Hardness can be measured by pressing three types of indenters against the material being tested. The corresponding materials for each indenter type vary. Type A (truncated cone) is suitable for plastics and rubber, Type C (spherical) is for expanded polystyrene and sponge, and Type D (conical) is for hard rubber and flooring. The material being measured must be at least 6mm thick. There is a hold function and zero adjustment available.

Features: This is a portable multi-gas detector that can simultaneously and continuously detect four types of gases: O2, LEL (flammable gas), CO, and H2S. The concentration measurements of each gas are displayed on an LCD. This detector allows for the setting of low/high concentration alarm settings and STEL/TWA alarm functions. If the pre-set alarm settings are exceeded, it warns the user with audio, visual, and vibration alarms.
