Need a practical, easy-to-use analytical balance for your chemistry classroom? AND Weighing Galaxy HR-150A analytical laboratory balance offers a compact design and all necessary features for most scientific weighing application requiring 0.1 milligram graduations. Affordable and easy to use with a weighing capacity up to 152 grams you'll be able to perform the weighing requirements for most laboratory weighing applications.

A&D Weighing has imposed MAP (Minimum Advertised Price) on the HR150a and the absolute lowest an Authorized Dealer can post for a price is $1478. Although MAP policy prevents us from advertising below $1478 if you simply click the buy icon your purchase price will be much lower when you add the balance to our shopping cart and shipping is free in the lower 48 states of the USA. Remember, the $1478 is an advertised price, NOT your final price.

Calibration is achieved by external calibration and requires you to purchase either a 100 gram or 50 gram calibration weight. If you prefer motorized internal calibration please review the HR-150AZ.

Selling points of the AND HR-150A scientific balance are truly unique when comparison shopping for your next lab balance. This analytical balance is designed with a removable, shatterproof breeze break with antistatic coating. Other manufacturers of lab balances design their analytical weighing instrument with large bulky glass draftshield that is hard to clean. Many are not removable and if you ever do break the glass do you know the replacement cost for the glass can exceed over $500.

The shatterproof breeze break is the perfect design for challenging weighing applications where contamination is a potential concern. Some pharmaceutical or food research labs that must to comply with either FDA or HACCP regulations that specify no glass. The draft shield is removable you can weigh large diameter items that would not fit in the breeze break. Weighing in glove box can sometimes be easier with the breeze break removed. The A&D design is affordable, reliable and adaptive to your weighing application.

A small footprint design saves you space. The HR-150A footprint measures only 8 x 12 inch. The rotary doors mean that the balance takes up no extra space when the doors are open. We can't understand why some other brand analytical balances are designed to be so big and bulky but I guess maybe they think a bigger piece of equipment can justify an overpriced price of lab equipment. The HR-A is a smart weighing design ideal for tight confines of glove boxes or fume hoods. Free up lab benches space since you'll have no problem setting up 2 HR150A balances back-to-back. Plus the top of the breeze break also pivots open, so access to beakers and flasks is easy.

The HR150A balance features a solid metal base on the A&D Super Hybrid Sensor (SHS) technology which delivers consistent weighing results. day-in and day-out in thousands of laboratories and production facilities worldwide. This high precision weighing instrument even has a port for a below balance weighing hook located on the bottom of the balance. You can learn more about below weighing applications here.

While other manufacturers have only a 1 year or 2 year manufacturer warranty the HR-150A is backed with a 5 year manufacturer warranty. If the other brand balance is so good why is their warranty only 1 year?

To see the entire HR-A & HR-AZ Series of analytical balances offering weighing capacity from 102g - 252g here.

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.

AND Weighing

The A&D HR-A/HR-AZ has a programmable unit conversion function. It multiplies the weight data in grams by an arbitrary coefficient set in the function table and displays the result. The coefficient must be within the range between the minimum (0.000001) and maximum (10000). If the coefficient set is beyond the range, an error is displayed and the balance returns to the coefficient setting mode, prompting to enter an appropriate value. A coefficient of 1 was set at the factory.

The shatterproof anti static breeze break is removable for easy cleaning.

The rugged, shatterproof draftshield with anti-static coating makes the HR-A/AZ safe for challenging applications where contamination is a potential concern especially with pharmaceutical weighing application with FDA requirements or food weighing where HACCP requirements restrict a breeze break made of glass.

Rotary doors mean that the balance takes up no extra space when the doors are open. The HR-A Series analytical lab balances are perfectly at home in the tight confines of glove boxes and fume hoods. Crowded academic lab benches are no problem: set-up 2 balances back-to-back.

Breeze break top pivots left or right to allow easy access to flasks and beakers.
In the video above we demonstrate the Sartorius Entris224-1S analytical balance and how easy calibration is when you purchase the optional calibration mass. The Satorius Entris 4 decimal place balances offer a large draftshield with 3 sliding doors. See the quick settling time as we place calibration weights on the weighing platform. Get a better understanding of what each keypad does and how you can enter into the balance configuration menu to change the factory default setting to better meet your specific weighing requirements. The Sartorius Entris is easy to configure to optimize for your individual weighing application.

Select from 6 Analytical Balances to meet your specific weighing needs.

Learn more about the AND FX-700CT as we demonstrate the balance and show you all the features this precision milligram weighing instrument offers. Basically the FX-700CT (152g x 0.001g) is the same balance as the HR-150a (152g x 0.0001g) but the FX-700CT displays 1/10 the resolution. If you want to learn more about the HR-a Series this video is well worth watching.
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.
