AMETEK PROCESS INSTRUMENTS PRODUCT DATA SHEET 303B Moisture Analyzer Highly accurate portable measurement of trace moisture in gas streams for Division 2 areas Based on Faraday's Laws of Electrolysis, the 303B absorbs and electrolyzes moisture down to fractional parts per million (ppm) and is linear to its 2000 parts per million by volume (ppmv) maximum reading. An electrolytic cell does not require calibration and is virtually specific to water, so it can be used to monitor the moisture content in nearly any background gas. Versatile The unit is compact, lightweight, and suitable for both portable use and permanent installation. The 303B is available with a choice of power sources covering AC, external DC, and internal battery operation. Fast, accurate measurement The 303B can be situated close to the sample tap, eliminating long tubing runs and reducing the sample transport time of the process gas which improves the overall measurement response time. The 303B transmits the moisture level to a recorder or control center via its 4-to-20 mA output. Built-in bypass flowmeter A built-in bypass flowmeter increases total sample flow to reduce response time. This bypass feature is valuable when the 303B is in portable service - for example, rapidly analyzing moisture in gas cylinders, where it is essential to purge valves, regulators, and tubing of atmospheric moisture prior to taking measurements.
