AD-4212C Series
* The EM-DLC is a high precision electromagnetic weighing sensor with an integrated analog-to-digital converter
AD-4212C Series EM-DLC To those who wish to double production efficiency
Just 5 mg after 30 million times!
 EM-DLC* AD-4212C-300 (320 g × 1 mg) completed an endurance test
 of 30 million repeated loadings, which took more than 1 year.
 The final value of span drift was a mere 5 digits, or 5 mg (display value
 of 200.005 g for a standard weight of 200 g), demonstrating that the
 product can maintain its accuracy over a long period of use.
 See how the test was performed here (500Kbps).
