Description
Measure the total osmolality of any aqueous solution using Freezing Point Depression principle
Key Features for OSM100100 / OSM100201

• Built-in large touch screen for intuitive operation of the instrument.

• High-precision sensor guarantees accurate measurements & repeatability.

• Molar concentration, freezing point, molar concentration ratio are measured.

• Multipoint calibration (2 or more points) with any standard concentration.

• Refrigerant-free cooling and therefore less maintenance requirement.

• Micro-computer controller can automatically process and store data.

• Dual refrigeration system for faster cooling and continuous testing.

• Small sample quantity requirement for testing.

• Built-in printer with multiple printing format settings.

Key Features for OSM100301

• Process multiple samples (1-20) automatically and continuously.

• Its rotary turntable design with an elevated probe enables walk-away continuous and batch measuring.

• The instrument features a large, built-in touchscreen running an Android operating system, providing intuitive control and real-time display of its running status.

• High-precision sensor guarantees accurate measurements & repeatability.

• Molar concentration, freezing point, molar concentration ratio are measured.

• Achieve high precision with multi-curve calibration, perfectly fitting measured sample at any concentration.

• Refrigerant-free cooling and therefore less maintenance requirement.

• Micro-computer controller can automatically process and store data.

• Small sample quantity requirement for testing.

• Print test results directly via the built-in printer (with various format options) or export them in Excel or CSV files via USB port .

• Connects to PCs or laboratory management systems via RS232.

• It features a 10-level access management system, ensuring secure and flexible operations, allowing higher-level users to grant access to those at lower levels

• USB connectivity allows you to connect external devices like a mouse, keyboard, and scanner, as well as transfer data to a PC.

• Audit trail feature with electronic signature enables data traceability.

• Designed for quiet operation in noise-sensitive locations.
