Dissolved Oxygen Meters & Sensors

The City of Grand Junction is seeking to purchase dissolved‑oxygen (DO) meters, oxidation‑reduction potential (ORP) sensors, and associated cabling for water‑quality monitoring. Three vendors were invited, with two submitting price quotes ranging from roughly $1,000 to $3,600 per line item. The solicitation opened on November 27 2018, but no closing date or award information is provided. This opportunity is suited for manufacturers or distributors of scientific instrumentation who can supply calibrated DO meters, ORP sensors, and related accessories, possibly in modest quantities. • Required equipment: DO meters, multi‑channel ORP sensors, and cable assemblies. • Potential contract value appears modest (under $10 k per vendor based on quoted prices). • Open to nationwide vendors; no explicit geographic restriction beyond the City of Grand Junction.
