Description
The Air Force Test Center is seeking sources to provide commercial equipment, specifically dew point hygrometers, that meet the technical specifications outlined in the document. The required equipment must have a primary method, multi-stage chilled mirror sensor, and be able to measure dew/frost point temperature with high accuracy. The equipment should also have a remote-mounted configuration, standard chromium/chrome mirror surface, and be able to cover a dew/frost point range of −70 °C to +95 °C. The contract requires a minimum one-year warranty on all parts, sensors, and labor.
Key features of the required equipment include:
• Multiple user-configurable/scalable analog outputs
• Dedicated bi-directional RS-232 serial interface for data acquisition and remote programming
• Minimum two programmable, form C SPDT dry-contact relays rated for process alarms
• Universal power supply accepting 90 to 230 VAC (±10%), 50/60 Hz
• NIST-traceable certificate of calibration performed by an ISO/IEC 17025 accredited laboratory
