OHAUS EX125/D| EX225D/AD| Explorer Semi-Micro Balance
When laboratory work and research requires accuracy to the hundred-thousandth, there is simply no room for error. The Explorer series of semi-micro balances 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.
Unique Features Include:
• Explorer’s weighing cells precision-machined from a solid metal block, together with AutoCal™ provides exceptional accuracy and durability suitable for laboratory and industrial environments.
• Features such as four-level user management with password protection, and un-editable system log plus a high level of configurability make Explorer balances well suited for regulated applications.
• A detachable terminal with a large color touchscreen, programmable IR sensors, optionalbuilt-in Ionizer & automatic doors, and a frameless draftshield make Explorer balances
easy & convenient to use.
Weighing Performance
OHAUS’ signature AutoCal™ internal calibration system ensures the balance is always ready for use and eliminates the need for manual routine calibration. Explorer’s internal calibration mechanism uses
multiple weights and adjusts the balance at several points within the weighing range; this results in lower measurement uncertainty than a simple span calibration. Additionally, Explorer balances feature
a built-in Repeatability Test, which helps evaluate the balance’s performance and aids in determining a suitable minimum weight for applications requiring high accuracy.
Connectivity
Explorer balances include a series of communication interfaces including RS-232, USB, and Ethernet, allowing accessories such as RFID readers, impact printers, label printers and barcode scanners to
be connected to the balance. A simple yet complete communication protocol allows Explorer balances to be easily connected to a PC or integrated with larger systems.
Data Management
Explorer balances are equipped with internal databases, which can be used to store, manage, and retrieve application and system data. An internal weighing mode library allows saving and loading of
weighing mode configurations. Explorer balances offer two types of log files. One is the system log file which records up to 5000 changes to the balance’s settings, calibrations and adjustments, and
user access. The other is the calibration log which tells you when last calibrated the balance. Both log files can be exported as a noneditable PDF file and saved onto a USB memory stick. A built-in real time clock ensures that the data captured is contemporaneous.
User Management
The user management system allows a system administrator to create up to 110 users and assign them to 1 of 4 pre-existing groups with varying access rights to the balance and enforce password protection ensuring data integrity in a multi-user environment.
