SPI - Digital Protractor - Anlge Measurement Tool

This protractor provides an immediate digital reading of any angle in a full circle with 0-90º-0-90º-0 readings. The machined aluminum frame is rigid and light with a precise platform that allows the sensor and its microprocessor circuit to provide hight accuracy throughout the entire 360º range.

• Four 90º quadrants for display purposes.
• Calibrates in minutes without any special fixtures.
• HOLD button for freezing a reading in an unreadable position.
• ABS/ZERO button allows 2 measuring modes, Standard and Alternate Reference.
• V-grooves on top and bottom for use on curved surfaces.
• Angle displayed upright regardless of Protractor position.

SPI - Pro 3600 Digital Level - Angle Measurement Tool

• Full 360 degree range (90° x 4).
• Easy to read LCD display.
• Maximum accuracy of +/- 0.05° and maximum resolution of 0.01°
• Precision, machined aluminum frame.
• Unit can be recalibrated to factory accuracy in the field without special tools or fixtures.
• RS-232 compatible interface for computer data collection.

The PRO 3600 Digital Protractor from SmartTool Technologies is a revolutionary measuring tool that provides an immediate, digital reading of all angles in a 360° range. The unit utilizes a patented, liquid-filled sensor combined with precision measurement circuitry to provide unparalleled accuracy and stability.

A precision machined aluminum frame provides a rigid, lightweight, ultra-precise platform for extremely accurate measurements. The frame is grooved along the bottom surface to facilitate use with round objects such as pipes or shafts and incorporates threaded holes on the bottom for rigid attachment if desired.

The front panel buttons can be used to capture desired readings or to designate an alternate reference surface from which subsequent angles are then measured. The unit can also be easily recalibrated in the field to factory accuracy using any available flat surface.

The PRO 3600 features an RS-232 compatible serial interface for transmission of angle measurement data to a computer or other equipment. The unit operates for up to 500 hours on a single 9V battery, incorporates an automatic power down feature, and ships standard with a rigid plastic case.
