demo kit是英文人明白的，間單寫
Demo kit is available
或
We have demo kit.
問題反而是你所說的「歡迎"參考"」的意思是甚麼：
?你們會送出demo kit給對方(假如對方要) = We will send you a demo kit upon request. [你只要開口要，我們自動送出]
?你們的demo kit是在你們公司/工廠裏的，客戶可以來試用 = We have demo kit available to testing in our office/company/factory.
?你們的demo kit可以為讓每個客戶認購一套 = Demo kit can be order for $$XXX per customer.
當然還有其他可能的"參考"方式，所以要看你們的國貿意思了。

We are now doing function of using our goods as demonstrating purposes in the Pacific Mall and any customers interested please do come that show. Thank you. Yip
