LZ-30,45,60 handheld centrifugal tachometerDetailed product description：

According to different speed measurement ranges, this handheld centrifugal tachometer has three specifications: LZ-30, LZ-45, and LZ-60, mainly used to measure the speed and linear velocity of various machinery and equipment.
Main technical indicators
Usage conditions: The tachometer works normally within the ambient temperature range of -20 to 45 ℃.
Basic error: The tachometer has a basic error of ± 1% of the upper measurement limit in an environment with a temperature of 20 ± 2 ℃
Temperature effect: When the temperature changes from 20 ± 2 ℃ to -20~45 ℃, the additional temperature error of the tachometer does not exceed the absolute value of the basic error limit.
