Super negative pressure

The maximum load capacity exceeds 30Kpa, making it easy to handle high resistance enrichment carrier sampling (TVOC, benzene derivatives, etc.)

Digital constant current

Built in high-precision sensors, precise closed-loop control, no need to worry about your flow deviating!

Double sided encapsulation

The human-machine engineering design concept enhances the instrument's tactile comfort and improves the machine's drop resistance.

Human Machine Engineering

Compliant with ergonomics design, the fuselage is horizontally designed, and the back clip is horizontally fixed at the waist of the staff, allowing for 360 ° displacement to perform various tasks.

Multiple protections

The efficient protection design of the intake filter and the pre drying anti backflow suction bottle provide multiple protections to prevent particle and moisture damage to the instrument.

Ultra long battery life

Fully charged once, it can work continuously for 40 hours @ 100mL load 10Kpa, without the need to arrange charging before each work.
