Here in the USA is the same way. When I was a mechanic I had to have tools for both SAE & Metric. I prefer the Metric system.

And some have the cathode marked with a line and some have a negative sign. You have to be careful with Tantalum caps and do a little research. If anyone is not sure what type they have then Wikipedia would be a good place to start investigating.

These type of equipment are mainly use in the oil and gas industries in our country. but most factories who has pipe lines and storage tank will also use this equipment to measure the wall thickness to ensure it meet a particular standard. It is a requirement by national standards.

Albert, in our country we use inches as well as mm. Its a preference of the customer requirements at the time. I have both inches and millimeter block for calibration.

Wilson, the reason I use an Electrolytic Cap instead of the tantalum is just because I did not have a Tantalum at the moment and the customer was very eager to get back the equipment for a job he had. I have since ordered the tantalums and the next available time in comes back in for calibration I will replace the Electrolytic with the tantalum.

MJais, yes these meter are quite expensive and even shipping it back the manufacturer is also quite expensive.
