We have NO remaining stock on the AND HR-120 since production was discontinued in 2018. All information displayed herein is for archival and support purposes only. All information displayed herein is for archival purposes only to assist people that might already own this analytical balance. We do not have any remaining parts or accessories left for the AND HR120.

The new replacement model for the A&D HR-120 is the A&D GF-124A. Some of the alternative models to consider would be the AND HR150A, A&D GX-124A, A&D GX-124AE or Sartorius Entris II BCE124-1S.

Private industry, contract manufacturers, college professors, graduate research student - do we have a top quality analytical balance that won't break your budget. Plus the balance is not made in some third world country like China, but instead the A&D HR120 is made in Japan. Be careful and always ask questions before you buy your next analytical balance since you might be surprised how balance manufacturers you "always thought" made their balances in the USA or Europe now outsource the production to China.

A&D is a technology driven, market oriented, global manufacturer of measurement equipment; sensitive to multi-national needs, and always providing ...Clearly a Better Value.

Forget all those games other manufacturer's offer with their over inflated list prices and then they offer you a free accessory or some rewards points that only results in you spending more and more money. Our philosophy is simple - you have a weighing application and you want a quality balance at a great price and Precision Weighing Balances can fill the requirement with the HR-120 sold directly to anyone with access to the internet.

Some of the European Balance manufacturers overcharge you for their balance and then to top it off they "lock out" the ability to perform an external calibration unless you call their service tech. Not A&D, they know if you're smart enough to purchase a high quality lab balance and save $1000's over the european brands then you can simple press "one button" and place the optional calibration mass on the platform to perform your own calibration. The HR-120 analytical balance offers an exceptional combination of remarkable features at affordable prices. 120 gram capacity weigh capacity with 0.1mg readability, 13 weighing functions, percentage and counting modes also! Read all the specifications in detail and even download the HR-Series instruction manual to help you with your buying decision.

When the HR-120 analytical balance is first installed, and when it is moved to another location, it must be calibrated to ensure accurate weighing results. We offer a full line of calibration weights including the recommended 100 gram calibration weight for the HR120.

The A&D HR-Series features: 10 selectable weighing modes, counting, percentage function, zero point calibration, and underhook capability for density measurement & magnetic material weighing.

Before you make your final selection be sure to see the Scientech ZSA Series featuring 80 to 210 gram with 0.1mg resolutions. When US government customers call us saying the must comply with the Buy American Act clause the only similar balance we offer to the HR120 that is made in America would be the Scientech ZSA120. FAR Part 25.003 requirements state that domestic end products are preferred over foreign end products, while the A&D HR120 is made in Japan.

Also review the new AND HR-100A designed with a removable, shatterproof breeze break with anti static coating perfect for challenging weighing applications where contamination is a potential concern. In addition the HR-100A and HR-100AZ come standard with the RS-232 interface while the HR-120 requires you to purchase the optional HR-03 serial interface module if you wanted to connect the HR120 to an AND printer or computer. Plus the HR-100A or the internal motorized version which is the HR-100AZ will cost you less than the HR120.

Finally if you are looking for a balance that comes standard with a USB interface then you must see the Sartorius Secura. Secura offers a simple touch screen technology with easy to read and understand I-cons. The Sartorius Secura124-1S allows you to enable SQmin and additional safety weighing features like the ability to program the minimum weight value so when you attempt to weigh samples below a set threshold the weight reading is displayed on screen in red. Built-in level verification, Password Protection, and memory tracking is also available. Secura is one of the worlds most technologically advance weighing instrument we offer.

We understand purchasing a laboratory analytical balance is a major capital expense and if you have any questions give us a call and one of our weighing experts can discuss your weighing application and get you the most affordable balance for your weighing needs.

Need more accuracy? Do you need a 5 decimal place gram balance? The Sartorius Secura and Quintix semi microbalances are amazing. In the YouTube video above you will see the Sartorius Secura225D-1S semi microbalance [0-120g x 0.01mg] [120-220g x 0.1mg]. We highlight the intuitive operation using the SmartTouch user interface that is so easy to use you'll probably never need to reference the user manual. We also demonstrate the ergonomic draftshield and show how easy it is to dismantle the balance for easy cleaning.

Also you'll get a close up view of the new "collection container". The collection container is designed to keep the spill from entering the lab balance that could cause potential damage to the balance. Sartorius' revolutionary "collection container" features a rimmed design to keep the spill from entering if you happen to spill any liquid or granular samples while weighing.

If the Secura225D-1S is more balance than you need for your weighing application then be sure to see the Secura 125-1S, Sartorius Quintix125D-1S or Sartorius Quintix65-1S. Sartorius is our #1 selling laboratory weighing balances since they are the leaders in building high quality weighing instruments.
