TLT 3000/5000


The NLT-123AC type differential pressure air leak tester presented by NIPPOH incorporates an improved differential sensor performance and smaller size.

A bi-color LCD, similar to conventional models, has been adopted to improve information visibility.
An appealing price has been realized with further cost reductions.
Consider incorporating this air leak tester in your systems.


Either electro-pneumatic regulator (E) or manual regulator (R) is indicated after the model.
