Wallace menawarkan Durometer Genggam (Handheld) baik dalam bentuk analog maupun digital (termasuk Shore A, Shore D, dan Shore OO). Durometer ini memungkinkan hasil yang akurat dan dapat diulang sesuai dengan standar yang relevan. Semua model dirancang untuk aplikasi genggam atau digunakan bersamaan dengan Wallace Handheld Durometer Stand (WAH18).
Durometer Genggam Wallace dirancang untuk mengukur kekerasan berbagai material. Cukup dengan menekan unit secara vertikal pada sampel, indenter akan menembus sampel dengan gaya pegas tertentu. Kedalaman indentasi diubah menjadi nilai kekerasan.
Untuk meningkatkan keulangan dan akurasi, gunakan unit genggam ini bersama dengan stand H18. Hal ini akan memastikan bahwa gaya dan kevertikalitas yang konsisten dipertahankan, sehingga meningkatkan keulangan dan akurasi setiap pengujian.
