General instruments corporation manufactures offers elcometer 355. ,following are some advantageous features of this coating thickness gauge include: a rugged hand- held, battery powered and fully portable coating thickness measuring system, from elcometer instruments ltd, uk. This coating thickness gauge is provided this comes in two parts the host instrument, housed in a lightweight but fully protective extruded aluminium case, has a wide range of display memory and output features, and probe modules, providing a flexible and extremely accurate selection of measurement options which are fully interchangeable. Following are some of the technical features of this coating thickness gaugewhich include: probe modules are available for ferrous [f] metal substrates and non ferrous [n] metal substrates with both probe style and thickness range options, allowing the user to select from a list of options those probe modules which are required to meet the demands of the application. The elcometer 355 is available in ttwo forms are available of the elcometer 355. The 355 standard has a 14 keypad control panel and software which allows allowing for auto batching with 25 present batches with up to a total of 5,000 readings in memory. Output can be serial or parallel to printer, personal computer or data logger. Statistical analysis of batches provides aa continuous display of the number of readings are provided by statistical analysis of batches alongside the current thickness value in microns, mil, thou or millimetres and also allows calculation and display on command of the mean value [x], the standard deviation [o], the highest and the lowest readings in a batch of readings. There are some important functions which are performed by this thickness gauge which include: the 355 top has a 28 key control pad and full feathered software including capacity for up to 10,000 readings in batches with up to 7 figure identifications, full statistical analysis including limits and reasonable limits, [this is a new concept for coating thickness gauges], password protection of calibration functions base or zero and cal, date and time free collection of readingsaveraging storage of the average value for varying groups of readings on command and counted average recording of the average of present numbers of readings.
