The MUYA GT633B is a handheld vibration meter for checking machinery health, measuring acceleration, velocity, and displacement on rotating equipment like motors, pumps, and fans. It reads across a wide acceleration range (roughly 0.1-199.9 m/s2) and velocity range (0.1-199.9 mm/s), and its color display can plot vibration curves in addition to numeric readouts. Built-in data storage lets technicians log multiple readings for trend tracking during routine maintenance rounds.
