DM55-1Digital AC Voltmeter AC 80-300V LCD Volt Meter Socket Voltage Tester Meter Header 110V 220V EU&US Plug Wall Flat 40% off      Description:   Plug type digital voltmeter (electric pen type voltmeter) is widely used in the detection of AC 80-199V-300V mains power (real-time monitoring of the current grid voltage),   Plug the voltmeter directly into the plug-in board or into the wall switch to immediately display the current voltage (whether it is home, office, industrial, mining, etc.)   The biggest advantage is that when you see that the current grid voltage is too low or too high, you can selectively turn off the operation of a certain household appliance or device (especially low voltage is easy to burn household appliances / such as air conditioners, refrigerators, etc.), thereby Effectively protect the service life of your household appliances and equipment (it can also be used as a simple electric test pen).   This meter is only suitable for pure AC 50-60HZ mains power supply. It cannot be used for square wave, inverter output and sine wave circuit measurement, otherwise the meter will be permanently damaged      Features:   1. Wide measuring range: This measuring voltage range of plug-in voltage monitor is AC 80-300V(110V, 220V), low consumption.   2. Flat plug: Designed as a flat plug, plug-in design, this volt tester can immediately detect and measure the current voltage by connecting to the switch plug or wall socket.   3. Function: It helps to check on power health of devices for preventing the low voltage damage to your household appliances.   4. LCD display: LCD digital display with blue backlight, clear and convenient for you to view the data even in a dark room.   5. Applications: Widely apply to measuring the AC voltage in family, office, industrial etc.   6. Good quality: Constructed from good quality ABS material, impact resistant, eco-friendly and flame resistant.   7. Easy to carry: Mini size and light weight, portable to transport and store.      Specifications:   AC80-300V【220V voltage use】   AC80-199V【110V voltage use】   Measuring range: AC80-300V   Output voltage: 110-220V   Input voltage: 110-220V   Environment temperature: 0-50℃   Product weight: 42g   Product specifications: EU PLUG; US PLUG   Number of Digits: 3 Digits   LCD size: 3.6 * 1.8cm / 1.4 * 0.8in   LCD Display Color: Blue   Material: ABS   Measuring Accuracy: ±1.5%, ±2 digit   Color: White   Consume Power: <1W (about every 1200hours consume 1 kilowatt-hour)
