Ohaus Harvard Trip Balance:

The Ohaus Harvard Trip Balance (1450-SD) offers a two-pan design based on the classic Roberval balance principle. Ohaus Harvard Trip balances feature the additional advantages of magnetic damping, beams with sliding weights and a variety of weighing platforms.
Commonly used for comparative weighing to determine the difference in mass between two objects, rather than their absolute value, these balances come equipped with built-in sliding masses. Harvard Trip balances are known for their accuracy and durability - constructed and precision-engineered for years of maintenance-free laboratory use.

• Highly versatile and rugged
• Two-pan design ideal for comparative weighing
• Built-in sliding masses

Ohaus Harvard Junior Mechanical Balance:

The OHAUS Harvard Junior™ has the power to unleash the young scientist in any student. 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.

Plastic pans and bright colors invite younger students to experiment with early measurement and weighing activities. This balance features two interchangeable bowl-type pans that fit over the standard flat weighing platforms and allow for holding and weighing round objects without rolling off. Its built-in handle and lock provides added protection by eliminating oscillation and preventing unnecessary wear during transporation or storage. The stackable design also helps reduce storage space. Additional features include zero adjust knob and manual damping mechanism. Includes an eight piece metal mass set in plastic case and a comprehensive, teacher-created activity guide with background information, vocabulary terms, and reproducible worksheets.

• Unique OHAUS design offers increased durability and superior accuracy employing a precision engineered metal beam for years of maintenance-free classroom use
• Dual style, interchangeable pans allow for a broader range of objects to be weighed including a flat pan similar to the OHAUS Harvard Trip and a bowl-type pan for use in weighing round objects
• Stackable on either platform to maximize storage space when not in use
• A built-in transportation/storage lock helps to protect the longevity of the Harvard Junior by eliminating oscillation and preventing unnecessary wear when the balance is being delivered to your classroom or while stored during non-use
• Includes a free teacher developed, standards-based activity guide with background information and assessments
