During the storage period appropriate maintenancerecords will be Before placing equipment in administrative storage, current preventive maintenance checks andservices should be completed. Shortcomings and deficiencies should be corrected, and all modificationwork orders (MWO S) should be Storage site selection. Inside storage is preferred for items selected for administrative storage.

4 Self Contained Kit - no other equipment Instrumented - to eliminate human presence of free WATER within completed in less than 2 light weight-8 fluorescing be recalibrated in the test requires two simple steps, First, a measuredsample of fuel is passed through a paper pad that istreated with sodium fluorescein on its upstream , the pad is compared with a fluorescing stan-dard. WATER droplets that are smaller than the eye can seewill cause the sodium fluorescein to flouresce in ul-traviolet light. The degree of flourescence is greater forincreasing amounts of WATER in the aqua -GLO Kit employs a new approach in thedetermination of the degree of fluorescence (or watercontent). A single, permanent fluorescing standard ispositioned under a photographic-type iris diaphramwhich can be opened or closed to increase or decreasethe amount of ultraviolet determine WATER content, the operator merely ad-justs the diaphram lever arm until the fluorescing stan-dard and the test pad show equal brightness in the ul-traviolet light.

5 This balance is reached when the zero-centering ammeter reads ZERO. The amount of WATER isread in parts per million (ppm) on the diaphram Iever armscale which has been pre-calibrated in the factory. Thescale numbers range from 1 to 12. These numbers areppm if the test sample of fuel that flowed through the padwas 500 ml. However, if WATER content is in the range of 5to 60 ppm, the test sample can be reduced to 100 a 100 ml sample is taken, the operating instruc-tions explain that the scale reading must be multiplied by5 to obtain the WATER content in ppm. Registered In Patent OfficeMANUFACTURED SPECIFICALLY TO PERFORM TESTS PER ASTM METHOD D3240 Patent No. 3500046 Made under licenses from Exxon Research & Engineering Ill was introduced in 1982 with an entirely newlight source. The ultra violet light that was used from1966 to 1982 could not be operated on AC power.

For example, the stan-dard fitting permits direct connection to a quick discon-nect. Another fitting allows the sample to be drawnthrough the test pad with a aqua -GLO Kit is based on a technique de-veloped by the Navy for accurate field determina-tion of the free WATER content of jet fuels. Unlike the Navyequipment, the aqua -GLO Kit requires only onefluorescing standard and is instrumented to eliminatehuman Also in Combination with our MiniMonitorKit for Contamination Testing per ASTM Methods D2276and Bulletin 68-8 (6-80)for details of MiniMonitor KitCOMBINATION KIT MODEL GTP-323In one carrying case: aqua -Glo Series Ill WATER DETECTOR MiniMonitor Contamination TesterAn outstanding feature of the aqua -GLO Kit ispermanency of the fluorescing standard.
