• Quality assurance programs for air monitoring networks
