Hardness Tester

L.S. Starrett, Athol, MA, has introduced two new digital Rockwell/Superficial Rockwell benchtop hardness testers with fully automated load/unload procedures and capable of providing highly accurate readings. The new Starrett Hardness Tester models 3823 and 3824 utilize a closed-loop control unit with a load cell, a DC motor, and an electronic measurement and control unit instead of traditional dead weights, enabling high accuracy measurements at all test loads up to 0.5 percent.

Multi-Channel AWG

Spectrum Instrumentation, Grosshansdorf, Germany, has launched a line of arbitrary waveform generators that offer 24–48 synchronous channels in a single rack unit. Ideal for multi-channel automated testing applications, the eight different variants achieve full remote control through a simple Ethernet connection to any PC or local area network (LAN). The units feature 16 bit digital-to-analog converter technology and combine this with low-noise flexible outputs, allowing them to generate almost any test signal in the DC to 60 MHz frequency range.
