The Professional’s Choice For Analytical Applications!

The OHAUS Discovery series of semi-micro and analytical balances combine unmatched weighing performance with OHAUS’ innovative SmarText™ software, making it extremely reliable and easy-to-use. The Discovery features durable glass and steel construction and together with advanced AutoCal internal calibration make it the best performing balance in its class:

• Highest Performance with repeatability and linearity performance that’s 2x better than most balances in its class
• SmarText™ Software utilizes text prompts to guide users through application use and balance setup
• Advanced AutoCal™ automatic internal calibration ensures accurate weighing

The OHAUS Discovery series features four analytical models with capacities up to 310g by 0.1mg with a FineRange™ model that offers 10 microgram readability. Discovery is perfect for university research, pharmaceutical research and drug discovery, and general lab applications.

Highest Performance

Discovery’s repeatability and linearity performance is 2x better than most semi-micro balances in its class. Glass and steel construction resists the effects of static and corrosion increasing balance stability and accuracy, as well as extending product life.

SmarText TM  Software Brings Man and Machine Together

SmarText™ is OHAUS’ easy to use balance software that utilizes text prompts to guide users through
application use and balance setup. Delivered through a 2-line backlit LCD and clearly marked
buttons, SmarText™ tells you what is going on and what you have to do next.

Utilizing the 2-line LCD, SmarText™ simultaneously displays weight and application-specific information such as percent or count. At the touch of the Function button, SmarText™ will display application reference information such as the average piece weight (APW).

Advanced AutoCal™ Automatic Internal Calibration

To minimize weighing errors and ensure accurate measurements, AutoCal™ utilizes two internal weights to perform a linear calibration.

AutoCal™ internal calibration system automatically calibrates the balance when it senses a temperature change significant enough to affect the weighing accuracy.

OHAUS Discovery Application Modes:

Statistics Mode

Statistics are used when it is desired to compare a number of samples and examine the relative deviation of the samples along with other statistical data. A minimum of three samples are required in this program. Statistics contains menu options which include: number of samples, maximum, minimum, difference, sum, mean, standard deviation, relative deviation, auto sample, and auto print.

In addition to standard weighing, statistical data can be provided for Animal/Dynamic Weighing and Checkweighing measurements.

Density Mode

Discovery provides users with four methods of density determination to choose from depending on their need. They are:

1.  User can determine density for solids more dense than water
2.  User can determine density for solids less dense than water
3.  User can determine density for liquid density (sinker needed – not included)
4.  User can determine density for Porous material (impregnated with oil).

After entering a couple of parameters into the balance, the built in density table, and mass measurement of the balance take over to provide rapid and accurate density results, with no manual calculations needed.

Pipette Calibration Mode

Pipette calibration checks the accuracy and precision values of pipettes by weight analysis. The Discovery DV215CD 0.01mg semi-micro balance is recommended for maximum accuracy. To calibrate a pipette, the user will select the type of liquid to be used in the pipette (normally water), barometric pressure, nominal value, and unit of measure of the pipette. The balance will do the rest.  The Discovery will accept an alternate liquid’s density in g/cc at current room temperature as well.

Percent Weighing Mode:

This mode allows the user to display the weight of a sample as a percentage of a reference weight useful in sieving applications, reagent weighing, moisture determination, and other types of ingredient mixing.

Parts Counting Mode

Parts counting mode is useful when counting pills, or parts that have a consistent, but low nominal mass. This mode allows the user to count based on a calculated piece weight. The optimization feature improves counting accuracy by automatically re-calculating the piece weight as parts are added.

Check Weighing Mode

This mode allows the user to check the weight of a sample against preset target parameters such as underweight and overweight.

Animal/Dynamic Weighing Mode

Dynamic weighing can be used when either a rough environment is encountered such as on a ship, or when in a location that may not have ideal conditions. In addition, this mode allows the user to weigh moving objects such as animals, insects or other moving specimens. Dynamic weighing averages out weight readings over a period of time and displays the results until cleared.

Totalization Mode

High Point can be used when analyzing batches or lots, or for quality checking of random samples. When in High Point mode, the balance will save only the highest weight value from a series of weighings.
