Hardness Testers

TEMP-4к - Portable dynamic hardness tester with the built-in transducer

Hardness TEMP-4КWireless hardness tester ТEМP-4к on functionality represents one of updating widely used in the industry serial electronic portable hardness tester ТEМP-4 and allows to work in winter conditions (to-30°S), at the raised temperatures (to +70°С), and also in the conditions of insufficient light exposure thanks to adjustable brightness. The device is intended for express measurement of hardness in various products (from a steel, pig-iron, nonferrous metals, rubber, other materials) in industrial and laboratory conditions on scales of Brinell (НВ), Rockwell (HRC), Vickers (HV), Shore "D" (HSD). Also they can measure strength of steels on stretching Rm according to GOST 22761-77.
Built in the case wireless hardness tester the semi-automatic transducer with the big resource of work has replaceable nozzles, including extended (fig. see diameter 5 mm, length 50 mm), also allow to work as one hand in any spatial position. By means of the extended nozzle, wireless hardness tester allows to spend measurements in remote zones (on gear wheels - on tooth top, on a working surface and in hollows, pulleys, at platens of welded butt and angular seams). Absence of a connecting cable raises reliability hardness tester and stability to adverse influences of an environment.
