Marmonix MVB 200 Handheld 3-Mode Vibration Meter

The Marmonix MVB 200 vibration meter lets a maintenance technician walk up to a pump, fan or motor, press the probe on the bearing housing and read in a second whether vibration is normal or rising. It measures acceleration, velocity and displacement with a piezoelectric accelerometer and two probes, so one handheld tool covers routine checks on most rotating machines. See all Marmonix vibration meters to compare.

The meter reads acceleration to 199.9 m/s², velocity to 199.9 mm/s RMS and displacement to 1.999 mm p-p, with ±5% ±2 digits accuracy. A LO/HI band switch (10 Hz–1 kHz or 1–15 kHz) helps separate general imbalance or looseness from early bearing damage. It runs on a single 9 V battery and weighs 182 g.

Why maintenance teams choose the MVB 200

• Three modes in one meter: acceleration (peak), velocity (RMS) and displacement (p-p)
• HI band to 15 kHz in acceleration mode for early bearing and gear faults
• Two probes: short probe for HI and LO, long probe to reach narrow points on LO
• Hold on release: the reading stays on the display after you let go of MEAS
• AC signal output to listen with headphones or connect a recorder
• Simple to run: 9 V battery, about 20 h of use, auto-off after 60 s, backlit LCD
• 2-year warranty and local support

Where the MVB 200 is used

• Building services and facilities: chilled water pumps, AHU and cooling tower fans, booster sets
• Manufacturing plants: motors, gearboxes, compressors and conveyors
• Power and utilities: auxiliary pumps, blowers and generator sets
• Metals and heavy industry: rolling mill drives, mixers and crushers
• Commissioning: baseline readings after installation, alignment or a bearing change

Probe guide

How to take a vibration reading

1. Press the power key and select acceleration, velocity or displacement.
2. In acceleration mode, choose LO (10 Hz–1 kHz) or HI (1–15 kHz). Velocity and displacement always use LO.
3. Mark a measuring point on the bearing housing, close to the shaft, and use the same point every time.
4. Hold MEAS and press the probe at right angles to the surface with a steady force of 500 g to 1 kg.
5. Wait for the reading to settle (1 update per second), then release MEAS to hold the value.
6. Record the value, mode and band, and compare it with earlier readings and with the ISO 20816 limits for your machine class.

Safety: keep the meter, cable and loose clothing away from rotating shafts and couplings. Do not clean with solvents, and do not use or store it above 50 °C or 90% RH.

Build a complete machine check

Vibration is one sign of machine health. Add bearing temperature with the MIT-700 infrared thermometer and shaft speed with a tachometer (see our tachometer buyer’s guide). If you need data storage, temperature and a higher range, step up to the MVB 600.

MVB 200 vibration meter FAQ

What does the MVB 200 measure?

Acceleration from 0.1 to 199.9 m/s² (peak), velocity from 0.1 to 199.9 mm/s (RMS) and displacement from 0.001 to 1.999 mm (peak-to-peak), with ±5% ±2 digits accuracy. Choose the mode with the mode key and read the result on the 3½-digit LCD.

When should I use acceleration, velocity or displacement?

Use velocity (mm/s RMS) for overall machine condition, the value most severity standards use. Use acceleration on the HI band (1–15 kHz) for early bearing and gear wear. Use displacement on slow-running machines, where movement matters more than speed.

What is the LO/HI key for?

It switches the acceleration band between 10 Hz–1 kHz (LO) and 1–15 kHz (HI). It only works in acceleration mode. When you change to velocity or displacement, the meter returns to LO automatically.

Which probe should I use?

Use the short probe, already fitted to the meter, for most readings on HI or LO. Use the long probe only to reach narrow spots, and only on LO, because it can resonate above 1 kHz and give false high readings.

How do I get repeatable readings?

Hold the MEAS key and press the probe against the same point on the machine each time with a steady force of 500 g to 1 kg, at right angles to the surface. Release the key to hold the value. Record the mode, band and point so trends are comparable.

Can I listen to the vibration signal?

Yes. The AC output gives 2 V peak at full scale into 10 kΩ or more, so you can connect headphones to listen to bearings or feed a recorder. Start at low volume, because the output can be very loud.

How is the MVB 200 different from the MVB 600?

The MVB 200 is a simple spot-check meter on a 9 V battery. The MVB 600 reads up to 300 m/s² and 850 mm/s, adds temperature, and stores about 397,000 readings in 8 MB of memory for route-based monitoring.
