Acrulog Differential Pressure Logger

The Acrulog™ Differential Pressure Logger is simple and compact pressure data logger for harsh environmental monitoring. The Acrulog™ differential pressure logger has been specifically designed to work in harsh environments to log levels of differential pressure in sewerage systems, and scrubbers systems.

Optional outputs: 4-20mA, RS485, 4G LTE-M or NB-IoT.

All logged data can then be easily logged and downloaded via Bluetooth® wireless technology and viewed in the custom graphing and data analysis Acrustat software.
