The Reed R7100 portable contact/noncontact tachometer measures up to 99,999rpm, has a laser beam for noncontact measurements, and a five-digit LCD screen. This contact/noncontact portable tachometer is used for measuring the speed of motors, conveyor belts, and other moving and rotational systems. It measures rotational speed from 10 to 99,999rpm for noncontact measurements, and from 0.5 to 19,999rpm for contact measurements, with + or - 0.05% accuracy. It is autoranging, to display the most appropriate test result value automatically. It measures surface speed from 0.5 to 1,999.9m/min. Its optical sensor is a laser beam that works at a distance from 50 to 500mm for user safety. The LCD screen presents test results and the unit of measurement, and it stores the maximum, minimum, and last test result values for ease of data recall. It comes with a cone contact adapter, a funnel contact adapter, a surface speed wheel, four AA batteries, reflective tape, instructions, and a carrying case. This tachometer is suitable for measuring rotational speed and other measurements in mechanical or industrial engineering environments.Specifications Noncontact range 10 to 99,999rpm Contact range 0.5 to 19,999rpm Surface speed range 0.5 to 1,999.9mpm Accuracy +/-0.05% Resolution 0.1rpm Operating distance 50 to 500mm Power (4) AA batteries Dimensions 210 × 74 × 37mm/6.3 x 2.8 x 1.5 inches (H x W x D) Weight 7.9 oz. H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.Tachometers measure the rate of rotation or surface speed of motors, conveyor belts, and other moving systems. Contact tachometers take measurements through direct contact with the moving surface, and can measure both rpm and surface speed. Typically, contact tachometers come with a range of attachments that can be used to measure speed on different kinds of rotary systems, which may include tips used for measuring shafts with a central hole or flat end surfaces, and rotary wheels for measuring conveyor belts. Noncontact tachometers take measurements from a distance using a beam of infrared light, and provide highly accurate measurements. Contact tachometers are an excellent choice for dirty and dusty environments; noncontact tachometers only calculate rpm but are considered safer because they do not require the operator to be in close contact with the moving surface. Contact/noncontact tachometers, also known as dual, or combination tachometers, can be used to take contact and noncontact measurements. Some tachometers can also take other types of measurements, such as count or frequency, while others can output data to a computer for analysis. Tachometers are used in applications such as automobile maintenance, mechanical engineering, and maintenance of industrial equipment.Reed Instruments manufactures test and measurement equipment such as pressure gauges, electrical testers, temperature and humidity instrumentation, and inspection instruments. The company, founded in 2004, is headquartered in Wilmington, NC.What's in the Box?Reed R7100 photo-contact tachometerCone contact adapterFunnel contact adapterSurface speed wheel(4) AA batteriesCarrying caseInstructions

Its a good quality product & accurate. User friendly as well.Excellent product, fulfilled our expectations.We are using it to measure the speed of conveyor beltsThe tach that I used before was an under $20, no brand, Chinese look alike that I bought a few months ago. It worked once. When I tried to use it again the display would not turn on. Very annoying. You get what you pay for.Reeds Instruments R7100 may look almost like its cheap copy but there are differences. Everything fits nicely, with a solid, heavy feel. It has a QC (quality control) sticker that actually means something. It uses 4 AA batteries - the look alike use 3 AA or some use a 9V. I ran my Sherline lathe and checked the RPM with the remote photo sensor and with the contact cone adapter. There was a negligeable difference at 1000 RPM. The contact method showed a few RPM less than the photo, which I could explain by vibration of the shaft.Bottom line, if you need an instrument you can depend on, spend more money and buy one like this.It works well, I only dislike for my application is to measure rpm of the flywheel of the boat motor that I had to read it upside down .excellent value, quality product!Item was open and appeared to be used, I need it for work so I will follow up and see if it works.Simple to use and worked great out of the box. Used it on a verticle shaft on a fertilizer hydraulic spinner to obtain correct continual RPM.Works very well in both contact and optical mode. Helped me verify my Motors RPM at different frequencies with VFD, right on the money.Hello, I buy that item in 2018 for my new job....Actually the item stay in my toolbox for that period. Now, I try to use the Reed Tachymeter for the first and a rotary plastic tooth inside the removable plastic nose of the tachymeter is broken. This broken part cause interference in mesurement value of the apparel. Is it possible to have that part changed....? The tachymeter is unused...I am a heavy duty mechanic and this has worked for me checking hydraulic and electric motor speeds for both rpm and surface speed. I would say its accurate to within 20 rpm in the under 2000 rpm range
