Wöhler DC 420 - for sewer pressure testing
The digital device DC 420 is characterized by easy menu navigation and a unique ergonomic design. The digital device DC 420 is intended primarily for standard air testing of waste pipes according to DIN EN 1610. In case of immediate documentation of the measurement results, the digital device DC 420 can be connected to the thermal printer TD 600 (IrDA) or to a PC (mini USB). The main advantages of the digital device DC 420 include:
- Intuitive control of the test process using a brilliant color graphic display
- compact set in a suitcase - everything at hand
- printout of the graphic report directly on site
- Reel with metric markings, flexible GRP rod for precise and smooth positioning of the sealing bellows
- "intelligent" valve block for flawless connection of all components
- brilliant color display
- large measuring range: 1 Pa to 2 bar
- data transfer to PC via USB
Main use of the device
- for standard waste pipe testing
- carrying out the main air test of the sewer according to EN 1610
- for measuring volume
