Calibrators

The Texas Commission on Environmental Quality (TCEQ) Air Monitoring Division has issued Request for Bid (RFB) 582-26-15242 for the procurement of specialized laboratory calibration and air quality monitoring equipment. The solicitation requests six line items consisting of Teledyne brand instruments: a Dynamic Dilution Calibrator (Model T700U), three Mass Flow Controllers (MFCs) with varying specifications, a UV Photometric Ozone Calibrator (Model T703U), and a High Performance Zero Air System (Model T701H), with quantities of two units each for the first five line items and one unit for the final item. The ozone calibrator must meet stringent performance standards including linearity of 1.0 percent of full scale, precision of 1.0 parts per billion (ppb), a response time of 240 seconds to 95 percent, and seven-day stability parameters, with an internal photometer providing closed-loop feedback control and battery-backed-up electronic clock capabilities. Bidders must provide unit pricing and extension pricing for each line item, with delivery timeline and cash discount information available as preferences for evaluation. The deadline for submission of written questions is February 18, 2026 at 12:00 PM CST, and bids must be submitted electronically to TCEQebid@tceq.texas.gov by February 25, 2026 at 2:00 PM CST, with the solicitation number, company name, and due date included in the subject line. All bidders must possess an Employer Identification Number (EIN) prior to contract award and payment, and all bids must be manually signed to avoid disqualification.

Bidders claiming Texas residency must qualify as Texas Bidders under 34 TAC Rule 20.32(68), and the procurement includes preferences under Texas state law for historically underutilized business (HUB) participation and small business set-asides, though the evaluation determined that no subcontracting opportunities exist for this contract. However, if respondents identify subcontracting needs, they must notify TCEQ immediately and submit a HUB Subcontracting Plan to remain responsive. All bidders must comply with certifications regarding Israel boycott compliance and non-engagement with Iran, Sudan, or foreign terrorist organizations, and the contract is subject to Texas state law and TCEQ terms and conditions. "Or equal" alternatives to the specified Teledyne brand equipment are permitted, allowing qualified vendors with equivalent capabilities to submit competitive bids. The solicitation documents do not specify the total award value or budget range; however, interested vendors should note that two units each of five line items and one unit of a final item represent the procurement quantities for which pricing must be calculated.
