Elcometer 355 Coating Thickness Gauge

The Elcometer 355 Coating Thickness Gauge's watchwords are accuracy, simplicity, versatility and durability making this a true state of the art hand-held measuring system packed with time-saving and cost-cutting features.

Available as a standard and top model, the unit’s large memory stores up to 10,000 readings in batches and data can be output to PC, datalogger or printer as required.

With a comprehensive range of Probe Modules available, simply select the most appropriate for the application. All modules are supplied with calibration foils.

  • ±1% or 1µm accuracy whichever is greater
  • Rugged aluminium case designed for the toughest environments
  • ElcoMaster® software supplied
  • Full statistical analysis - mean standard deviation, number of readings, highest and lowest value
  • RS232 output
  • Date and time stamp

Each coating thickness gauge is supplied without a probe allowing the choice of the correct probe for the relevant applications.
