View Ancel productsProduct information
The Ancel S300 is an auxiliary test equipment used for workshops that want to check for leaks in EVAP, vacuum lines, hoses, and intake systems with smoke. It is not an electronic fault code reader; it supports suspicion of mechanical leaks with visual inspection after fault code and live data.
Vehicle and part coverage
A make-model software list, as found in diagnostic devices, does not apply to this product. Compatibility is determined by the part to be measured, the electrical system, the operating range, the probe or connection method, and the manufacturer's safety limits.
Product details
The S300 helps visually track leaks by applying controlled smoke to closed lines. On the ANCEL official product page, the device is described as an automotive EVAP smoke machine; its output pressure is listed as 0.8-14.5 psi, output flow below 6 L/min, and air pressure output as 0.8-1.0 bar.
Product details
For smoke testing, the connection point, adapter selection, test fluid, and the system's pressure tolerance are as important as the device. High pressure should not be applied without considering the service procedure of the line to be tested and the manufacturer's pressure limit.
Product details
The S300 does not offer fault codes, live data, or service resets. Diagnostic devices such as DS500BT, DS600, or similar are used for electronic diagnostics; the S300 is service equipment that complements leak suspicion with smoke testing.
Product details
The S300 model is a leak detector used to find leaks in EVAP, vacuum, and closed air lines by making the smoke exit point visible. Its main uses and hardware features include: EVAP leak testing, vacuum line check, and hose sealing.
The S300 model performs its own testing or support tasks; it does not replace a full system diagnostic tool.
Product details
The S300 model searches for leaks in the EVAP line by making the exit point of the smoke, delivered at low pressure, visible. The 0.8-14.5 psi pressure information is compared with the permissible limit of the test line before the device is connected. The S300 model helps visually inspect cracks, loose clamps, or gasket leaks in vacuum hoses and connection points.
The 12V power connection, smoke hose, and test adapter are checked before use. The S300 model re-tests the same line after repair to show if smoke is still exiting. The accessory kit information helps ensure the first test and final check are performed with the same connection setup.
When the S300 model applies smoke to a line, the leak point is visually monitored and the connection area is recorded. After repair, the same pressure and connection setup is used for re-testing to check for leaks.
Product details
When searching for EVAP leaks with the S300 model, the test connection specified by the vehicle manufacturer is used. The hose and appropriate adapter are securely attached to the closed line. The device is connected to a 12V power source, and the pressure is kept within the limit allowed by the system.
The valve, hose, gasket, or connection area where the smoke exits is visually recorded. Once the leak location is identified, the system pressure is released, and a repair plan is written.
Product details
The S300 model makes cracks in hoses, loose clamps, and leaking connections visible during vacuum line checks. The open ends of the line to be tested are properly sealed. Smoke is applied to the line at low and controlled pressure. The point where the exit is seen is added to the service record with the line name and vehicle information.
At the end of the test, the pressure is released, and the hoses are disconnected in a safe sequence.
Product details
For post-repair seal checks with the S300 model, reconnect to the connection point used in the initial test. The same adapter and permissible pressure value are used. Smoke exit is observed in the repaired area and at other connections of the line. No smoke observed indicates the result for only the tested line under those conditions.
The initial finding and the final check are explained together in the customer report.
Product details
The 0.8-14.5 psi pressure, 12V power connection, and accessory package define the connection and operating limits of the smoke test. ANCEL technical data specifies the output pressure as 0.8-14.5 psi, output flow below 6 L/min, and air pressure output as 0.8-1.0 bar. The device operates with a 12V power connection.
The permissible pressure for the line to be tested is obtained from the vehicle manufacturer's service procedure; the product's maximum output value is not applied to every line. The hose, cone adapter, and connection clips are specified by name in the package contents.
Product details
The use of the S300 model begins with finding the correct connection point of the line to be tested. The hose and appropriate adapter are attached to the closed line, and the device is connected to a 12V power source. The pressure is kept within the limit allowed by the vehicle manufacturer, and the smoke exit point is observed.
The leak area is recorded, the repair is completed, and the line is re-tested under the same conditions. At the end of the job, the pressure is released, and the connections are disconnected in a safe sequence.

FAQ
No. The S300 is for smoke leak testing; it is not an OBD fault code reader.
It is used in lines where visual leak detection with smoke can be performed, such as EVAP, vacuum, and intake lines, and hoses.
Smoke testing visually supports leak suspicion. The result is interpreted with the system structure, correct connection point, and the vehicle manufacturer's service procedure.
The S300 model is a leak detector used to find leaks in EVAP, vacuum, and closed air lines by making the smoke exit point visible; it is directly used for EVAP leak testing in daily service.
The 0.8-14.5 psi pressure, 12V power connection, and accessory package are checked before the S300 model is connected or the test is started. Measurements, images, or physical test results are recorded according to the S300 model's operating range.
No. The S300 model is used only with the permissible pressure limit of the closed line being tested and the correct connection adapter. The pressure to be applied to the EVAP, vacuum, or another line is taken from the vehicle manufacturer's service procedure; the same setting is not used for every system.
During the first use of the S300 model, the hose, cone adapter, power clip, 0.8-14.5 psi pressure, and pressure gauge are checked. The device is connected to a 12V power source. An EVAP leak test is attempted within the manufacturer's specified pressure limit, and the smoke exit point is recorded.
The S300 model performs its physical function without its own software subscription; main device software may be required for modules operating with a compatible main device. S300 warranty and parts support are shown under the conditions of the purchased package.
An update period not related to this physical product is not listed as a product feature for the S300 model.
