| The hand held instrument is portable robust and water resistant. This instrument is unique in that it may store up to five user calibrations and so can be used to monitor almost any dye or marker test that is coloured in any fuel matrix. With this increased flexibility comes the opportunity to calibrate the instrument exactly to customer specification. |
