ANCEL L300 Car Leak Detector： ⛳【UPGRADE 1-DIGITAL PRESSURE GAUGE】The L300 is the latest advanced automotive smoke machine introduced by ANCEL in 2024. Digital pressure gauge design offers more accurate data compared to traditional mechanical pressure gauge. It can provide precise readings in multiple units(Psi, bar, kpa, kg/m), helps you effectively monitor pressure changes in real-time while performing leak detection. With ANCEL L300, you can detect all types of leaks like vacuum pipe leak,crankcase air leak, intake pipe air leak, exhaust pipe air leak, throttle air leak, fuel tank air leak, various connectors air leak, window air&water leak and even the tiniest of leaks ⛳【UPGRADE 2-VACUUM(NEGATIVE PRESSURE)TEST】Traditional mechanical pressure gauges cannot display negative values, making it difficult to accurately detect leaks in some negative pressure environments. The L300 smoke tester's digital pressure gauge can display both positive and negative values. The normal output voltage is between 0.8-1.2 bar. When detecting negative pressure environments such as vacuum pipes, the closer the negative value is to 0, the more severe the leak is. When detecting positive pressure environments, the lower the positive value is below 0.8 bar, the more severe the leak is. The pressure unit can be set according to personal preference ⛳【UPGRADE 3-SMOKE COLUMN TEST】The L300 car smoke machine has a specially added accessory, the "smoke diffuser" . Simply set your vehicle to the recirculation mode and connect the supply hose nozzle to the diffuser, it can evenly disperse smoke in a column-like shape. The smoke then moves along the sealed components being tested. If the smoke column is distorted or dispersed, it indicates a leak. This process highlights the dispersion of smoke to aid in locating the leak point, making the issue easier to identify ⛳【AIR & SMOKE DUAL WORKING MODES】Switch modes with one button. In air mode, this evap smoke leak detector can determine if there is a leak in the system by detecting the gas concentration in the air. In smoke mode, it can locate and detect leaks in the whole system of the car by generating visible smoke, and with the adjustable flow meter, it can control the amount of smoke in real time. Highly improves the accuracy and efficiency of the detection ⛳【SAFE TO USE】Made of stainless steel, resistant to impact and wear; Exclusive isolated heat transfer technology with overheat and anti-frost protection; No need to start the car, allowing for convenient operation at any time; Lightweight and compact, easy to hang and causing no excessive burden on the vehicle; Non-toxic smoke, harmless to both the vehicle and human. Ensure a safe and user-friendly experience when using the automotive smoke leak tester ⛳【EASY TO USE WITH BUILT-IN AIR PUMP】Simply pour in the smoke oil, connect the 12V power supply,and press one button to start, instant and odorless smoke will be generated. This smoke tester automotive comes with a built-in air pump, eliminating the need for additional purchases. The back is designed with a visible window, allowing you to observe the position of the oil at any time. 🚩Please note the oil should not be overfilled, keeping it between the min and max values ANCEL L300 Advanced Technology ✔️ Crankcase system test ✔️ Intake System Test ✔️ Car Sealing Test ✔️ Fuel Tank System Test ✔️ Turbo System Test ✔️ EVAP System Test ✔️ Exhaust Systems Test ✔️ Various Pipe Fittings Test  ANCEL L300 Main Features:
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.

Knowledge for Fuel Vapor Recovery System (EVAP) 1．According to the Environmental Protection Agency, the EVAP system is the most neglected of all the emission systems in an automobile. A leak as small as 0.020” diameter can allow over 30 times the allowable hydrocarbons into the atmosphere then is currently acceptable through the exhaust. Additionally, EVAP system leaks can be a major cause of check engine lights occurring. In the past, EVAP related problems have been difficult to locate and repair. These can now be quickly diagnosed and repaired, becoming a profitable ticket for service facilities. 2．There are several acceptable methods of inspecting the EVAP system. Basically we need to close any vent solenoids, fill the system with smoke, and look for the smoke escaping at the leak. Since these systems vary in different vehicles and have evolved over the years, we will attempt to describe operating guidelines that should be helpful in inspecting these EVAP systems. 3．Beginning with the 1996 model year, U.S. Vehicles have been produced with an EVAP Service Port to access this system. The port is usually located under the hood, but may be located else were on the No Leak Small Leak Massive Leak Flow Meter drop to ‘0’ and pressure reading raise to Max. Flow Meter stay between 0.1 to 0.5LPM. Flow Meter raise and pressure reading drop to ‘0’.vehicle. To access this port for testing, remove the cap, then remove the Schrader Valve from inside the 4．The Onboard Diagnostics on vehicles 1996 and beyond will determine if a leak exists, the following trouble codes may be indicated to report the leak: 5．Using a scan tool, close the vent solenoids so that the EVAP system is closed to the atmosphere. 6．Set up the machine 7．Remove the fuel cap and begin to fill the system through the Service Port Adaptor until dense smoke is seen exiting the fuel neck. This procedure ensures that the system is full of smoke. Replace the fuel cap and continue pumping smoke into the system. 8．Inspect under the hood for leaks using a bright halogen lamp. Raise the vehicle on a hoist and inspect the underside of the vehicle, tracing the route of the EVAP system. Note: It may be necessary to hang the Smoke Machine under the car so that it is visible to the operator 9．As the system fills with smoke, and the pressure in the system equalizes, keep an eye on the Flow meter and the Pressure Gauge. If there is no leakage in the system the Pressure Gauge will go to its maximum pressure and the Flow meter will drop to zero. 10．For trouble code P0456, the meter should stabilize at 0.1 LPM or less with the Smoke Machine. 11．For trouble code P0442, the meter should stabilize at 0.5 LPM or less with the Smoke Machine. Note: These readings are approximate and are for reference only. 12．Once the leak has been located and repaired, it is a good idea to repeat the above procedure using air only. It is not necessary to turn on the smoke to test for leakage using the flow meter. 13．Replace Schrader Valve and cover. (Note: Valve is Left-hand thread.) 14．Following are some generic OBD EVAP related codes: |
