PDI Quality Statement: Pride In Workmanship And Service

Always at the forefront of technological development in surface measurement systems, Precision Devices, Inc. introduces the completely new modular Series 800 Surfometer.

All 800 series models utilize the same basic hardware, with model difference determined by the software installed. Starting with the basic Multiple Parameter system (12 roughness parameters). The units may be upgraded for future needs by simply adding parameter modules.

Simplicity is also inherent in the operation of the instrument, with prompts to guide the operator as the system gathers data, calculates the results and automatically displays the selected parameters, cutoff and system settings. The amplifier is equipped with a 7-inch diagonally measured LCD display. The display is bright and has a wide viewing angle, making it easy to read from any angle.
