You can connect up to four probes to a single CHESTER device for indirect AC and DC measurements.
Measurement range according to application needs
Connect current probes with the maximum current range to suit your project needs. For example, 0-10A, 0-50A, 0-100A, 0-300A or 0-1000A.
Battery-friendly wireless connectivity
The device transfers data over cellular networks (NB-IoT / LTE-M) or public/private LoRaWAN networks.
Fast deployment and seamless integration
Use the HARDWARIO Manager iOS/Android app to set the device and integrate its data from HARDWARIO Cloud.
