66 -- PRECISION DIGITAL THERMOMETER DUE 020200 POC Contract Specialist, Julie Middlebrooks, (256) 876-4152 or Contracting Officer, Shirley Hill (256) 842-7436. This requirement is for 15 Precision Digital Thermometers w/1 manual each. Delivery is required 90 days after award. An evaluation shall be performed to determine if each proposal is technically acceptable. A technically acceptable proposal must clearly show that the offeror can meet the minimum requirements of the Government. Each proposal will be reviewed to assure that each function included in the specification is addressed in the proposal. This procurement is 100 percent Small Business set-aside, restricted to small businesses. The Standard Industry Code is 3829. Therefore, each offeror must respond to each functional requirement of the specification. Description: PRECISION DIGITAL THERMOMETER. Total Error of Resistance Measurements: Shall be less than or equal to (+) or (-) 10 parts per million of reading any resistance between 15 and 400 ohms. Total Error in Resistance Measurement at 25 ohms or at 100 ohms shall be less than or equal to (+) or (-) 6 parts per million. Note: If the thermometer requires the routine use of an external resistor or resistors in order for it to make measurements within the specified total error limits, then the thermometer is unacceptable. Computer and Peripheral Interface Ports: One each IEEE-488, RS-232, and parallel interface ports are required. Display: Backlit Color Liquid Crystal Display (LCD). Display of Measurements: The thermometer shall be able to display measurements of temperatures in degrees C, K, or F, resistance in ohms, and the ratio of probe resistance to reference resistance. Display resolution shall be 0.0001 degrees C or better when a 25 ohm probe is connected. Resistance-to-Temperature Conversion Formulas: Shall be user-selectable. Current Source: The source current (excitation current for thermometer probes to be connected) shall be front panel programmable from 0.0001 microamps to 10 milliamps. Probe setup and Calculation of Constants: The thermometer shall allow the user to program by probe serial number into the thermometer's internal memory the following information: at least 10 unique probe setups of probe constants, resistance-to-temperature conversion formula, excitation current, and the value of the reference resistance. Automatic Calculation of Constants: The thermometer shall be capable of automatically calculating the constants required for International Temperature Scale of 1990 temperature computations by allowing the user to connect his uncalibrated standards type probe to it, measuring the resistance at fixed points or against a calibrated standard. The thermometer shall make the resistance measurements, calculate the constants for the probe, then store them into memory. Floppy Disk Drive: The thermometer shall have a built-in 3 inch floppy disk drive for storing readings into memory in ASCII format. The format for storage onto 3 inch disk media shall allow the user to manipulate the stored measurement data in graphing and spreadsheet applications software running on his external computer. Electrical Power Requirements: The thermometer shall be powered by 115 VAC (+) or (-) 10%, 60 Hertz. Probe Input Terminals and Connectors: The thermometer shall have a sufficient number of 4-wire terminals to simultaneously enable the user to connect at least five different 4-wire probes. The terminals shall use gold plated connectors that are compatible with bare wire, spade lugs, and banana plugs. See Note 1***** Posted 01/20/00 (W-SN417166). (0020)
