NUMBER 1 IN LUBRICANT CONDITION MONITORING WaterTest™ Kit DETERMINATION OF WATER CONTENT INTO OILS, FUELS AND SOLVENTS Method derived from the ISO9114:1997 standard WaterTest™ Kit is based on the ‘’Aquatest’’ water in oil analysis method which is (2) (3) (1) standardized by ISO ,AFNOR and GFC and which was continuously refined by GESERCO over the past 50 years. The GESERCO WaterTest™ test kit allows for simple, fast and cost effective determination of the water content. Works even for analysis of lubricants with a high additive content, without interfering with the analysis result Immediate evaluation of results: in 3 min 2 modes : MBP: Free water mode NTH: Free and dissolved water mode Can be used for: mineral oils and petroleum distillates synthetic oils and lubes bio lubricants and bio fuels vegetable oils aromatic fluids alcohols solid solvent soluble products (greases…) Non-hazardous reagents Robust case 3 ranges from 0 – 15 000 ppm H₂O and 0 – 20 % H₂O Reliability of results Field kit User-calibratable without returning to factory ISO 9114 :1997 standard | (2) NF T60-640 standard, June 2018 | (3) GFC TR-40-A-14 method, December 2014 SPECIFICATIONS MAY CHANGE WITHOUT NO

A high-performance measuringprinciple The Wateriest™ Mallette is a field “Aquatest”, a water content analysis technique standardized by ISO, AFNOR and GFC. A reagent transforms each water molecule present in the sample under test into a gas. The quantity of gas released produces a pressure exactly proportional to the water content. The pressure is measured by a latest-generation sensor, converted into %H20 or ppm H20 and displayed. The Rapid Oil Test Gauge in the Wateriest kit offers a simple and effective water monitoring solution. Not only does it enable precise measurement of water content...
