CRI808S Bluetooth Common Rail Injector Tester with AHE Function

CRI808S Bluetooth Common Rail Injector Tester with AHE Function

Meet the CRI808S, the next-generation compact Common Rail Injector Tester designed for precision, convenience, and modern connectivity. Whether you are testing standard electromagnetic solenoids or advanced Piezo injectors, this device delivers professional-grade performance in a highly portable package. Its standout features include Bluetooth Android mobile control and the highly sought-after AHE (Armature Lift) function, making it a must-have for advanced diesel technicians.

Core Features & Advantages

• Smart Bluetooth Control: Ditch the heavy equipment. The CRI808S features a built-in Bluetooth antenna, allowing you to control and monitor the testing process directly from your Android mobile phone.

• Comprehensive Brand Support: Fully capable of testing standard oil and Piezo injectors from major brands including BOSCH, DENSO, DELPHI, SIEMENS, Piezo, and Caterpillar.

• AHE Function (Dynamic Stroke): Includes Armature Lift (AHE) testing capabilities, a critical metric for precision injector rebuilding and calibration.

• Multiple Working Modes: Easily simulate different engine conditions with preset modes: VL (Full Load), TL (Emissions), LL (Idle), and VE (Pre-injection).

• Customizable Parameters: Freely adjust the injection pulse width (06000 uS) and frequency (130 Hz). It also supports a counting function to set an exact number of injections for targeted testing.

• Compact & Lightweight Design: Weighing only about 0.435kg and measuring 130x120x45mm, its robust aluminum shell makes it perfect for both bench testing and mobile diagnostics.

Application Scenarios 

• Mobile Diagnostics: Because it weighs less than half a kilogram and can be controlled via an Android smartphone, it is the ultimate tool for mechanics who travel to job sites or do field repairs.

• Precision Injector Rebuilding: The built-in AHE (Armature Lift) measurement function makes it ideal for specialized diesel workshops that need to adjust the dynamic stroke of Bosch injectors during the rebuild process.

• Quick Bench Testing: Pair it with a manual nozzle tester (pop-tester) to quickly check the spray pattern, atomization, and response time of an injector before full calibration.

FAQ 

Q1: How does the Bluetooth mobile control work?
A: The CRI808S has a built-in Bluetooth antenna. You can download the dedicated Android application to your smartphone, pair it with the tester, and adjust settings like pulse width, frequency, and working modes directly from your phone screen.

Q2: What is the AHE function and why is it important?
A: AHE stands for Armature Lift (or dynamic stroke). It is a critical measurement when rebuilding common rail injectors (especially Bosch). Setting the correct armature lift ensures the injector delivers the precise amount of fuel required by the engine.

Q3: Can this device test Piezo injectors?
A: Yes! The CRI808S is fully equipped to drive advanced Piezo injectors, and the package includes a specific Piezo adapter cable plug for safe and accurate testing.

Q4: Is the power supply suitable for my country?
A: Yes, the package includes an external power adapter that accepts a wide input voltage of AC 100-240V, converting it to the DC 24V required by the host machine. It can be used globally.

Q5: How do I navigate the menu on the device itself?
A: Aside from the phone app, you can use the intuitive rotary knob on the front panel. Rotate the knob to move the cursor or modify parameters (like Min/Max frequency), and press the blue Start/Stop button to execute the test.
