DT2236B 2 in 1 Contact / Non-contact Tachometer for Laser Photoelectric / Rotational / Surface Speed Test<br /><br />Description:<br />This digital tachometer is a high quality instrument using non-contact (laser / photo) and contact method to measure the rotational speed (RPM) and surface speed with wide measuring range and high resolution. It is featured with high accuracy measurement， quick measuring time and long detecting distance up to 500 mm (20 inch) with Laser.<br />This tachometer is very easy to use by applying a reflective mark (included in package) on target object， then aim at the mark by Laser beam. This tachometer has wide range of applications include measuring rotating speed of machine， motors， model cars， wheels， lathe for metal or wood cutting work etc.<br /><br />Main Features:<br />● Large 5 digits LCD Display<br />● Offers 3 measurement options: Photo / laser， contact and surface speed<br />● Use Microcomputer (LSI circuit) and junction laser technique to combine photo (RPM) and contact tachometer (RPM， m/min) into 1 meter<br />● Wide measuring range (99999 RPM) with high resolution<br />● Memory storage with maximum， minimum and last measured value<br />● Can be connected to 6 V direct current (DC) by using AC transformer for long operation<br />● Low battery power indication<br />● One push button for contact and photo measurement can be switched at anytime<br />● New surface speed sensor with flute veils to measure speed and length of wire， cable and rope conveniently<br /><br />    Specifications<br />General<br />	 Model: DT2236B                                                  <br />                        Material: Plastic                                                  <br />                        Type: Measuring instruments                                                	<br />Classification<br />	 Professional instruments: Analyzer                                                	<br />Specification parameter<br />	 Primary functions: The measurement rotation speed， wire speed                                                  <br />                        Features: Contact type and Laser type 2 in 1                                                  <br />                        Measurement range: Photo Tach: 2.5~99，999RPM; Contact Tach: 0.5~19，999RPM; Surface Speed: 0.05~1，999.9(m/min)                                                  <br />                        Working Mode: Instant Measurement                                                  <br />                        Maximum Show Value: 99，999 RPM                                                  <br />                        Sampling Time: 0.5 second                                                  <br />                        Resolution: Photo Tach: 0.01RPM(2.5~999.99RPM) ，0.1RPM(1，000~9，999.9RPM)， 1RPM(over 10，000RPM) ; Contact Tach: 0.01RPM(0.5~999.99RPM) ， 0.1RPM(1，000~9，999.9RPM) ， 1RPM(over 10，000RPM) ; Surface Speed: 0.01m/min(0.05~99.99m/min)，                                                  <br />                        Accuracy: ±(0.05%+1 digit)                                                  <br />                        Working Temperature: 0 to 50 C                                                  <br />                        Working Power: 1.5V AAA battery 3PCS                                                  <br />                        Scope of application: Industrial， Agricultural， Education， Home appliance， Office                                                	<br />Weight and Size<br />	 Product Weight: 0.185 kg                                                  <br />                        Package Weight: 0.617 kg                                                  <br />                        Product Size: 18 x 8 x 3 cm / 7.07 x 3.14 x 1.18 inches                                                  <br />                        Package Size: 26 x 13.5 x 7.5 cm / 10.22 x 5.31 x 2.95 inches                                                	<br />Package Contents<br />	 Package Contents: 1 x DT2236B 2 in 1 Contact / Non-contact Tachometer， 4 x Speed Measurement Fitting， 3 x Reflection Tape， 1 x English Manual， 3 x 1.5V AAA Battery                                                	<br /><br /><br /><br />                                            <br /><br />                                                <br />
