**FEATURES:**

![](https://smartelectronic.tech/images/oscillo/features.png "")

Compared with the original DSO138, the size is smaller and the function is stronger. 

One piece of calibration function has been upgraded, the test parameters have been improved, and the interface can directly update the firmware.

Originally, DSO138 can test up to 400VPP with 10 times probe, and cannot directly test 220V mains voltage
The new version of 138pro can test 800VPP at 10 times the probe, which is equivalent to AC **280V**. 

The high-end version can directly measure the mains at 10 times the gear, which is more convenient for maintenance.

This one has an embedded rechargeable battery and can be used after charging.
