Sitelab UVF-500D Handheld Hydrocarbon Analyzer

Overview

The Sitelab UVF-500D is a rugged, battery-operated handheld hydrocarbon analyzer built for rapid on-site screening of petroleum contamination in soil, water and sediment. Using ultraviolet fluorescence (UVF) detection, it identifies total petroleum hydrocarbons (TPH) in the C15 to C50 “oil and grease” range, making it especially sensitive to the heavy polycyclic aromatic hydrocarbon (PAH) compounds found in crude oils, heavy fuel oils, asphalt and coal tar. Manufactured for Sitelab by Turner Designs as the direct replacement for the earlier TD-500D, the analyzer brings laboratory-grade UVF screening into a waterproof, field-portable instrument that environmental consultants and remediation teams can carry directly to the sample point.

Where a full laboratory GC or GC/MS analysis can take days to return results, the Sitelab UVF-500D delivers a usable screening-level reading in minutes, right at the drill rig, excavation pit, or discharge outfall. Test results correlate well with EPA Method 1664, EPA Method 9071B, and standard gas chromatography methods, giving field teams a fast, defensible way to triage samples, delineate contamination boundaries, and decide in real time where further excavation or laboratory confirmation is needed. Backed by genuine manufacturer documentation, Seven Star LLC proudly supplies the Sitelab UVF-500D across Oman and the wider GCC, backed by genuine stock, manufacturer-standard calibration data, and responsive local technical support.

Working Principle and Engineering Design

The Sitelab UVF-500D works by extracting a soil or water sample in a solvent, then exposing the extract to ultraviolet light inside the instrument’s optical chamber. Petroleum hydrocarbons absorb specific UV wavelengths and re-emit that energy as visible fluorescence; the intensity of this fluorescence is directly proportional to hydrocarbon concentration. Two independent optical channels inside the Sitelab UVF-500D allow it to distinguish between different hydrocarbon signatures and provide a stable, repeatable digital PPM reading on its integrated LCD display within a few minutes of extraction.

Housed in a rugged, waterproof enclosure designed for field conditions, the Sitelab UVF-500D runs on batteries and requires no external power source, making it equally suited to a marsh, a well pad, or a contaminated industrial yard. The instrument ships factory-calibrated using Sitelab’s own TPH-Oil calibration standards, and a simple front-panel keypad (READ, CAL, STD/VAL, A/B channel select) lets field technicians run calibration checks and sample readings without a laptop or external software.

Key Features

The Sitelab UVF-500D’s dual optical channels give it the flexibility to screen for different hydrocarbon signatures within the same C15-C50 oil and grease range, while its rugged, waterproof housing tolerates the wet, muddy, and dusty conditions typical of remediation and drilling sites. Every unit is factory calibrated before shipment using Sitelab’s CAL-056H-500D TPH-Oil calibration kit, so field teams can begin taking defensible readings immediately without an on-site calibration procedure.

Because the Sitelab UVF-500D correlates closely with EPA Method 1664, EPA Method 9071B, and gas chromatography TPH results, its readings are widely accepted by regulators and remediation program managers as a legitimate field-screening data point, not just a rough estimate. The instrument’s low cost relative to laboratory turnaround and its few-minutes-per-sample analysis time let a single field technician screen dozens of samples per day, dramatically narrowing the number of samples that need full laboratory confirmation.

Industrial Applications

Underground storage tank (UST) closure and remediation projects rely on the Sitelab UVF-500D to screen soil borings and excavation sidewalls in real time, letting field crews decide on the spot whether contaminated soil has been fully removed before backfilling. Produced water and discharge water monitoring at oil and gas facilities uses the instrument to verify that treated water leaving a site meets oil-and-grease discharge limits before release to the environment or a receiving water body.

Marine and coastal environmental teams use the UVF-500D to screen bilge water, ballast water and shoreline sediment for petroleum contamination after spills or routine vessel operations, while port authorities and refineries use it for rapid wastewater and stormwater screening. Environmental consulting firms across Oman and the GCC also rely on handheld UVF analyzers during Phase II site assessments, where fast field screening helps define the extent of petroleum impact before committing to a full laboratory analysis program. Seven Star LLC supplies the Sitelab UVF-500D to laboratories, industrial facilities and research institutions throughout Oman, Muscat and the Sohar and Salalah economic zones, backed by regional stock and manufacturer-standard support.

Technical Specifications

For sites that later need broader hydrocarbon fingerprinting beyond the C15-C50 oil and grease range that the Sitelab UVF-500D covers, Sitelab’s benchtop UVF-Trilogy family adds interchangeable modules for gasoline-range, diesel-range, and PAH-specific detection, giving a consulting firm or laboratory a natural upgrade path once the Sitelab UVF-500D has been used to triage a site in the field.

Field teams across Oman value the Sitelab UVF-500D for its combination of speed and defensible screening data: a technician can move from sample collection to a quantitative total petroleum hydrocarbon reading in minutes without needing a fixed laboratory nearby, which shortens remediation decision cycles on active drilling pads, pipeline right-of-ways, and coastal terminal sites. Because the instrument reports directly in familiar TPH units and stores results for later download, project managers can compile defensible screening logs for regulators and clients without waiting on outside lab turnaround for every sample.
