The Ohaus Discovery is the professional's choice for analytical weighing applications!
The NEW Ohaus Discovery series of semi-micro and analytical balances combine unmatched weighing performance with Ohaus' SmarText software, making it extremely reliable and easy to use. The Ohaus Discovery lab scale 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 calibrationensures accurate weighing
The Ohaus Discovery series features four analytical models with capacities up to 310 grams by 0.1 mg with a FineRange model that offers 10 microgram readability. The Ohaus Discovery analytical balance is perfect for university research, pharmaceutical research and drug discovery, and general laboratory weighing applications.
Key Features:
Highest Performance
The Ohaus 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 Software
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
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.

Applications
Statistics
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
The Ohaus Discovery analytical balance provides users with four methods of density determination to choose from depending on their need. They are:
- User can determine density for solids more dense than water
- User can determine density for solids less dense than water
- User can determine density for liquid density (sinker needed, not included)
- 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
Pipette calibration checks the accuracy and precision values of pipettes by weight analysis. The Ohuas Discovery DV215CD 0.01 mg 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 Ohuas Discovery will accept an alternate liuid's density in g/cc at current room temperature as well.
Percent Weighing
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
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
This mode allows the user to check the weight of a sample against preset target parameters such as underweight and overweight.
Animal/Dynamic Weighing
Dynamic weighing can be used when eigher 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
This mode allows the user to sum a series of sample weights that can be greater than the capacity of the balance. Totalization is helpful when adding the masses of several samples together without the need for a calculator.
High Point
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.
Additional Features
Multiple Weighing Units
The Ohaus Discovery analytical balance features multiple weighing units including a user-defined custom unit for use in unique weighing applications.
Environmental Settings
When working in harsh environments, users can adjust Discovery's environmental settings to compensate for vibrations and other disturbances.
Connectivity
Discovery comes with an included RS232 interface and provides full GLP/GMP data output
Up-Front Level Indicator
Discovery has been designed with an up-front level indicator eliminating the need to look behind the balance during the leveling process. A quick glance at the up-front level indicator helps to ensure that the balance is level prior to each use.
 Easy to View Display
Discovery features a 2-line alphanumeric LCD display with a brilliant backlight.
Easy to Clean
Discovery's stainless steel platform and removable wind ring make it extremely easy to clean.
 Weigh Below Hook
Discovery's integral weigh below hook allows density determination or calculating the specific gravity
of samples.
