Audio Impedance Testers are precise measurement instruments that are specially applied in measuring audio impedance. It is applied in many wide application, such as measuring the impedance of loud speaker, a set of sounds system, home theater and commercial audio system. For insulation resistance test, you can change the test voltage among 250V, 500V and 1000V. It can also be used to test ACV, resistance which is less than 200Ω, and test for continuity. You can use it to test transformer, motor, cable, switch, electrical appliance as well as to do insulation resistance test. Features & Benefits:

True measurement of speaker systems actual impedance at 1kHz

Three test ranges (20Ω / 200Ω / 2000Ω) allow testing of home theater and commercial sound systems

Convenient portable battery operation

Low battery indication

Data hold function

Timer function for easier operation. The timer can last about 30 seconds after users press TEST button

Auto power off: after about 15 minutes of not-use

Wide measurement range, high stability and reliability

Test voltage can be changed by the rotary switch

High ability to withstand high load

Digital Ohmmeter has full function protection, anti-high voltage circuit design, Handheld megohmmeter includes carrying case and belt, easy to carry and use
