Microprocessor Control

• Fully automatic and self-diagnostic system monitors and controls working condition.
• PIN-coded access to software set points prevents unauthorized changes to operation or system settings.

Comprehensive Sanitization

• Unlike many other systems, Dofree entire fluid pathway is included in the automated disinfection process ensuring complete sanitization.

Module-designed Cartridges

• High quality and economical due to disposable integrated purification column design.
• Easy replacement and quick connection.

High precision resistivity meter

• Flow-through structure make sure the real-time measurement of the actual ionic concentration in water
• Low cell constant (0.01cm-1) to ensure optimum measurement accuracy of low ionic contamination
• Automatic temperature compensation (0.1℃ resolution) makes the value displayed on the screen meaningful

Easy-to-read LCD display

• User-friendly LCD provides optimal convenience, with indication on resistivity and reservoirs water consumable changing reminder water quality.

Optional strengthened pre-treatment module

• 20′ size long cartridge contrains detergent. Therefore, besides the feature of higher water throughput, feed water with extremely low quality can be properly dealt with

Contamination-Free Water Tank

• Water level sensor combined with bottom pump enables 5-level automatic water production controls
• Capacity of water reservoir includes 30L and 60L. Moreover, ultra big 350L water reservoir is available for special needs
• The water reservoir is made through cylindrical mold and blow molding process to avoid the generation of velum
• PE material ensure low extractives
• Overflow protection tube eliminates the risk of flooding
• Cone shape bottom guarantees no stagnant water and facilitates easy clean
• Optional UV lamp and vented filter maintain consistent purity of stored water and provide effective protection against airborne contaminants

Network Compatible

• RS232 port allows for data collection and permanent record of water quality and system parameters, with date and time, to a PC or printer – essential for compliance with good laboratory practice guidelines
