✽ Beyond Conventional Testing
How DIT31 Stands Apart
The DIT31 introduces a proprietary testing method that no other system offers:
🔹 Tests each injector individually
Maximum accuracy for every single component.
Each injector is validated independently, without external influence. This makes it easy to detect defects or irregularities right away, reducing the risk of replacing parts that are still in good condition.
🔹 Delivers reliable and repeatable data
Same injector, same results – every time.
Thanks to our proprietary technology, results are consistent regardless of the operator. This eliminates the uncertainty of traditional benches and gives end customers the confidence of objective, professional testing.
🔹 Provides injection-by-injection analysis
A unique level of detail on the market.
DIT31 is the only system that measures and records every single spray event, instead of just aggregate values.
👉 No competitor delivers this level of precision and speed.
