The Ohaus Explorer semi-micro 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. 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 explorer 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. The  Explorer semi-micro balance has been designed and constructed to provide a modern weighing experience as well as to bolster accuracy.
