The Morehouse Small Deadweight Machine (SDM): A Powerful Compact, Precision Calibration Partner

Precision Calibration of Small Force Instruments with the Morehouse Small Deadweight Machine

Calibrating small force instruments correctly is often difficult, often accomplished by physically stacking weights.

Small Deadweight Machine (SDM)At Morehouse, continuous improvement with an attention to detail is our hallmark. We know the drawbacks of makeshift setups, like stacking weights or using homemade jigs. The time-consuming calibration process and the margin for error demand a better solution.

With our extensive experience in precision measurement, we've developed an advanced method that not only enhances accuracy but also simplifies the process. This means you can say goodbye to the tedious and error-prone task of weight manipulation, and instead, experience a calibration process that's efficient and hassle-free.

Today, we're thrilled to unveil our newest breakthrough: the SDM, our most compact deadweight machine yet. This innovation is a testament to our commitment to maintaining unparalleled standards of precision and dependability.

Fully automated and equipped with interchangeable weights, the SDM is a game-changer in metrology. No longer reliant on hard-to-handle mass weight sets that need to be converted to force, the SDM ensures that every calibration is tailored to be better than 0.005 % of applied force.

This implies that the weights represent standard force values, meticulously calibrated to account for variations in material density, air buoyancy, and local gravitational conditions at the specific location of deployment.

With our precision adapters and calibrated hangers, tare weight issues are a thing of the past. The smooth precision of automated processes eliminates and replaces vibrations and fluctuations caused by manual loading. With the included software, one operator can oversee multiple machines, streamlining operations and maximizing efficiency.

However, the SDM's impact extends far beyond our lab's walls. Wherever miniature sensors are used—whether in the pharmaceutical industry, material testing, electronic assembly, surgical tools, or high-tech fiber production—the SDM ensures unparalleled accuracy and reliability.

We can create machines that can go as low as 0.044 lbf (20 gf) and up to 44 lbf (20 kgf) with different weight stacks, ensuring that every calibration meets our customers' unique needs.

At Morehouse Instrument Company, precision is more than just a word –it’s our commitment. Through innovation, dedication, and a relentless pursuit of excellence, we're shaping the future of metrology, one calibration at a time.

Key Advantages of the Small Deadweight Machine
