Joman Product Lineup

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.

Hardness can be measured by pressing three types of indenters against the material being tested. The corresponding materials for each type of indenter 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. It features a hold function and zero adjustment.
