Features
● High accuracy weighing
Calculating changes in the weight value and controlling the valve opening allows discharge to be controlled in units of 1g.
● Quickly weighing
Quickly weighing is possible by means of automatic setting of valve opeing amount.
● Superior ease of cleaning
Because all parts which contact the powder consist of flexible silicon tubing, they can be easily disassembled, reassembled and cleaned.
● No metal contamination
There are no mechanical parts inside system and the structure is enclosed, preventing contamination.
● Support for a wide range of powders
By installing a TFB-mini (Breaker Boy), vibrator, or knocker onto the hopper, this system can be used for various powders.
● Low price
By simple configuration, it is a good value for the price.
