The New Model 392 is designed to provide the latest in recorder technology with an all new servo motor drive system. It's from the leading manufacturer of microprocessor-based circular chart recorders with over 20,000 in operation worldwide.

The Model 392¡¯s design and solid construction makes field upgrades and the addition of features and maintenance quick, easy and affordable.

Individually programmable, the recorder can be quickly and easily configured to your exact application using the integral keyboard and display.

Much more than a recorder, the Model 392 puts you in control with two available 3-mode PID controllers with features such as cascade or ratio/bias, feed forward and internal setpoint generators available. Dedicated auto/manual and remote/local setpoint keypads allow the operator to switch easily between control modes.
