Ohaus Harvard Junior Mechanical Balance, 2000g x 0.5g, Single Beam, Plastic Plates

Unlike any balance you’ve ever seen in an elementary classroom, the new OHAUS Harvard Junior has the power to unleash the young scientist pent up in all your students.

Dual style, interchangeable pans which allow for a broader range of objects to be weighed

Stackability on either platform to maximize storage space when not in use

A spring-loaded zero adjust knob & zero adjust compensation beam for precise measurements

Manual damping device to speed up the weighing process

Removable bowl-type or flat pans allow weighing of a variety of materials

Metal beam provides years of maintenance free classroom use

Built-in storage lock protects the weighing mechanism

Built-in carrying handle

Manual damping device speeds up weighing time

A unique design offering increased durability and superior accuracy by employing a precision engineered metal beam for years of maintenance free classroom use. With its unique design, the Harvard Junior offers the combination of a colorful and inviting plastic two-pan balance with the durability and accuracy of the more expensive Harvard Trip, by incorporating a precision-engineered metal beam and zero adjust compensator. The Harvard Junior is not only the most feature-rich balance in its class, but it includes a free teacher-developed, classroom tested elementary activity guide focused on practical, yet enjoyable activities that link science and math concepts, are standards-based, and utilize common items already found in your classroom or at home.The laboratory balance has come a long way from the standardized polished pebbles used in 2400 BC to measure the weight of goods. It is now a common tool used by industries to provide solid, accurate performance and durability for long-term reliability. You can find a laboratory balance in a variety of categories. There’s a sturdy laboratory balance which is great for teaching. You can also pick one that focuses on precision. And there’s even a laboratory balance for use outside the laboratory. Cole-Parmer has a list of balances to choose from. You can select from Ohaus Cent-O-Gram and Dial-O-Gram. These products provide accuracy and the convenience of an integrated weigh-below balance while allowing students to visualize mass measurement principles. They are also designed with a hanging pan system. There’s also the Denver Summit Analytical which features a backlight display and is known for its precision. There are literally thousands choices but Cole-Parmer also offers an easy-to-use guide to pick the laboratory balance perfect for your needs.

What's Included:
8 piece mass set
