We offer two types of displays. The standard display is a six digit counter that works fine for most applications when mounted in a clean dry location. We also off a sealed counter at slightly higher cost. Meters ordered with 0.1 kwh resolution will be shipped with a counter with one red wheel and the others either black or white. The counters for California meters are sealed and have seven digits with two red wheels. If you select None, you will need to provide your own counter or use it in a system where the meters are read by computer.
The numbers on the right side of the drop down box indicate the number of digits on each side of the decimal point. 5.1 means a six digit counter with one red wheel. 6.0 means all the wheels are the same color.
A limited number of sealed, six volt counters with one red wheel are available for installations where the counter must be installed a long way from the meter. Contact the factory directly.
