66 -- COMBUSTIBLE GAS AND OXYGEN ANALYZER SOL N68335-97-RFI-710 DUE 070197 POC Chuck Adler Code 233CA, (908) 323-5198. Contracting Officer is D. McClure. The Naval Air Warfare Center Aircraft Division Lakehurst is seeking sources and/or information on a combustible gas and oxygen analyzer. The combustible gas and oxygen analyzer is to be a portable handheld commercial off the shelf (COTS) gas analyzer to detect, measure and indicate concentration of oxygen and combustible gas emitted from JP-5, JP-8, JA-1, JA-1A or similar military or commercial jet fuels. The analyzer shall measure and display the gas concentrations in the following units: oxygen in percent by volume, and combustible gases by percent Lower Explosive Limit (LEL) and Permissible Exposure Limit (PEL) in parts per million (ppm). Descriptive literature should specify the accuracy (e.g +/-5ppm, +/-0.5 percent oxygen, etc.) and resolution (e.g. % Oxygen in 0.1% increments, LEL in 1% increments, ppm in 20 ppm increments, etc.) of the analyzer. The range of oxygen and combustible gas concentration the analyzer can measure or indicate should also be included (for example, 0-30% Oxygen, 0-100% LEL and 0-5000 ppm). The analyzer shall have audible alarms for low and high oxygen concentrations, high ppm and percent LEL for combustible gases, as well as low battery and sensor malfunction. The audible alarms shall be supplemented with additional alarms (e.g. visual indicators) for working in high noise environments. The analyzer shall not be greater than 26 centimeters in any direction with a maximum volume of approximately 5000 cubic centimeters. The weight of the unit shall be less than 3 kilograms. The analyzer shall operate on standard commercial alkaline batteries (i.e AAA, AA, A, C or D size cells). The analyzer shall draw air samples from remote locations by using an automated sampling pump and a minimum 2 meter length sampling hose. The sampling hose shall be constructed of non-fuel absorbent material and contain features to prevent liquids from being drawn into the system. In addition, the system shall be supplied with a calibration kit. The kit shall include all necessary items to calibrate the unit and a carrying case to hold all the kit's elements and the gas analyzer as well. The calibration controls or adjustment devices shall be incorporated in locations easily accessible by the user. The system shall be certified to be instrinsically safe for use in Class 1, Division 1, Group A, B, C and D atmospheres by a nationally recognized testing laboratory. Those sources who are interested in this Request For Information are invited to submit their information and a description of any currently available product that meets our requirements. This is NOT A REQUEST FOR PROPOSAL AND NO SOLICITATION IS AVAILABLE. The Government shall not pay for any information requested in response to this RFI nor will the Government compensate any respondent for any cost incurred in developing the information provided to the Government.
