Total Energy System
5000
The electric vehicle (EV) charging market is rapidly expanding, with more and more people switching to electric cars. As the demand for EV charging stations increases, so does the amount of energy that is being exchanged. This energy exchange market is already massive, with charging peaks reaching into the megawatts of energy. With this amount of energy comes a significant amount of revenue, which requires the most accurate billing possible. That’s where TESCO’s Catalog No. 5000 – Total Energy System comes in. The Catalog No. 5000 is a double duo system that enables the testing and accuracy verification of Electric Vehicle Service Equipment (EVSE) and Field Test Equipment for testing EVSE’s in the field. This system is a dual-purpose DC and AC System and includes both a 100A AC (ACT-100) Test System and a 200A DC Test System (DCT-200).

Automatic Total Nitrogen/Phosphorus Monitoring
TPNA-500
More than 10 years have passed since the 5th Water Use Regulation was enforced in 2001. From the perspective on preservation of ambient water quality, it has become a matter of course for companies to be compliant with regulations and observe corporate compliance. Total nitrogen and total phosphorus monitoring in the future has the potential to lead to proactive enhancement of corporate value, in addition to compliance with regulations. While we propose technological innovations and improvements and LCC*1 reductions, we will pursue the future where regulations are strictly observed and corporate value is improved through monitoring.

ACCUplace Dot Distortion Target
AP-DD Series
All machine vision lenses will show some type of distortion. Minimizing or correcting that distortion is crucial in most applications. The ACCUplace Dot Distortion target is designed to detect the presence of both barrel/pincushion distortion as well as alignment distortion that causes the keystone effect. The precise amount of distortion is determined from an array of precisely placed dots in a regular array. The results can be used to correct for any distortion that occurs within the optical system. The AP-DD is offered on three standard substrates; Chrome on Glass (CG) Opal (OP) and Photo Paper (RM).
