<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><p>Features:<br/>1.Using insulation material: The insulated rubber handle ensures safe and reliable electrical testing, and the high hardness material is drop resistant and durable.<br/>2.Lcd backlit display screen: The backlight is turned on immediately upon startup, and the screen values can be clearly seen even in dark environments.<br/>3.Ncv voltage detection: Press the touch button with your finger. When the induced electric field is weak, the screen will have a green backlight. When the induced electric field is strong, the screen will have a red backlight and emit a buzzing alarm sound.<br/>4.Live neutral wire recognition: In ac voltage mode, touch the instrument pen to the circuit. The live wire: Red screen with buzzing sound, and the neutral wire: Green screen without buzzing sound.<br/>5.Wide range of applications: Zero live wire recognition, self checking function, electrical on-off detection, line breakpoint detection, nvc voltage induction detection.</p><p> Parameters: <br/>Product name: intelligent digital measuring pen<br/>Ac voltage range: non contact measurement: Ac30v-1000v contact measurement: 11v-450v<br/>Product model: b19<br/>Product material: tpe+chrome vanadium steel with magnetic screwdriver head<br/>Frequency: 50-60hz<br/>Probe: optional phillips/phillips screwdriver<br/>Battery: 1*aaa (batteries not included in shipment)<br/>Alarm method: Screen backlight color change+buzzer alarm<br/>Zero line distinction: √<br/>Ncv voltage induction: √<br/>Lcd backlight on screen: √<br/>Electrical on-off detection: √<br/>Energy saving automatic shutdown: The electric pen will automatically shut down after 3 minutes without any operation after being turned on.<br/>Battery undervoltage indication: When the pen is in use and lo is displayed on the screen, it indicates that the battery level is insufficient to drive the pen to work, and the battery needs to be replaced at this time.</p><p>Package include:<br/>Test pen*1<br/>Instruction manual*1<br/><br/></p></div></div><br/>
