CLEAR INDICATION: Bright LED illuminates green to indicate tester is operational and flashes red and emits a beeping alert when voltage is detected
BRIGHT FLASHLIGHT: Equipped with a bright flashlight, this tester illuminates the work area, allowing for enhanced visibility. The flashlight can also be used independently of the voltage detection function
DUAL-RANGE DETECTION: Select voltage range of 12-1000V, or 70-1000V for targeted voltage detection
VERSATILE AC VOLTAGE DETECTION: The non-contact tester accurately detects AC voltage from 12 to 1000V in various applications, from cables and circuit breakers to switches and outlets
PRECISE VOLT PEN: The volt pen detects AC voltage from 12 to 1000V, providing visual and audible indicators for quick and reliable voltage detection
66-FOOT LASER DISTANCE METER: The incorporated distance meter accurately measures in meters, inches, and feet with high accuracy, up to 1/16 inch (0.16 cm)
HIGH-VISIBILITY DISPLAY: The reverse contrast display ensures clear visibility in low light conditions, allowing easy reading of voltage and measurement results
NON-CONTACT VOLTAGE DETECTION: Detects 12-1000V AC in cables, cords, circuit breakers, lighting fixtures, switches, outlets, and wires
LCD INDICATES SIGNAL STRENGTH: Bar graph display indicates signal strength with more bars lighting up as voltage increases or as detector moves closer to the source
AUDIBLE ALERT: The audible alert indicator increases/decreases rate corresponding to bar graph
3-COLOR LED TIP: Blue indicates low signal strength, red indicates high signal strength, and green indicates that no voltage is detected
SMART BUY: A complete, high-performance kit that offers convenience and value
COMPLETE OUTLET TESTER TOOL KIT: Includes GFCI Tester (Cat. No. RT210) and Non-Contact Voltage Tester Pen (Cat. No. NCVT1P)
DETECT COMMON WIRING PROBLEMS: Quickly identifies wiring issues in standard and GFCI receptacles
GFCI OUTLET COMPATIBLE: Confirms the proper operation of ground fault protective devices in GFCI outlets
SAFETY FIRST: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency and the percentage value will be larger. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected
NON-CONTACT: With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Test. Handy circuit tester for electricians, homeowners
DUAL RANGE: Detects standard and low voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring etc.; The NCV sensor automatically recognizes the voltage and displays it on the bar graph, and the percentage value can display the voltage signal intensity more intuitively
SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines
