Checkweigher system

As retailers continue to implement new quality standards, small to medium size businesses must adapt in order continue supplying a highly accurate and reliable product. Retailers have many benefits of doing business with smaller local packers. Some benefits include locally grown products, unique branding opportunities, and more control over the end product. While this is great for manufactures and food processors it can also present several issues such as ensuring production speeds and maintaining accuracy requirements.

This is where checkweigher systems come into play. Implementing in line checkweighing ensures product is not being given away while also not allowing under weight products to make it to retailers or consumers. Fortunately A&D has a solution to this problem, our high speed and highly reliable EZI-Check Checkweigher system. We supply checkweigher system / checkweigher machine in Egypt, Middle-east and Africa.

Reasons for introducing checkweighing solutions for your production line:

Reason 1 Avoiding costly fines and order rejects Reason 4 Product filling machine feedback
Reason 2 100% product inspection Reason 5 Avoid additional labor costs & reduce false rejects
Reason 4 Produce more packages with materials saved Reason 6 Improve efficiency in your process



Two kilogram capacity checkweigher with resolution to .01g speed up to 320 ppm. Flipper-or drop-type rejector available.


Six kilogram capacity checkweigher with resolution to .1g, speed up to 145 ppm. Pusher-type rejector available.


600 gram capacity checkweigher with throughput up to 400 pieces per minute. Airjet rejector available.


Unique modular design

AD-4961 consists of four units: an infeed conveyor unit,
a weighing conveyor unit, a control unit and a base unit, allowing fast and simple assembly.

Image import from USB

Product images can be quickly uploaded to the checkweigher from a USB flash drive, making product identification and upload fast and simple.

Best-in-class precision

With a newly developed digital load cell and an ultra-high speed processing module, high level precision of 0.08 g been realized.

Lightweight and compact design

With it’s modular structure, the AD-4961 allows for rapid and simple installation or relocation.

7 inch color touch panel

The display utilizes a high visibility touch panel color LCD with friendly Graphic User Interface (audio guidance support function included).

Optimization of weighing configuration

By inputting throughput (products per minute) or belt speed (m.min), optimal weighing conditions can be automatically set.

Stores up to 1000 products

Products can be divided into 10 different groups with up to 100 products able to be recorded within each group.
