อุปกรณ์วัด Control System (pH Analog Indicator with Self Diagnostic Test)

HI 8510

pH Analog Indicator with Self Diagnostic Test

HI 8510 is ideal for monitoring pH in process control. It can provide highly accurate pH measurements and display values on the easy to read LCD. BNC input, amplified probe input and input from transmitter are supported.

Designed for easy and fast installation, the HI 8510 is provided with membrane keypads on the front panel, large display, and auto-diagnostic functions to check pH electrode and instrument status. These instruments also provide ±5V power output and input terminals for amplified electrodes.

The front panel is protected behind a transparent splash-proof cover.
