RCCB Demo
RCCB DemoThis apparatus is a companion to the Circuit Breaker Demonstration LA10-170A
It shows all the working parts of a modern RCCB type fuse as used in domestic consumer units. The apparatus is contained within a robust plastic tray with protective acrylic cover and includes a clear circuit layout on the main panel.
Reaction Timer
Reaction TimerFor use with Lascells timers. The subject presses the START button and after a short random delay the light comes on. The subject has to press the button as quickly as they can in response. The timer records the interval between the light coming on and the button being pressed. No power supply required.
Rechargeable Balance
Rechargeable BalanceSturdy construction and easy operation deliver reliable weighing. Uses a standard rechargeable battery that can be charged with a USB cable.
