I did some research on popular cheap testers and scopes present in China.
Data at disposal are collected from the largest online shopping platform taobao.com by searching top sellers+the most popular deals.
1 Clamp meter: 11107 items online.
Top ten best deals are from $4 to $20.
Top3 are respectively $4, $20, and $5 each.
2 DMM Digital Multimeters : 84393 items.
Top ten deals are from $10 to $30.
Top3 cost $6 (nearly 1,000 piece sold every month), $10 (nearly 379p/month), $4. (311p/month).
And the Fluke 17B around $85 are also popular, sold 100 pieces per month.
3 Oscilloscope: 23969 items.
Popular ones are all around $300.
Best seller number 1 ADS1102cal with 100MHz and 1G sample rate sold nearly 60 pieces every single month by one seller
These data are only from one online shopping platform in China among numerous market places in this billion-population country.
Actually the bigger scale of sales are mostly off line in China.
According to one of the top online forums in China ourdev.com, a place where more than 170,927 topics with2,130,682 technical-only replies shared by 41,344,468 visitors, (among them 335,088 regular registered and strictly screened by a standard of at least 5 technical replies after registration，and always around 5000 netters active online) lots of tester&scope users, most as technicians and engineers working for state-owned enterprises in China, use cheap testers and scopes off work and those first class ones are only purchased with reimbursement and fund from government.
And lots of them argued, in terms of usage, in most cases cheap testers work really well and sometimes even better. (esp. considering diode or transistor hFE etc.) I was thrilled to find these cheap scopes and testers on sites likestoreinfinity.com as well as some other distributers of scopes like ADS1102cal or fluke 17b on ebay, which considerably saved my budget on these equipments. For most of us who are not rocket scientists, cheap testers and scopes are really helping for daily circuit debugs and appliance repairs so that we can save money on something more challenging in our lives.
