Ohaus EX125D Explorer Semi-Micro Dual Range Analytical Balance The OHAUS EX125D Explorer semi-micro  (more)balance has been designed with the technology to ensure that your very specific weighing results are accurate. Sophisticated laboratories requiring accuracy and looking for innovative technology to obtain measurement results can find both in Explorer semi-micro balances. It has a max dual weight capacity of up to 52 g/120 grams, and a dual readability of 0.01mg/0.1mg. Internal Calibration OHAUS' signature AutoCal internal calibration system provides routine maintenance by automatically calibrating the balance every time it senses a temperature change of 1.5°C or every 3 hours, whichever occurs first. This helps ensure the accuracy of the balance when the operator has not performed a manual calibration or when the proper calibration masses are unavailable. In addition, to minimize weighing errors and ensure accurate measurements, AutoCal utilizes two internal weights to perform a linear calibration. Intuitive Software Provides an Extremely Modern User Experience The EX125D includes many facets of modern technology to provide the best weighing experience possible. The icon-based navigation provides tactile feedback and operates in the same manner as a smart phone or tablet computer.
