Process Instruments (Pi) are based in Burnley in the United Kingdom, with subsidiaries in Ireland & France and a company representative in China.
Pi has two models of controller/analyser, the CRIUS 4.0 and the CRONOS. CRIUS 4.0 offers more sensor connections and more functionality/flexibility with a colour screen, optional GPRS modem or LAN adaptor so results can be monitored anywhere in the world.
Highest Quality – Low Cost – Superior Functionality
KEY Benefit :
The CRIUS 4.0 controller provides users with numerous benefits such as:
- Up to 8 sensors with appropriate analogue outputs & relays, and the option for further expansion.
- Onboard PID and other controls.
- Onboard data logging.
- Remote Access via MQTT.
- Industry leading autocleaning options for sensors.
CRIUS 4.0 are successfully used in different water treatment processes such as drinking water, municipal waste, swimming pools etc.
