XJ4630 slow scan two track oscilloscopeDetailed product description：

The XJ4630 oscilloscope has a bandwidth of 1MHz, a maximum sensitivity of 2mV/div, a slowest scanning time of 20s/div, and a slowest scanning time of 500S throughout the entire process. It uses an internally calibrated long afterglow CRT.

The XJ4630 slow scan two track oscilloscope is suitable for observing and measuring low-frequency slowly varying electrical parameters. This instrument can also work in a "single" state, making it easy to observe non repetitive single signal.
