The Multi-Function Timer/Counter     

These precision instruments are for timing and counting of multiple events, and can be used in some situations where powerful computers can come up short. The new Multi-Function Timer/Counter is perfect for the laboratory setting and enables you to time and count multiple events simultaneously.

This is the device you need to measure multiple events, you were forced to connect and synchronize multiple timers and counters. It is simple to connect any or your input devices to the Multi-Function Timer/Counter and you're set. You can time and/or count multiple events - all with the same compact battery-powered device. 
But its versatility goes far beyond that. The Multi-Function Timer/Counter offers a sleep mode to conserve power when not in use and alerts you when the batteries run low. It also comes with an AC adapter. All connections are easy - either by a screw terminal or optional banana plug adapter. It's portable and far less expensive than a computer.

The Economy Timer/Counter   
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 and Tripod  
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 (not included). The pulse-modulated infrared signal is effective for up to 30’, and is not affected by surrounding light conditions. An LED indicator displays signal strength when the infrared photocell is correctly aligned with the reflector. Model 63501CBL and Model 63504 are available but are not included. Pricing for the control cable is based upon length, please specify when ordering.
