OHAUS Adventurer® Pro Advanced Precision Balance

Overview

The OHAUS Adventurer® Pro Advanced Precision Balance is an engineered solution for laboratories and industrial quality control environments requiring high repeatability, regulatory compliance, and operational versatility. Built upon electromagnetic force restoration (EMFR) technology, it delivers stable, drift-compensated measurements across diverse environmental conditions—including variable temperature, airflow, and vibration. Its modular architecture supports seamless integration into GLP/GMP workflows, with design features aligned to ISO/IEC 17025, USP , and ASTM E898–22 standards for analytical balance performance verification. Unlike basic weighing instruments, the Adventurer® Pro incorporates dual-sensor thermal compensation and adaptive filtering algorithms to minimize settling time without sacrificing resolution—enabling consistent accuracy at full capacity and sub-milligram readability.

Key Features

• Electromagnetic force restoration (EMFR) sensor with auto-zero tracking and dynamic drift compensation
• Configurable environmental settings: adjustable filter response (Fast/Medium/Slow), air current damping, and auto-stabilization threshold
• Comprehensive application modes: standard weighing, parts counting (with auto-average weight update), percentage weighing, checkweighing, statistical analysis (mean, SD, CV, min/max), and hold-to-display
• Dual-line backlit LCD display with customizable contrast and brightness; real-time status icons for overload, underload, calibration, and battery level
• Robust mechanical construction: stainless steel weighing pan, die-cast aluminum base, ABS housing with anti-static side sliding doors and top flip-up draft shield
• Full software protection suite: password-protected menu lock, user-defined operator IDs, configurable data print formats, and audit-ready software reset log
• Flexible connectivity: RS232 and USB Device ports; compatible with OHAUS Logger Pro™ and third-party LIMS via ASCII or Modbus RTU protocols
• Regulatory-ready functionality: built-in 21 CFR Part 11-compliant user access control, electronic signature support (via optional software), and traceable calibration history storage

Sample Compatibility & Compliance

The Adventurer® Pro accommodates a broad spectrum of sample types—from fine powders and hygroscopic solids to irregularly shaped components and liquid-filled containers—thanks to its large pan options (up to 168 × 180 mm), low-profile draft shield geometry, and optional below-balance weighing hook. All models are certified to OIML R76 (E2 and F1 classes) and meet ASTM E617 Class I and II requirements for precision balances. Units designated with “C” suffix (e.g., CAV214C) fulfill stringent metrological criteria for calibration laboratories, while non-C variants maintain full traceability to NIST standards through factory-certified calibration reports. The IP42 enclosure rating ensures reliable operation in non-sterile production areas where incidental dust ingress or light condensation may occur.

Software & Data Management

OHAUS Logger Pro™ software (included) enables automated data capture, customizable report generation, and secure export to CSV, PDF, or Excel formats. Each balance stores up to 1,000 measurement records locally with timestamps, operator ID, and environmental metadata. Communication parameters—including baud rate, parity, and data format—are fully programmable via front-panel menu or remote command set (OHAUS ASCII protocol). For enterprise deployment, the device supports SCADA integration via Modbus RTU over RS232 and is validated for use in FDA-audited environments when paired with validated SOPs and change-controlled firmware versions (v3.2+). Audit trails record all critical events: calibration, configuration changes, user login/logout, and error resets.

Applications

• Pharmaceutical QC labs performing assay uniformity testing per USP and content uniformity analysis
• Materials science research requiring precise mass determination before/after thermal treatment or solvent exposure
• Food & beverage production lines conducting ingredient batching, portion control, and net weight verification
• Chemical manufacturing facilities executing raw material receipt inspection against ISO 80000-1 mass metrology guidelines
• Academic teaching labs where student-accessible yet tamper-resistant instrumentation is required
• Environmental testing labs preparing standardized reference samples for ICP-MS or GC-MS analysis

FAQ

What calibration standards are supported?
The Adventurer® Pro accepts both internal calibration (on select models) and external calibration using OIML-certified weights compliant with ASTM E456. Calibration certificates include uncertainty budgets traceable to NIST SRM 31a.
Is the balance suitable for GxP-regulated environments?
Yes—when deployed with enabled security features (user roles, audit trail, electronic signatures), it satisfies ALCOA+ data integrity principles and supports 21 CFR Part 11 compliance through documented validation protocols.
Can the draft shield be removed for oversized samples?
The top flip-up shield and side sliding doors are removable without tools; however, removal invalidates OIML certification for that session—users must revalidate stability and repeatability post-reinstallation.
How is battery life managed during extended field use?
With four AA alkaline cells, typical runtime exceeds 120 hours in standby mode and 40 hours under continuous weighing cycles; low-battery warning activates at 15% remaining charge.
Are firmware updates available, and how are they applied?
Firmware v3.2 and later are distributed via OHAUS Support Portal; updates are installed via USB flash drive using guided on-screen prompts—no PC required.
