SCR-803 Urea Pump Controller SCR Aftertreatment System Tester

Product Overview: The SCR-803 Urea Pump Controller

In the field of diesel engine maintenance, the efficiency of the SCR (Selective Catalytic Reduction) system is paramount. Today, we are introducing the SCR-803 Urea Pump Controller, a versatile diagnostic tool designed to test and maintain the aftertreatment systems of modern diesel vehicles.

This device is perfectly compatible with both Windows and Android operating systems, allowing technicians to install the test software on laptops, tablets, or smartphones for maximum flexibility.

Key Testing Capabilities

The SCR-803 is not just a pump tester; it is a comprehensive system analyzer. Its main interface allows users to select between Urea Pump tests, Sensor tests, and System Settings.

1. Urea Pump Testing
The device supports a wide range of urea pump models, ensuring broad vehicle coverage. Compatible brands and models include:

• Bosch: 2.2, 6.5 (12V/24V)

• Cummins: Ecofit, UL2

• Emitec: SanLi (12V/24V), Cummins 24V/12V

• Other Brands: Tenneco, Albonair, Hilite, Kailong, PowerGreen, WeiFu, QinTai.

During testing, the controller can perform critical functions such as:

• Pre-injection pressure build-up: Evacuating air and establishing pressure.

• Flow Injection: Testing Large, Medium, and Small flow rates.

• Clean/Purge: Automatically purging the pipeline before dismantling to ensure safety.

2. Nitrogen and Oxygen (NOx) Sensor Testing
The SCR-803 allows for precise testing of 12V and 24V NOx sensors. The testing process takes approximately 5 minutes:

• The sensor is automatically heated (Warning: Do not touch the metal part during testing!).

• It measures Oxygen concentration (%) (approx. 20% in air) and NOx concentration (ppm) (0-30 ppm in air).

• This data helps determine if a sensor is damaged or functioning correctly.

3. Liquid Level and Temperature Sensors
The device measures the resistance value of liquid level and temperature sensors.

• Liquid Level: You can manually slide the float on the sensor to observe real-time resistance changes on the screen.

• Exhaust Gas Temp: Supports PT100, PT200, and PT1000 sensor types.

Connectivity and Upgrades

The SCR-803 makes connection easy via Bluetooth or USB.

• Android: Connects via Bluetooth (Default Pairing PIN: 1234).

• Windows: Connects via USB cable or Bluetooth.

Additionally, the system features an Online Upgrade function, ensuring your equipment stays up-to-date with the latest firmware and vehicle data.

Conclusion

With its ability to handle multiple pump brands, precise sensor diagnostics, and wireless connectivity, the SCR-803 Urea Pump Controller is an essential tool for any workshop specializing in heavy-duty diesel repair and emission system maintenance.
