We are repair and servicing Welltronix RPM Counter (PC100) units with precision. Our engineers carefully inspect the PCB and circuitry to detect component failures and measurement errors. Faulty elements are replaced using quality-tested spares, followed by calibration and performance testing. The counter is verified for stable readings under actual conditions. If you want to repair such modules, we can provide the service. We are not the manufacturer – we only provide repair services.
