Timers and Counters
The Economy Clock / Counter is a timing device that is capable of accurately recording times down to the millisecond. This device is powered by a single 1.5 volt AA battery, and a small micro is employed to provide all the operational needs of this device.
All of the switch contacts can be configured for Normally Open or Normally Closed contacts, adding versatility to the device.
This unit can display times up to 999.999 seconds before roll-over of the display occurs, and can display up to 9,999 count inputs before roll-over occurs.
The device has individually configurable inputs, it will work with contact closures, logic levels, and IR triggering systems. All the inputs are diode protected with 1N914's, whose breakdown voltage is rated at 100 Volts. We recommend a maximum rating of 30 volts DC, and absolutely no AC voltage applied to the inputs.
Infrared Control System
This battery-powered photocell is ideal for outdoor timing. It is designed to generate an infrared beam. When that beam is broken, a relay is closed and a signal starts a series of clocks or counters.
Automatic Tally Maze
The automatic tally maze attaches to a timer / counter (not included) to record errors and time required for completion.
Groove Type Steadiness Tester
This device tests dynamic steadiness. The subject is required to move a metal-tipped stylus along a narrowing channel without touching the sides.
Hole Type Steadiness Tester
The task is to hold a metal-tipped stylus in 9 progressively smaller hole sizes without touching the sides.
Two-Arm Coordination Test
This is a test of motor coordination and learning which requires both arms to work together.
Auto Scoring Mirror Tracer
This tracing device involves reversal ability, hand-eye coordination and learning. Subject is required to trace the star pattern while watching only its mirror image.
