ASKER DD5 TYPE A dùng cho cao su tổng hợp (độ cứng trung bình), được áp dụng rộng rãi trong các tiêu chuẩn trong nước và quốc tế như JIS K 6253-3, JIS K 7215, ISO 48-4 và ASTM D 2240, và là phương pháp chính để đo độ cứng của các sản phẩm cao su khác nhau. Dữ liệu độ cứng có thể được xuất ra bên ngoài bằng cách sử dụng các chức năng giữ đỉnh và giữ thời gian.
ASKER Japan
Digital rubber hardness tester
Model : DD5-A type
Features ASKER DD5 TYPE A
■ Indenter
The shape of the indenter is a truncated cone with a height of 2.50 mm.
■ Minimum reading value
The minimum reading is 0.1 points.
■Peak hold function
The peak hold function makes it easy to read the maximum value, and is particularly useful for accurately measuring the hardness of samples where stress relaxation occurs (the reading drops immediately after pressure is applied).
■ Timer hold function
The timer hold function allows you to hold the measured value for any time between 1 and 15 seconds.
Peak hold value and timer hold value can be obtained simultaneously with one measurement.
■ Interface box
Communication with external devices such as PCs is possible by connecting via USB or RS-232C. *Selectable
