Production counters:

You can connect our production counters to your PLC, or your MIS system, or just add a sensor to it to automatically count a variety of materials that range from boxes and bottles, to transparent material and metals, and any other materials that you need, we are able to find a sensor for you.


Traffic counters:

Add an IR sensor or Pad sensor to count traffic in your manufacturing facility, store, mall, or anywhere you would like to measure traffic. If you want to see how many times an operator needs to leave the station, add a pad sensor counter.



We have standard timers or special timers that include:

Event Timers:

Our easy to install digital clocks can help every company reach their goals by helping highlight wasted time. Call us today and speak with our process expert to see how digital times, clocks, and production counters can help you boost efficiency.

Oh, and if you want to implement a lean manufacturing process, give us a call to see how we can help you make it happen even faster. Most of our customers buy one unit and implement it in one of their manufacturing lines, and then order more to get these low hanging fruits. These units include Quality boards, Safety boards, Productivity boards and of course, Digital time clocks.



What is the main function of a clock? Of course, the answer is to tell the time. Our NTP (Network Time Protocol) clocks are accurate to +/- 100 milliseconds while our GPS clocks are even more precise by being accurate to +/- 1 microsecond. Also, our stand-alone clocks can be adjusted to achieve +/- 1-second accuracy.



We have built thousands of projects that are one-of-a-kind for our customers. If you have a specific need, we can help you achieve that goal. From adding sensors to our displays, to achieving a specific functionality, we can help. A few examples of this is if you have a critical process that you would like to complete in a certain amount of time and our automated timers can kick and alert your management if the process takes too long. This ranges from a bottleneck in your process to an employee that went into a hazard zone. All these can help you mitigate risk or to get the attention you need to monitor a critical process by adding visual and audio alerts, all is possible with our tech team.
