The MIRO PQ21 builds on the proven PQ20 platform and adds a dedicated current channel, allowing you to monitor load current or return current alongside voltage quality measurements. This makes it ideal for SWER line monitoring, rural feeders, and single phase installations where both voltage compliance and power performance need to be assessed.
In addition to voltage (Phase–Neutral and Ground–Neutral), THD, harmonics, flicker and mains signalling capture, the PQ21 enables real power monitoring by logging current and calculating power parameters. Compact, IP66 rated and easy to deploy, it simply plugs into a wall outlet (or can be connected directly to panels), with Wi-Fi access and reporting via the CITRUS software platform.
Designed and manufactured in Australia, the MIRO PQ21 is a practical solution for utilities, electricians and engineers requiring reliable single phase power and voltage logging in the field.
The MIRO PQ21 is a practical and versatile single-phase power quality logger that combines voltage and current monitoring in one compact unit. In addition to measuring Phase Neutral and Ground Neutral voltage, it includes a dedicated current channel, allowing you to monitor load current or return current at the same time. This makes it particularly well suited for SWER line monitoring, rural feeders, and single phase installations where understanding both voltage compliance and actual load behaviour is important.
The PQ21 captures key voltage quality parameters including RMS voltage, THD, individual harmonics, flicker and mains signalling (ripple control), while also enabling power and energy calculations such as real power, apparent power and power factor. Housed in a rugged IP66 enclosure, it is designed for field use and can be deployed quickly using the fixed voltage lead or connected directly to panels where required. Built in Wi-Fi provides easy access for configuration, real-time viewing and data download through the CITRUS software platform, which supports detailed analysis and professional reporting.
With gapless logging, 8GB internal memory and an internal backup battery to ride through short interruptions, the MIRO PQ21 delivers reliable long term monitoring. Designed and manufactured in Australia, it offers dependable performance and direct local support for utilities, engineers and electricians working in both urban and remote environments.
