About this file
This document is a set of Salient Characteristics for a federal contract opportunity for Digital Temperature Cables and Accessories. The key requirements include:
7 ea. Digital Temperature Cables with 13 temperature sensors along a 7.1m cable, capable of operating from -50 to 120°C with +/- 0.1°C accuracy, and interfacing with RS-232/RS-485/SDI-12 data loggers. 7 ea. SDI Communication Interfaces compatible with the sensor cables, 1 ea. Rigid Temperature Probe with 19 sensors along a 3.3m length, and 1 ea. Portable Compact Data Logger with 32MB storage and wireless Bluetooth.
The related federal contract opportunity, Solicitation Number 140G0124Q0293, is for the delivery of these Digital Temperature Cables and Accessories to the U.S. Geological Colorado Water Science Center in Denver, CO within 30 days. This is a total small business set-aside with a NAICS code of 334513 and a size standard of 750 employees. The Request for Quote is due on or about 9/09/2024 and the anticipated award date is 09/19/2024.
