1. Tip material: CRV alloy steel2. Measurement range: 70-250V (contact)3. Measuring range: 70-600V (non-contact)4. Through-circuit check: 0-20 megohm5. Polarity test: 3-36VDC6. Voltage test: 50-500HZ7. Battery type: 3 x 1.5V LR41 button batteries8. Size: about 163 x 24 x 4 mm, tip diameter about 4 mmFunctional features:1. Multi-function electricity test pen, bright color lights, strong torque measurement, insulated shell, drop-proof and durable, safe identification, fast and accurate2. Electrician grade dual-use electrical pen, intelligent upgraded motherboard chip, higher security performance, longer life3. Electrical pen/screwdriver two-in-one, insulated and drop-proof, with a strong magnetic tip, voltage sensing, zero fire line identification, line breakpoints to find4. Bright sensitive color lights, security power measurement more eye-catching, fast detection, for a variety of electrical circuits hold down the nut, red and green at the same time light for the fire line only light green for the zero line5. Self-test function, to ensure that nothing is wrong, through the human body circuit, will emit a bright light before using the self-test, whether the pen is in normal use does not light up means that the damage or need to replace the batteries6. Line break detection, rapid detection of line failure, hold down one end of the pen with your hand to detect, the other end of the green light for the line is smooth, not light for the line breaks7. DC power detection, battery polarity discrimination, a hand holding the pen with the tip of the pen to contact the battery positive pole, the other hand touching the negative pole, the light indicates that the power is sufficient, the light does not indicate that the power is insufficient or no electricitySpecification: Package Weight One Package Weight 0.10kgs / 0.23lb One Package Size 18cm * 3cm * 3cm / 7.09inch * 1.18inch * 1.18inch Qty per Carton 300 Carton Weight 31.10kgs / 68.56lb Carton Size 47cm * 38cm * 32cm / 18.5inch * 14.96inch * 12.6inch Loading Container 20GP: 466 cartons * 300 pcs = 139800 pcs40HQ: 1083 cartons * 300 pcs = 324900 pcs
