KH4135 Automatic Digital Low Distortion Measuring Instrument User Guide
Nail Polish is removed by Nail Polish Remover, which is an organic solvent, but it may also include oils, scents and colors. A bottle of liquid remover can be used with a cotton ball or a cotton pad to remove the old polish.
The most common nail polish remover contains acetone which is powerful and effective, but it is not good for the skin and nails. So in our nail polish remover, we use ethyl acetate rather than acetone, that is Non-Acetone Nail Polish Remover. Ethyl acetate is also the solvent used in nail polish. Use the non-acetone nail polish remover to protect your nails, choose Midie Cosmetics!

The KH4135 low-distortion measuring instrument is a new type of fully automatic digital instrument. It is redesigned according to the urgent needs of current scientific research, production, measurement and testing, teaching and national defense users to achieve rapid and accurate measurement. The minimum distortion measurement reaches 0.005%. It is an intelligent instrument with a high performance / price ratio. It is the latest member of the KH41 series all-digital distortion meter family.
The voltage, distortion and frequency of the signal under test are all automatically displayed by LED, and true effective value detection is adopted. Voltage measurement can be fully automatic in the range of input voltage 300mV ~ 300V, frequency 10Hz ~ 550kHz; distortion measurement can be fully automatic in the range of input voltage 50mV ~ 300V, frequency 10Hz ~ 110kHz, distortion 100% ~ 0.01%, minimum Can measure 0.005%. The instrument has the functions of balanced and unbalanced input voltage and distortion measurement, and also has the functions of measuring S / N (signal-to-noise ratio) and SINAD (signal-to-noise ratio). Amplitude display unit can be V, mV, dB, distortion display unit can choose% or dB, S / N, SINAD display unit is dB. The instrument is equipped with 400Hz high-pass, 30kHz and 80kHz low-pass filters for user convenience.
