• Waterproof and floating IP67 case
• Unit of measure is displayed along with reading

• Built-in timer
· Built-in reaction timer that ensures consistency between tests.
• Error messages on display
· Alerts to problems including no cap, high zero, and standard too low
• GLP data
· Displays the last calibration date.
• Auto logging
• Battery status indicator

• Auto-shut offate and instruction manual. CAL Check™ standards and test reagents are sold separately.

Advanced LED optical system
· Innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette.
· LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability.
