HQRP Digital Laser Photo Tachometer Non Contact Tach for Measuring Rotating Speed of Machines, Motors, Mechanisms, Model cars, Wheels + HQRP UV Meter
HQRP Non-contact laser photo tachometer DT2234C for the owners of service stations or just people who enjoy doing things themselves. Designed to measure engine speed, or speed of any other rotating mechanisms (shafts, fans, blades of gas or water meters, etc.). It is a great tool to measure the RPM (Rotational Speed) of motors and machine parts. In wood and metal working it can be used to accurately measure the speed of a lathe or milling machine. 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. Display: 5 digits, 18mm LCD displaying Test range: 2.5 to 99999 RPM (r/min) Resolution: - 0.1 RPM (2.5 to 999.9 RPM) - 1 RPM (over 1000 RPM) Accuracy: Â±(0.05% + 1 digit) Sampling time: 0.8 sec. (over 60 RPM) Test range select: automatic; Memory: max. value, min. value, last value; Detecting distance: 50 to 500 mm; Time base: 6MHz crystal oscillator; Circuit: exclusive one-chip of microcomputer LSI circuit; Battery: 3 X 1.5 V AA (UM 3) battery; Power consumption: approx. 40mA (operation); Operation temp : 0 to 50 V (32 to 122Â°F). HQRP UV Meter: This meter shows you the level of UV and helps you protect your eyes and skin from negative sunlight effect. The color of the meter changes from very light purple to dark purple depending on the intensity of the UV lighting. The darker the purple color is, the more intense is the UV lighting.
