OHAUS Explorer Analytical EXR Analytical Balances
Manufactured by Ohaus
Offering 11 weighing applications including differential weighing and dynamic weighing, the Ohaus Explorer Plus™ Analytical EXR analytical weighing balance provides dependable and accurate laboratory measurements.
The digital weighing components (DWC) offer the advantage of creating self-contained load cell modules. Rapid and precise measurements with this advanced technology ensure weighing processes are both swift and highly accurate.
Both ISO 9001 calibration or UKAS 17025 calibration are available for this new generation of Ohaus analytical balances (For UKAS balance calibration, please contact us).
Important: For commercial transactions requiring verified weights, AML Instruments offers the Explorer ‘M’ certified models (e.g., EXR124M). These specialised balances are verified to meet or exceed UK/EU weights and measures regulations, providing Legal-for-Trade Compliance for businesses ranging from jewellery to industrial packaging.
Benefits
- 7-inch touchscreen display with vibrant colours, an easy-to-clean glass panel, and chemical resistance ensures a clear, durable, and intuitive interface.
- Internal calibration systems (automatic, user-triggered, and span calibration options) ensure precise measurements.
- Fast 2-second stabilisation time to boost efficiency.
- Digital level bubble enables you to check and if necessary adjust the instrument so it’s balanced.
- Four-level user system, password protection, and 100k internal system log ensures compliance and traceability.
- Draftshield has an anti-static coating to reduce static electricity around the balance for consistent results.
- Draftshield is easily removable for easy cleaning and long-term care, as well as specific large volume weighing applications.
- Customisable terminal status lights indicate the balance’s status – battery level, stability, etc.
- Apply to 11 weighing applications – large sample profile streamlines your workflow.
- 1000 sample libraries.
- Dedicated Sample Dosing Mode for powder sample application.
- Out-of-the-box packaging design means no assembly is required, saving you time and effort.
- Multiple USB ports offer unparalleled flexibility.
- Direct to Excel feature provides a basic yet highly user-friendly option for data transfer.
- Supports HID connection to PC or keyboard without drivers.
- Network Time Protocol (NTP) ensures accurate timekeeping and confirms data traceability to meet pharmaceutical regulations.
- Compatible with SICS command and easy to integrate to LIMS, MES system.
- Label printing function (2 preset templates and 10 customised templates) – Bluetooth printer available as add-on.
- Weighing pan made from SST 316 high-grade stainless steel offers superior corrosion resistance and assists the laboratory sample preparation process.
- Full metal housing provides robust protection for internal components.
- Models EXR224 and EXR324 are Green Lab ACT Ecolabel certified for their sustainable design. This includes reduced shipping weight, sleep mode which offers a 65% reduction in power consumption, and up to 58% of total components made from recycled materials.
