## Description

The National Physical Laboratory \(NPL\) is the UK's National Measurement Institute and is a world-leading centre of excellence in developing and applying the most accurate measurement standards, science, and technology available\. The National Physical Laboratory \(NPL\) requirement is for a water vapour analyser, with the following capabilities: 1\. capable of accurately measuring water vapours \(see specification for amount fractions\) in pure oxygen gas\. 2\. The analyser shall be CE/UKCA certificated\. 3\. Possibility to be networked and remotely accessed \(minimum 100-1000 Base-T Ethernet\) 4\. Have a serial RS232/485, Modbus TCP connectivity\. 5\. Required to operate at standard UK mains power supply \(230Vac, 50Hz\)\. 6\. Analog output \(4-20 mA or 0-10 Vdc\) is required to allow connectivity to exiting automatic analysers and LabView integration\. 7\. A local data storage \(e\.g\. on flash drive\) is desirable\. 8\. Inlet pressure: 2-9 bar a 9\. Flow rate 0\.05-1\.5 slpm 10\. Gas temperature up to 60⁰C 11\. Wide dynamic range: over four orders of magnitude \(see specification\)
