This document is a Request for Proposal (RFP) from the National Institute of Standards and Technology (NIST) for a portable, relative, precision gravimeter. The solicitation seeks one quartz-based (non-clamping) gravimeter to be used for determining gravity and gravity gradients for the NIST Kibble balance, with specific technical requirements including a 0.1 microGal reading resolution, automatic corrections for solid earth tides and instrument tilt, and remote operation via Bluetooth or WiFi.

The contract specifies delivery within 90 days to NIST Gaithersburg, with payment of 100% upon installation and acceptance. The instrument must meet detailed specifications such as having more than 2 GB of internal memory, dual batteries, total weight under 15 lbs, and will be subject to inspection within 15 business days of receipt. The contractor must provide a minimum 1-year warranty covering parts and labor, and the device will be used in the Physical Measurements Laboratory for realizing the unit mass for the United States using a Kibble balance as part of the Revised SI standards.
