Feature

●【Wide Application】The micron gauge is used to accurately measure small pressure changes in a vacuum, usually used in conjunction with vacuum pumps and refrigerant gauges, allowing you to monitor the vacuum evacuation process in precision cooling systems and heat pumps. The digital vacuum gauge can also read the real-time pressure during the evacuation of the refrigeration system to help you judge the degree of moisture removal and elimination of contaminants such as oil and external gases.
●【Large Display Supports Backlight & ℃/℉ Switching】The 4.2CM×4.8CM high-definition display screen supports LCD backlight, which can display clear data even in dark or weak light conditions. When the digital micron vacuum gauge is turned on, short press the "ON/OFF" button to turn on and off the backlight. “UNITS” button: short press to switch pressure units, long press to switch temperature units.
●【Measures 4 Parameters and Wide Application】This digital tachometer gauge can measure photoelectric speed, light source flicker frequency, contact speed and contact line speed. The digital tachometer rpm meter is widely used in moving and rotating equipment such as electric fans, exhaust fans, conveyor belts, lawn mowers, motors, washing machines, paper machines, automobiles, ships, motorcycles, trucks, airplanes, scooters and tractors.
●【High Precision & Large Measuring Range & Switchable 4 Units】The digital tachometer gauge adopts a high-speed microprocessor chip, which makes it more stable and reliable, and the accuracy reaches ± (0.05% × measured value + 1). Measuring Range: Contact speed is 0.10-1999.9m/min, light source flicker frequency is 0.1-6000.0Hz, photoelectric speed is 9.0-99999RPM, contact speed is 1.0-19999RPM. The handheld tachometer supports switching between 4 units: RPM, Hz, m/min and ft/min.
●【HD Display Supports Backlight】Long press the “unit” key of the digital tachometer gauge to turn on or off the screen backlight. The backlight design of the screen allows the rpm tachometer to read data easily in low-light conditions. The LCD screen will display the measurement reminder symbol, battery power reminder, USB connection prompt, numerical display area, memory mark, unit display area, numerical lock, CONTACT symbol, maximum value, minimum value and PHOTO symbol.
