MITECH portable vibration meter MV800C is made up of piezoelectric transducer and digital display
circuit. It is mainly used to measure vibration acceleration, speed and displacement of various rotary
machine. This product has the advantages of large measurement, wide variety, intuitively demonstration,
small size, light weight etc. It is widely used in measurement on site or at height and can reduce the
working strength, improve the working efficiency.

1.1 Application

MV800 is mainly used in monitoring the vibration of machines, such as industries of manufacturing,
electric, metallurgy, vehicle etc, specific on the quick check and preventive check of bearing, gear, motor,
fan lathe etc.

1.2 Features

judge the running state of device.

1.3 Technical Parameters

Vibration pickup: Integrated ring acceleration transducer
Measurement range(displacement): 0.001~1.999mm(Peak to peak: valid value*2√2)
Measurement range(speed): 0.1~19939mm/s (valid value)
Measurement range(acceleration): 0.1~199.9m/s2(peak value: valid value*√2)
Measurement accuracy: ±5% measured value

Indication error: ±2

Frequency range: 10Hz~10KHz
Display mode: 3-digit Semi liquid crystal display

Sampling period: 1s
Output signal: AC 2v(peak value, full measurement above 10k)
Dimensions: 185mm*68mm*30mm
Power model: 6F22 9v packed cells
Battery life: continuous use for 30 hours

1.4 Working Principle

MV800C combines the quartz crystal and PZT piezoelectric effect together. When the quartz crystal or
PZT is under strength, the surface generates charger, the vibration was changed into electrical signal by
acceleration transducer. After processing and analyzing, the acceleration, speed and displacement are
shown out in the liquid screen.

1.5 Working Conditions

Operation temperature: 0~50℃
Memory temperature: -30℃~+70℃
Relative humidity: below 90%RH
