三協インターナショナル Company Profile

For JCSS calibration of weights and the production of custom weights, please leave everything to Sankyo International Co., Ltd.

Sankyo International Co., Ltd. is a company that handles various types of weights and calibration weights. The mass of the weights we handle ranges from 1 mg to 5000 kg. We are an MRA-compliant JCSS certified business. JCSS0345 is our certification number. Our features include high quality, low prices, and short delivery times for custom weights. We can accept orders starting from just one piece. We have a proven track record of delivering not only small mass weights but also large mass weights. For example, we have delivered large stainless steel weights such as 500 kg F2 class, 500 kg M1 class, 1000 kg F2 class, and 1000 kg M1 class. We also have delivery records for large weights equivalent to M1 class made of stainless steel, such as 230 kg and 750 kg. Among our custom weights, we have many deliveries of Newton-type additional weights. We have a wide variety of weights available, including pillow weights (made of stainless steel and cast iron), OIML-type cylindrical weights, standard weights, additional weights, and bases for additional weights. Additionally, we have a large stock of cast iron weights ranging from 50 kg to 1000 kg. Since we adjust the mass in our calibration room before delivery, you can use our products with confidence. Please feel free to contact us when you need our services.
