What this information worth to us?
For the ones
interested to buy used instruments when actual product label at the back of the instrument this includes CE marking, this translates
to production date 2011 and later. PF9800 series first models these appear at China domestic market somewhere at the year 2000.
The instruments
with out CE marking they are
verified antiquities.
The major issue with all EVERFINE products (digital power meter), this is the tremendously unreasonable pricing.
The problem, this starts from EVERFINE headquarters, and all domestic sellers they inflates even further the pricing.
Nowadays EVERFINE has only two fresher models year 2017, and both is development of some one else.
Therefore beware when shopping for: PF9800/PF9901/PF9805/PF9810/PF9811 (Basic power meter model)
Second beware: PF9810/PF9811 they include basic windows PC software,
always make sure that relative CD media this is included with the meter.
EVERFINE help desk and website, both have the bad habit
to hide documentation and software from public access.
