DEQ AQ LEAD Nephelometers

The State of Oregon, through the Department of Administrative Services on behalf of the Department of Environmental Quality, is soliciting bids for the sale and support of up to 50 integrating nephelometers for ambient air measurement. The equipment must be certified as a Federal Equivalent Method by the USEPA for PM2.5, measure in at least two wavelengths, include an internal sample heater, and be user-calibratable using gas standards. Additionally, the devices must be compatible with EnviDAS data acquisition software. The contract includes requirements for technical support and repair services if DEQ staff cannot perform them. The initial order is expected to be for up to 20 units with a preferred delivery date of April 30, 2027. The contract will be awarded to the lowest responsive and responsible bidder based primarily on the price of the 50 nephelometers, while discounts for accessories and replacement parts will be included but not used for award determination. Bidders must comply with various Oregon Revised Statutes, including non-discrimination, wage laws, and the maintenance of a written sexual harassment and discrimination policy. The agency maintains a 15-day inspection and acceptance period upon delivery, with a 45-day payment term following invoice approval. The solicitation is managed via the OregonBuys portal with a response deadline of November 17, 2026.
