Ohaus PA84 offers 85 grams weighing capacity and increments in 0.1 milligram divisions. The new Pioneer PA84 replaces the discontinued Ohaus PA64. This analytical balance features a 3.5 inch diameter pan with an RS232 interface. The RS232 allows connection to an Ohaus printer or a computer. Sends Balance ID plus spaces for recording User ID, Project ID, time and date.

The PA84 Pioneer lab balance is designed for basic routine weighing in a variety of laboratory, industrial and education applications with the right combination of performance and features that delivers uncomplicated performance for all your basic weighing needs.

When the Ohaus PA84 balance is first installed, or is moved to another location, the lab balance must be calibrated to ensure accurate weighing results. The Ohaus PA84 requires the purchase of a optional external 50 gram calibration weight to perform calibration. We always recommend that you purchase the calibration weight when you purchase the balance. You can learn more about calibration weights and the tolerances at If you want internal motorized calibration see the Ohaus Pioneer PA84C

Ohaus Pioneer PA84 features weighing, parts counting, percent weighing, animal weighing a density determination weighing functions. An optional density kit is available or use the built-in weigh below hook allowing you to suspend an item below the balance to calculate density/specific gravity.

All models are built on a solid metal diecast base and use a magnetic force restoration weigh sensor, not a cheap strain gauge that is prone to drifting with the numbers on the display moving even though you added nothing to the weighing platform. We get so many calls from end users saying they purchased some no name brand made and they hate their balance since it is a strain gauge. If you don't understand then watch this video HERE demonstrating a magnetic force restoration balance verses strain gauge scale.

The large draftshield features sliding top and side doors. To address the ease of cleaning requirement often expressed by routine users, Pioneer's draftshield has been designed with easy to remove doors and panels. Disassembly takes just seconds and all components including the balance housing can be quickly wiped clean.

Periodic cleaning made easy helps avoid sample contamination and extends product life. In addition, a standard in-use cover provides added protection against accidental spillage and helps minimize the chance of damage to the display and keypad.

Should breakage occur, each replacement door or panel can be installed in seconds. A standard in-use cover provides added protection against accidental spillage.

Pioneer has been designed with an up-front level indicator, so that users can quickly ensure the balance is level prior to use. Selectable environmental settings to help adapt the balance to real life working conditions, Pioneer is designed with selectable environmental settings. When working in harsh environments, the balance can be adjusted to compensate for vibrations and other disturbances. Conversely, the balance can be adjusted for working in slow filling applications where sensitivity is a must.

Be sure to see the Scientech ZSA Series featuring 80 to 210 gram with 0.1mg resolutions. When US government customers call us saying they must comply with the Buy American Act clause the only similar balance we offer to the PA84 that is made in America would be the Scientech ZSA80. FAR Part 25.003 requirements state that domestic end products are preferred over foreign end products, and the Ohaus Pioneer is not made in the USA, but instead China.

See our most technologically advance weighing instrument we offer - 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.

The Ohaus Pioneer Series has been upgraded to the new Ohaus Pioneer Plus Series. The new Pioneer Plus has an expanded selection of 24 different models to choose from. Select an Ohaus lab balance according to your laboratory's specific weighing requirements. You can review all of the Ohaus Pioneer digital balances HERE.

We understand purchasing an 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.

Before purchasing any analytical balance, be sure you review the AND HR-100A designed with a removable, shatterproof breeze break with antistatic coating perfect for challenging weighing applications where contamination is a potential concern. Plus the small 8 x 12 inch footprint design saves you space. Finally, the AND HR-100A offers a 5 year warranty while the Ohaus PA84 is only 2 years.

Ohaus Pioneer laboratory balance weight display
The new Ohaus Pioneer Pro Series features a red overlay keypad display and bright backlit LCD display provides ample lighting, making the display very easy-to-view in laboratories with dim lighting. The predecessor model, Ohaus PA64, had a blue overlay and no backlight display. The spirit bubble is located to the right of the weighing display so you can verify at a quick glance that your balance is level for optimum accuracy. The Ohaus Pioneer Pro Series now features the "Density Determination" weigh function. These great new upgrades we believe will increase the demand even more for this basic entry level analytical balance.
Lab balance with optional scale printer
On the rear of the balance you'll find a built-in RS232 allows connection to an Ohaus SF40A impact printer or a computer. Sends Balance ID plus spaces for recording User ID, Project ID, time and date.

Integral security bracket allows you to secure your balance to a workstation to prevent unwarranted movement or theft

The 2 adjustable rear leveling feet level indicator helps to ensure that the Ohaus balance is level.
Weigh below hook for specific gravity
The Pioneer Pro balance is now equipped with a weigh below hook for weighing below the balance. Before turning the balance over, remove the pan and draft shield elements to prevent damage. The black removable protective cover is the weigh below underhook opening. To use this feature, remove power from the balance, then remove the protective cover for the weigh below opening. The balance can be supported using lab jacks or any other convenient method. Ensure the balance is level and secure. Power on the balance, then use a string or wire to attach items to be weighed. Below weighing is used for weighing magnetic materials, large samples that won't fix on the weighing platform or extremely hot or cold sample that would effect the balance's electronics if placed directly on the weighing platform due to thermal heat/cold transfer. Additional applications would be specific gravity determination.
Ohaus digital scale usb drive for storing weighing data
An OPTIONAL PAD7 Auxiliary Display Kit for Pioneer is available. This secondary display can be useful in science and chemistry classroom setting allowing students to see the weight display without being direct over the balance looking at the display. This second display plugs into the RS-232 port on the rear of the balance.

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.
