Radius gauge Phi Boy

Now measurement of every Radius and Contour is possible Phi-Boy is a revolutionary and easy to use digital gauge for both ID and OD as well as columnar, cylindrical, conical, and spherical shapes. Phi Boy Features 3D shape ID / OD easy measurement and digital displaying 1. Operability - Automatic readout mode*1 enables an easy and quick onsite measurement. 2. Economy - Measurement of both inner and outer radii is accomplished with one unit. Measurement of both small and large work pieces is accomplished by just changing attachments. 3. Accuracy - Within +/- 0.01mm (lower accuracy for larger objects) 4. Partial Measurement - No need to measure the entire work surface. 5. Measurement Range - 20mm to 10,000mm (10 meters) 6. Alarm*2 - Warning buzzer goes off and lamp comes on when the reading exceeds the preset minimum / maximum. 7. Calculation - Calculates and indicates both radius and diameter, average value, and standard deviation. 8. Recordability - Storage of up to 5 readings. Printouts the individual readings, average, the size of base attachment (L and R) and data. 9. Gradual R Measurement*3 - Measures continually varying radius using a base attachment with spherical contact legs. 10. Waviness - Measures waviness and gyration on flats, columns, and spheres. *1. Automatically accepts a "h" value (or max. peak or min. valley) when the extended line from the measuring tip to the center. *2. Applicable for detecting machining errors, routine radius check and go / no-go decision making for mass-production items. *3. Indicate the true radius, which goes through the two legs of the base attachment, indicator contact tip in contact with work piece.
