Instruments used for non-destructive measurement of vibration parameters such as acceleration, average quadratic value of speed ( effective value) and deviation. This type of vibro meters are extremely fit to perform bearing, machinery, plants and related components maintenance checks Compact design, user friendly, ideal for in-field measurement Compliant to standard: ISO2954. Acceleration (10Hz - 1Khz / 10HZ - 10Khz) 0.1 ~ 400 m/s2 RMS speed (10Hz - 1Khz) 0.1 ~ 400 mm/s Deviation (10Hz - 1Khz) 0.001 ~ 4.0 mm Power supply 4 x 1.5V AAA (UM4) battery set - Battery level Dimensions 124 x 62 x 30 mm Weight 120 g (battery set not included) Equipment: - Casing - Magnetic base - Piezoelectric pressure transducer - 2 tips Optional accessories: Cable and software - headset - SIT and/or RDT certificate
