Weighing booth, aslo called sampling booth or dispensing booth, negative pressure booth or pharmaceutical booth, is a dedicated purification equipment for sampling, weighing and analysis. It can contain powders and particles within work area and prevent operator from inhaling them.

1. Automatic changeable frequency system monitors the air velocity to ensure its stability in the work area.
2. Differential pressure gauge is equipped to real-time monitor the filters.
3. Unique designed air duct effectively controls the noise.
4. Uniform flow design of main working area can protects the operators and prevent environmental pollution and cross contamination
   of products.
5. Intelligent control mode and alarm system ensure the reliability of running.
6. Smooth transitions of wall and ground can eliminate the blind angle.

Factory test include:

• appearance testing
• functional test and visual inspection
• air velocity testing
• noise testing

This instrument is applied for pharmaceutical, microbiological, scientific experiments, food industries and hospital operating rooms.

Before debugging, we must verify that the connection of the wires is correct, and the debugging personnel to be familiar with the instrument. And we should read the instruction carefully.
