194Q is a high-end multifunction power analyzer manufactured by Blue Jay. higher measurement accuracy and powerful functions. With its four direct access keys and TFT displays friendly full text interface helps user operate device more easy in 3P3W or 3P4W LV installation. All monitored data is available via a digital RS485 communication port running Modbus Protocol.

It can be used as a data gathering device for an intelligent Power Distribution System or Plant Automation System. Provide Harmonic measurement with multi-tariff record user can easy establish accounting standards for different time. Max 52th harmonic individual monitor let user clear grasp of the present electrical grid quality.
