如何使用
Add Oil, Connect, Power, Inspect, and Retest
添加測試油
Fill 10–15 mL baby oil or liquid paraffin into the detector before first use. Do not exceed this range.
連接測試線
Access the system to be tested and position the detector near the test area. Disconnect the line you want to test, then connect it to the smoke hose.
開始開發
Connect the detector to a 12V DC battery. Confirm that the smoke hose and test line are connected securely, then turn on the power switch.
尋找洩漏點
大約30秒後,連接的測試管路將充滿煙霧。檢查是否有煙霧逸出,以查找洩漏點,必要時可使用頭燈。
確認並複測
確認系統佈局中是否存在可見的洩漏路徑,修復已確認的洩漏點,並重複相同的受控測試。如果未看到煙霧或故障是間歇性的或功能性的,則繼續執行車輛操作程序。
安全性和相容性
Confirm System Pressure, Ventilation, and Connections
12V電源和內置氣泵
The built-in pump supplies test airflow after SDT50 is connected to a 12V DC battery.
Add 10–15 mL of Testing Oil
Use liquid paraffin or baby oil as testing oil. Add 10–15 mL before first use and do not exceed 15 mL at one time.
連續使用時間限制為 8 分鐘
Do not run SDT50 continuously for more than 8 minutes. If the internal temperature exceeds 75°C, the unit shuts off automatically. Let it cool before restarting.
工作溫度和高溫表面
SDT50 支援在低至 -20°C 的溫度下運作。圓形金屬外殼在使用過程中可能會發熱,因此請避免直接觸摸高溫表面。
Check Connections Before Starting Smoke
Before starting smoke, make sure the smoke hose and test line are connected securely. Follow the vehicle or component service procedure, and do not introduce smoke into any system where smoke testing is not permitted.
利用煙霧定位洩漏點
利用可見煙霧定位洩漏區域,然後進行修復並重新測試。如果沒有煙霧出現,請在繼續操作前重新檢查隔離、流量和測試裝置。
切勿在運作過程中加油
SDT50 運轉時請勿添加測試油。
No Pressure or Airflow Measurement
Do not use SDT50 to measure pressure or airflow.
Cool Before Restarting
Let the unit cool before restarting after overheat protection is triggered.
避免高溫金屬外殼
金屬外殼發熱時請勿觸摸。

常見問題
Power, Pump, and Smoke Questions
Does SDT50 Need an External Air Pump?
序號 AUTOOL SDT50 has a built-in air pump, so it does not require a separate air supply or extra air pump for normal smoke leak detection.
我應該使用哪種測試油?
Liquid paraffin and baby oil are both acceptable testing oils for SDT50. Replace the testing oil regularly, and drain remaining old oil before adding fresh oil.
How Much Oil Should I Add?
Fill 10–15 mL oil before first use. Do not exceed this range. Fresh oil can be added only when smoke becomes thin, and do not add more than 15 mL each time.
SDT50 需要什麼樣的電源?
SDT50 must be connected to a 12V DC battery and is designed for 12V DC vehicle leak checks.
SDT50 可以連續運作多久?
Do not run the detector continuously for more than 8 minutes. Allow the unit to rest between operating cycles.
Why Did the Unit Shut Off Automatically?
If the temperature exceeds 75°C, automatic overheat protection turns off the power. Let the unit cool before restarting.
Is Any Part of the Detector Hot During Operation?
Yes. The round metal housing can become hot during operation. Avoid direct contact to prevent burns.
Should I Avoid Any Parts During Leak Detection?
Yes. Do not introduce smoke into any component or system that the vehicle or component service procedure excludes from smoke testing.
How Does SDT50 Differ from Other AUTOOL Smoke Leak Detectors?
- SDT50: Built-in pump, Smoke Mode, <10 psi, <5 L/min, 50 W, 1.5 kg.
- Add pressure monitoring: SDT60.
- External-air EVAP: SDT101/103.
- Separate Air + Smoke modes: SDT205/205S/206/208; SDT208 also provides 35 psi Standard and 10 psi EVAP.

Good smoke effect
Very good quality, better than other brands I have used before. This smoke leak detector has a built-in air pump. It is small and easy to carry. I can use it easily. The smoke effect is good. A lot of smoke is produced in 20 seconds. I use baby oil.

Pipe inspection is very useful.
Pipe inspection is very useful. Although it is very small, it has a built-in air pump, so it can be used for inspection at any time without the need for an additional air source, providing greater convenience. I am very satisfied with it.

The smoker is a great product, portable and lightweight, I used the Johnson’s baby oil they recommended to go with it, it’s an amazing combo, but the smoke comes out very well, I have a repair tool sales store, can I resell it please? Please contact me, thanks!
