Description
HIGH PERFORMANCE: 4-digits display, clear and easy for readings. Mini size, high performance, and fast reaction speed. The digital LED tachometer size is about 80*25*40mm(L*W*H). Two LED colors for red/blue..HIGH STABILITY: With good stability, and anti-interference ability. Over-range display, the thousand unit display "1" or "-1", the last three do not show. The Voltage is DC8-24V, Current is 30mA..HIGH ACCURACY: using the latest A/D conversion chip, high stability reference IC and stick chip components. The measurement range is 10-9999rpm, and the accuracy is up to 0.1％. Clear zero time is About 10s..SETTABLE PARAMETERS: Setting parameters will be memorized when power is off. Suitable for detecting the speed of every kind of motor. Display refresh rate is more than 3 times/sec..EXTENSIVE APPLICATIONS: The digital LED tachometer can be applied to voltage and current measurement, and also can be an external sensor to measure temperature, pressure, displacement, and other physical quantities.
