Remote Display Sample Leads

I need a pair of all weather outdoor remote displays for our current truck scale (Mettler-Todedo, Single Axle Scale application). The old units were damaged in a lightning storm after nearly 6 years of use and cannot be repaired.

I am looking for a remote display unit for a fairbanks intalogix scale 2500 series. Our scale has a DB9 jack at the back that can output a 4-20mA signal.

I am looking for three low cost outdoor remote displays suitable for a truck scale. Digit height 3" to 5" Cost ideally under $1,000 each.
