BUILT IN AIR PUMP

No air compressor needed. Just connect staright to your vehicle's 12V battery and generate smoke in seconds!

2 kinds of modes: AIR model+Smoke mode

Air mode :First, use the air mode to directly measure the leak, and judge whether there is a leak by the pressure gauge value. If it is less than 0.5bar, it will inevitably leak. If it reaches 0.8bar and above, the pipeline tightness is very good.Then there is no need to waste baby oil

SMOKE MODE:After the air mode determines that there is a leak, use the smoke mode to find the leak.

How to work with ancel s300 smoke leak detector?

Step1: Fill in 10ml-20ml test oil (baby oil) to the detector
Step2: Disconnect the pipe that needs to be connect with the detector
Step3: Connect detector with DC12V battery,device starts to work
Step4: The pipe will be filled with smoke,check the leak points

Adjustable Flow Meter

Air Flow meter with ajustable button, easy to control the smoke effect(output flow:<7L/Min)

How to judge leakage- through the pressure gauge?

NO Leak: When the value of the pressure gauge remains unchanged and the flow meter will read zero (ball at bottom of scale), it means that there is no leakage in the system.

Small Leak: When the value of the pressure gauge drops and the ball in the flow meter slowly fall to the bottom of the scale, it indicates a small leak in the system.

Massive Leak: When the value of the pressure gauge reaches zero and the flow meter ball never falls to the bottom of the scale, it indicates a large leak in the system.
