Information regarding Discontinued Models

Please note that the models described below have ceased being produced. We thank you for your continued patronage of the products.

We used the utmost effort to obtain the necessary parts so that the models could be used as long as possible, however, it became impossible to obtain both parts and consumables for the models, resulting in it being extremely difficult to provide repair and maintenance services. We apologize in advance to any customers still using any of those models for any inconvenience caused by their discontinuance and appreciate your understanding.

In place of the discontinued models we have released new models (excluding oil content meter). We would be grateful if our customers would consider renewing the relevant equipment. Please feel free to contact us if you have any questions.
