This new and advanced model of digital concrete hammer microprocessor operated consists of the standard unit similar to the model HT225-A but equipped with an electronic transducer which converts the rebound of the hammer into an electric signal and displays it in the selected stress unit. The digital hammer, which is battery operated, can be easily connected to a PC or serial printer via the RS 232 port. A large permanent memory can store up to 48000 results. Supplied complete with battery charger and serial cable.
