The AGO Film Processor brings professional-level control to your home developing set-up! A modern processor that handles the temperature, timing, and agitation intervals according to preset programmes for all common chemistries. You can also take full control with custom programmes you design and upload to your machine over WiFi.
Key Features
- Time Compensation. The AGO Film Processor has an inbuilt thermometer which informs the onboard computer, allowing it to adjust the time intervals of developing to account for the live chemistry temperature. Perfect developing every time!
- Automated Agitation. You can set the AGO film processor up to perform horizontal rotation or vertical stick agitation according to your preference*, and then leave it alone! It will run the programme according to your developing recipe, leaving you free to prepare the chemistry for the next stage. No more mistakes, or forgetting how long you have left!
- Paterson Compatible. The AGO film processor works with the world-famous Paterson developing system, to make it easy to build a system that works for you. Looking to do one 35mm roll at a time, or double stack 120? Both are possible – and so much more!
*Using horizontal agitation can save up to 60% of chemical usage versus vertical agitation – as shown below
