Might replacing this monitor fix that problem?** A: All is reading if there is problem for frish cheack sensore **Q: Im confused. Does this come with the sensors to put onto/ into the tank? Or do i have to buy those separate?** A: It does not come with the sensors. It has the standard hook-ups that snap onto the sensor ends. My tank came with the sensors in it. **Q: what sensors work best with this ?** A: Kib manufacturers the sensor packs. The probes aren’t super important. ## Customer Reviews ### ⭐⭐⭐⭐ Review *by B***R on 10 January 2022* سعر جدا مناسب ### ⭐⭐⭐⭐⭐ Review *by J***! on 11 March 2026* Perfect replacement for our Lakota horse trailer with living quarters.
