Tachometer DT-2234B Lutron is a non contact digital photo tachometer used to measure rotational speed from 5 to 99,999 RPM.
Features :
- Laser light detecting source, long measuring range up to 2 meters, it is useful in the RPM measurement application where the machine would be a risk to the operator or close access is difficult or not possible.
- Wide measuring range from 10 to 100,000 RPM, 0.1 RPM resolution for the measured value <1000 RPM.
- Microprocessor based circuit, crystal time base, high precision with 0.05% accuracy.
- High visible LCD display gives RPM reading exactly with no guessing or errors & saves battery energy.
- Memory with recall function, the last value, max., value, min. value will be stored into the memory automatically.
- The use of durable, long lasting components, including a strong, light weight ABS plastic housing, assures almost maintenance free performance for many years.
