Meter Test Stand
Fast and Accurate Meter Verification at the Field or Lab
Utility companies and meter manufacturers need efficient tools to verify meter performance during installation or production.
Tespro’s MTS-P test stand offered accurate testing for both single-phase and three-phase meters. With voltage indicators, overload protection, and a compact design, it was easy to deploy on-site or in labs.
❓ Why it fits:
✅ Simplifies the testing process, ensures measurement integrity, and supports various meter configurations.
Calibrator
Portable Calibration Tool with Lab-Grade Precision
In-the-field calibration traditionally required bulky instruments and long setup times.
The TA-272-3P is Tespro’s lightweight three-phase calibrator, supporting 10–660V input, harmonic analysis, CT/PT ratio testing, and Bluetooth/Wi-Fi for wireless transmission. Built for grid companies and calibration agencies.
❓ Why it fits:
✅ Combines portability with high precision. One tool replaces multiple bulky devices in field calibration tasks.
