Simple Design For Maximum Reliability
No Pumps, no valves, no hoses
Two-axis mechanized robot arm
Minimal moving parts, mechanisms, and difficult-to-clean tight spaces
Reduces the types of materials exposed to strong oxidizing salts in photographic chemical solutions
Maximium process flexibility
Exposed Design for Ease of Care and Maintenance
Exposed motor drive mechanisms make preventive maintenance easier
Operation is easily observed, giving you an intuitive understanding of your machine
Unique Developing Tank Design
Load your film, pour in chemicals, wait for completion, hang to dry
Light-tight base permits passage of liquids in and out of the tank
Light-tight lid permits air to flow in and out as the liquid levels rise and fall
Agitation is provided by partial lifting and lowering of the tank during the development cycle
