ALLA FRANCE , made in France Calibration reliability : We took several years to put in place an automatic hydrometer calibration system. Even if error remains possible, the human error probability is excluded at 99.5% . Traceability : Every standard hydrometer has an individual number printed on the scale. This number is stocked in our database and fully traceable to our primary MRA master. The material used to fix the ballast respects 100% the most stringent requirements specified by official standards, namely to be placed horizontally at 80C, for 1 hr without melting. Every instrument has reference mark at the top of scale and a small but visible cut on the glass. The purpose of this reference mark is to enable the user to detect if the scale has moved after a shock, or with the passage of time. Marks : The scale of the hydrometer is fully marked with all the reference norms and international correspondences. Scale : The conception of the scale enables a very easy reading, marking clearly the difference between the divisions and subdivisions. When the official standard permints us, we print a double scale enabling the user to read the density whatever the position of the hydrometer inside the cylinder.
