Digital rubber hardness tester DD5-D type
Type D durometer for general rubber (Hard hardness).It has been widely adopted in domestic and international standards, including JIS K 6253-3, JIS K 7215, ISO 48-4, and ASTM D 2240, and is now the mainstream method for measuring the hardness of various rubber products. Hardness data can be output externally using the peak hold and timer hold functions. Furthermore, by combining it with the motor-driven constant pressure load tester CLE-150 series, more precise and highly reproducible hardness measurements can be achieved.

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 holding 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 holding 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
