[Advantages] The long, thick test needle is oxidation-resistant, durable, and highly accurate. The cap is equipped with a dustproof cover to prevent dust and foreign matter from entering. [Good Quality] The lead is made of soft, high-temperature resistant silicone. It is tension and high-temperature resistant, does not harden in winter, does not harden in antifreeze, is burn-resistant, and has a copper core. It is durable. [4mm Right Angle Plug] The multimeter plug is a standard 4mm right angle plug, suitable for most multimeters. [Specifications] The test lead shaft is approximately 15.5 cm long, and the effective probe is approximately 2 cm. The total length is approximately 110 cm. Weight: 78 g. High and low temperature resistance: 0-40°C. CCAT III 1000V / 20A. Color: Red/Black. Note: 1000V, 20A. Scope of application: Standard instrument with standard 4 mm banana plug. 1000V 20A Gold-Plated Copper Needle Multimeter. Product Name: 20A 1000V Gold-Plated Copper Needle Universal Multimeter with Large Extra-Tip. Product Material: Copper needle, flexible shaft, full sheath, crosshead socket. Ensures efficient connection. Product Specifications: Line length 90 cm, test lead shaft length 15 cm. Effective 2.2 cm probe. High and low temperature resistance: 0°C~40C. CATIII 1000V 20A. 【Application】The multimeter pen is suitable for connecting compatible electrical meters to equipment, testing electrical circuit lines, and is widely used for measuring current, voltage, resistance, continuity, triode, and voltage testing. A good aid for modular home maintenance. Product features: Uses an extra-soft PVC silicone wire, a soft, break-resistant rubber handle, a 10 cm copper probe, and a gold-plated front design. This makes the test pen more sensitive and accurate during testing. Good quality, and the connecting head is durable. It can be directly connected to the wattmeter, and the meter tip is very sharp, which is very suitable for measuring very small IC pins, LED lights, and small components.
