– Integrated memory for the results of up to 40,000 measurements and 30 profiles
– Integrated thermal printer with high print quality
– Data transfer of results and profiles via USB interface to your PC
– Evaluation of most common parameters as well as characteristic curves, parameter lists (e.g. material ratio curve)
– Tolerance monitoring
– Printing of R-profile (ISO/ASME/JIS), P-profile (MOTIF), material ratio curve, measuring record
– Setting of asymmetrical intersection lines for peak count calculation
– Measuring units (metric / inches) and standards (ISO/JIS/ASME/MOTIF) are selectable
– Individual sampling lengths and short cutoff can be selected
– Lock for instrument settings
– Built-in rechargeable battery with power management
– Suitable for use with stationary measuring station
– For use with PHT probe range
– MarSurf PS1/M 300 Explorer software for recording measurements
