克拉稱3000G/0.1G

BL-01 3000g/0.1g電子稱,使用3粒AAA電池(已配送),深藍色+銀色,七種單位:g/oz/tl/gn/ozt/dwt/ct,backlit LCD display(white)Capacity:20g*0.01g,working temperature:10--30°C,LCD display:5 di display,Size:88mm,Weight:105g,Salver size :34*34*5mm

Pros: It seems to be accurate.
It has nice features:
* supports several units (g/oz/ozt/dwt/ct/tl/gn),
* supports tare (most scales do),
* can count pieces,
* can be calibrated.
It does auto power off after 1 minute.
It can be powered with a 6V DC power supply.

Cons: The plate is a little all.
The screen darkens after a few (too few) seconds (much before auto power off).

Other Thoughts: I use it mostly as a kitchen scale.
My previous kitchen scale had a limited accuracy (1g up to 1kg, 5g up to 3kg). The value read on its screen used to drift quite a lot (making the scale close to useless when accuracy was needed). It did not support pieces counting or calibration. It could not use an external power supply. Its sensitive buttons sometimes were malfunctioning. And as far as I remember, it also was more expensive!
