CR508S Common Rail Pressure Tester and Simulator


The CR508S is a professional-grade diagnostic and programming device that offers comprehensive functionality for various vehicle systems. With its user-friendly interface and advanced features, the CR508S enables users to quickly diagnose and troubleshoot issues in the engine, transmission, ABS, airbag, and more. Additionally, it supports a wide range of vehicle models and provides access to essential vehicle data for efficient repairs. 




Top 6 Reasons to Get CR508S Common Rail Pressure Tester and Simulator:


1) CR508S is the latest upgrade rail pressure tester, it can test kinds of common rail

pressure sensors of diesel engine, include BOSCH,DENSO,DELPHI.

2)  CR508S is a portable fuel-way pressure tester and simulator. Except test, CR508S also

can be used for simulating fuel pressure that universal scanner can’t have. By simulation,

users can stimulate conveniently for searching problems on fuel way.

3) CR508S Diesel Engine common rail pressure test can be operated simply with high

accuracy avoiding the complicated operation compared with the previous use of

mechanical pressure gauge pressure tube  and  problem caused by other factor entering

a damaged fuel injector and the pipe damage , a series of negative effect caused by oil

spills .

4) CR508S greatly improves the working efficiency.Most importantly according to the

standard data to search for the engine starting difficulty and power caused by the lack of

engine fault alarm The instrument is enclosed with standard operating rail pressure data

and details of the fault that can quickly guide the repair staff to trouble shooting and

repair detection of common rail. It truly become an indispensable diagnostic instrument

5) To judge whether the common rail pressure is normal based on the comparison

between the testing results and standard data.Usually indicate the below problem about

the engine if the common rail pressure is unnormal.

Engine is hard to start or could not be started.Engine lacks of power.

Engine power is not stable or some high some low.

Engine climbing powerless.

6) CR508S supports all common rail pressure sensors, including Bosch, Denso and

Delphi; measurement range includes 0MPa to 200Mpa. The accuracy is up to 0.01MPa.

Adaptive measurement mode is adopted for CR508S. User do not need to select, and

the product can automatically recognize type of connected sensors for rapid


Upgrade! CR508S Digital Common Rail Pressure Tester and Simulator

for High-Pressure Pump Engine diagnostic tool,More function.

CR508S  is  upgrade of CR508 ,more function than before ,and fixed some bugs of


Upgrade 1: Add pressure unit  "bar", CR508 only have Mpa as unit ,CR508S  has


Upgrade 2:Add pressure unit  "psi", CR508 only have Mpa as unit ,CR508S  also  has

"psi"unit,so CR508S have "bar""psi""Mpa" as unit

Upgrade 3:Add a botton ,for unit change . on the top of machine ,easy to use ,

Upgrade 4: Adjusted pressure algorithm to make measured values more accurate

Upgrade 5:  fixed some bugs of CR508
