35*44*4.5 in centimeter, this is the exact dimension of BTS9000-5V5A-2CH! Small as a laptop(you can tell from the left side picture), but it also has the best performance: 1000Hz data record frequency, 0.02% accuracy, 4 auto-switch output ranges, 400us minimum pulse width, etc.
Usually we won’t suggest this model to customers, but if you need to carry the tester around everywhere(such as for a demonstration or work in site), then BTS9000-5V5A-2CH would be the best choice.
