pH/ORP Controller with Tele-Control and Sensor Check Model Hi 504

pH/ORP Controller with Tele-Control and Sensor Check

Model HI 504

HANNA Instruments® introduces the innovative, new HI 504 series. This series offers elevated performance, rugged design and Tele-controlTM technology for users on the go. This technology supplies the means to control one or more installations from any distance - and in real time. Tele-control technology creates the opportunity to optimize operations such as maintenance cycles and reduces unscheduled and costly plant shutdowns. Operators can also control the complete regulation process by the RS 485 output and HANNA s Windows® compatible software (optional). Measurement reliability is guaranteed by self-diagnostic and troubleshooting functions.

With a host of configurations, the HI 504 series is designed to fit your individual needs. The HI 504 series in conjunction with HANNA s industrial pH& ORP probes is a powerful and efficient solution to industrial optimization.
