Product Overview

The MB120 offers a measurement range of 0 to 120 g with a linearity of ±0.02 % of full scale and repeatability of ±0.001 g, meeting the stringent requirements of quantitative analysis. Temperature compensation is built‑in, allowing the balance to maintain accuracy across a typical laboratory temperature range of 15 °C to 30 °C. Power is supplied by a universal 100‑240 V AC adapter, eliminating the need for batteries and ensuring stable operation during long testing sessions. The high‑contrast LCD provides clear numeric readout and includes indicator icons for tare, zero, and calibration status, enabling quick visual verification of the instrument’s condition. Although the MB120 does not include built‑in data communication ports, its external interface can be expanded with optional Ohaus accessories for serial or USB connectivity, facilitating seamless integration with laboratory information management systems (LIMS).

Designed with user ergonomics in mind, the balance features a removable draft shield that protects the weighing chamber from air currents, dust, and static discharge, which can otherwise affect measurement stability. The internal weighing platform is made from corrosion‑resistant stainless steel, providing a smooth surface that is easy to clean with mild solvents. Controls are positioned on the front panel for intuitive access, and the tactile buttons offer a satisfying response while minimizing the risk of accidental activation. The compact footprint also includes a built‑in storage compartment for small accessories such as weighing boats or sample containers, keeping the work area organized and reducing the chance of misplaced items during routine laboratory procedures.

Ohaus ensures that the MB120 complies with international standards, including OIML Class F certification and ISO 9001 quality‑management system accreditation. The balance is shipped with a two‑year limited warranty covering manufacturing defects and includes a calibration certificate that validates its performance out of the box. Users receive a comprehensive user manual that details operation, maintenance, and troubleshooting procedures, as well as access to Ohaus’s online knowledge base where additional resources such as video tutorials and FAQs are available. This combination of certification, warranty, and support documentation provides confidence that the instrument will deliver reliable results throughout its service life.

Usage

Typical moisture determination workflows begin with the placement of a clean, pre‑weighed container on the balance pan, followed by the addition of the sample material. After the sample is introduced, the balance automatically stabilizes and displays the net weight, allowing the operator to record the initial mass. The sample is then subjected to drying, either in an oven or using a desiccator, and the weighing process is repeated at defined intervals until a constant weight is achieved. This gravimetric method, supported by the MB120’s high resolution, provides precise moisture content calculations essential for compliance with pharmacopeial standards such as USP  and EP .

For laboratories that require data logging and integration with software platforms, the MB120 can be paired with optional Ohaus communication modules that enable USB or RS‑232 serial output. This connectivity allows measurement data to be captured directly into spreadsheet applications, statistical analysis tools, or LIMS environments, reducing manual transcription errors and improving traceability. The exported data includes timestamp, weight value, and status flags, which are valuable for audit trails and regulatory reporting. Additionally, the balance’s simple command set ensures compatibility with a wide range of third‑party software, making it a flexible choice for both small research groups and larger quality‑control departments.

Training new personnel on the MB120 is straightforward thanks to its clear display and minimal button layout. The balance’s on‑screen prompts guide users through tare, zero, and calibration steps, while the included quick‑start guide outlines the essential procedures for moisture analysis. Because the instrument does not rely on complex menu navigation, users can become proficient after a brief hands‑on session, freeing up time for actual sample testing. Ohaus also offers optional on‑site training programs and webinars that cover best practices for moisture determination, calibration verification, and routine maintenance, ensuring that laboratory staff maintain high competency levels.
