• For simple and safe leakage pressure testing of current air conditioning systems with the refrigerants R744 (CO2), R1234yf and R134a.
• Leak detection on A/C systems with contrast media is no longer permitted!
• KLDS 05 is introducing forming gas (N2 95 %/H2 5 %) into the A/C system, using a high performance pressure regulator. A pressure drop and thus a leak can be determined very quickly and easyly.
• The fall in pressure can be read off easily and precisely.
• The practical trolley offers enough storage space for all six test hoses, each 3.0 m long, accessories, removed parts and tools and space for safe transport of 2 gas bottles á 10 L.
• The structure of the trolley ensures a safe stand and very good maneuverability thanks to two large and high quality wheels.
• 2 safety valves (20 and 100 bar), prevents damage to the A/C system and ensure maximum user protection.
• Valve for controlled release of the test pressure.
• Knurled nut for quick and easy assembly and dismantling the pressure reducer.
• Secure HP and LP couplings for R744 (CO2), R1234yf, R134a air conditioners.
• High-quality components "Made in Germany" guarantee a safe and long-lasting use, even in harsh workshop environments.
• W 000 588 19 21 00 - Recommended by Mercedes Benz

• For simple and safe leakage pressure testing and leak localization* on current air conditioning / refrigeration systems with the refrigerants R1234yf and R134a. The testing of air conditioning systems with contrast medium is no longer permitted!
• High-precision pressure testing on the high pressure and low pressure side.
• With integrated test report printer for creating a test report.
• Documentation security through real-time clock (time and date cannot be changed)
• Leak test without contrast medium
• Leakage pressure test with nitrogen
• Leak localization* with forming gas
• * An additional electronic leak detector (ELS 04) is required to locate leaks
• Digital display, easy to read and accurate
• Measurement accuracy 0.5%
• Display 0.01 bar
• Mobile use thanks to the integrated battery
• Recorded pressure test of min. 10 minutes to max. 24 hours*

• Fast, practical, digital and documentable - this is how workshops work today!
• The compression and engine pressure loss tester DRV 05_BT* enables the recording of compression pressure values and the extended diagnosis of each individual cylinder or combustion chamber by determining the air leakage.
• By feeding compressed air into the combustion chamber in a controlled manner, the degree of leakage can be determined.
• The special device sensor enables a quick assessment. If the value is not in the green range, the measured pressure loss is not acceptable.
• Before the test is carried out, the "LR Smart Tools" app performs a guided calibration to the workshop compressed air so that the max. permissible pressure loss of the engine is set (- 23 %).
• With the DRV 05_BT* from Autotestgeräte Leitenberger, the measured values are then recorded and sent via Bluetooth® to a mobile end device, e.g. a smartphone or tablet.
• The data from the measurements can thus be analysed quickly and easily in a specially developed "LR Smart Tools" app and documented for customers.
• Advantages for the workshop
  • Measurement and immediate visualisation and evaluation ("live data" transmission).
  • Data transfer to mobile devices (e.g. smartphones, tablets etc.) via Bluetooth® technology.
  • Sharing of measurement results via PDF, e-mail, airprint, etc.
  • Graphical evaluation and saving of the measured values in a PDF document.
  • "1-man test" possible, i.e. actuate starter and read off compression or engine pressure loss measured values at the same time.
  • Range for data transmission approx. 15 m.
  • No consumables (such as pressure chart cards, paper rolls, etc.) due to the completely digital process.
  • The operation of these devices is exclusively intended within the EU. These devices are NOT approved for operation outside the EU.
  • The app "LR Smart Tools" is free of charge for all users and can be downloaded for Android and IOS in the respective stores (app for IOS from version 12, app for Android from version 8).
