透过圓盤柱塞进行壓縮測試，將產品向上擠出並圍繞圓盤邊緣。该装置可測量粘性產品的稠度，例如酸奶，面霜和調味料，加工過的水果和蔬菜，或保濕面霜，洗髮水和髮膠產品。The disc plunger performs a compression test which extrudes the product up and around the edge of the disc. This test measures the consistency of viscous products, such as yoghurt, creams and sauces, processed fruit and vegetables, or moisturising creams, shampoo and hair gel products.
