The Fotoimpex CHM 400 Universal is a black and white film. It was introduced in 2004 and is now back in the range of Fotoimpex, the photo distributor from Berlin. The people behind Fotoimpex are also behind Adox.
However, this black and white film is only produced for the Berliners. Presumably, it is the British Ilford. Currently, the CHM 400 and CHM 100 are only available for 35mm cameras. One cartridge is enough for 36 pictures.

The film has a rated sensitivity of ISO 400, and is designed for black-and-white images. According to Fotoimpex, it can be pushed to ISO 800 without any problems. The Fotoimpex CHM 400 Universal must be developed as a classic black-and-white film. This requires a black and white developer and a fixer.
