OMRON  K3MA-F-A2  AC100-240V  Digital panel meter,,rate meter, frequency meter


This digital penel  meter Using backlight double color LED (red/green), cathode LCD display, to achieve a high degree of visibility. With the function of comparing output , comparing preset value,,according to the comparison of the output t action, can change display colors, green to  red(oppositely available )
Even thougth is  far away from the device, also can by displaying a color change,  can master operating condition of the  device easily

If don’t have the comparing output fuction, can choose the current color red or green , it  depend on the the display purpose and usage of the production site
