PhotoVac Model HL 2000 MicroTip

Circa 1991

A portable photoionization detector (PID) specifically engineered for detecting and measuring volatile organic compounds (VOCs) and toxic gases in real-time.

Use Cases:

• Hazardous Waste Sites: Extensively used for site characterization and delineating the extent of contamination in soil gas and ambient air. It helps establish perimeters and monitor potentially hazardous conditions during remediation.

• Industrial Facilities: Employed for fenceline and perimeter monitoring at petrochemical plants, refineries, and manufacturing sites to detect fugitive emissions or leaks from solvent storage and piping.

• Emergency Response: Utilized by HazMat teams to quickly characterize accidental chemical spills, leaking gas cylinders, or other hazardous material releases.

• Confined Spaces: Used for pre-entry atmospheric testing in storage tanks, aircraft fuel tanks, and transportation vessels to ensure air quality meets health and safety standards.

• Groundwater & Soil Monitoring: Critical for screening soil and water jar headspace to identify ionizable species and determine vertical or horizontal contamination extent.

• Indoor Air Quality (IAQ): Applied in schools, commercial buildings, and cleanrooms to monitor workplace exposure limits and identify mobile sources of pollution.

Historical Significance:

This model was a pioneering tool for environmental screening and was adopted extensively by local, state, and federal EPA groups for site assessment and remediation efforts. The HL-2000 variant specifically held a UL Classification for use in hazardous, potentially explosive locations (Class I Division 2, Groups A, B, C, and D).
