TX10 pH/ORP Transmitter, 4-20mA, 110-220V AC, 1/8 Din by Sensorex

The TX10 and TX20 transmitter series offers a cost-effective, small footprint solution for pH and ORP process control. Save space in your panel with either of these 1/8 DIN size models. The simple and easy to understand user interface features a four button membrane keypad for quick set up and programming. The TX10 has an isolated, reversible 4-20mA current output, providing versatility for a wide range of process control applications. The TX20 features two sets of programmable on/off relays, allowing the device to control warning lights, alarms or other process control systems. Both models feature a large, clear LCD panel display for quick and easy reference to pH, or ORP, or temperature.
