If a sensor goes out, both systems will give you a false reading. If you want a secondary monitor get 4 more sensors then you would have a good secondary system. **Q: all tanks are showing whatever the fresh water tank is reading. 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. ## Frequently Bought Together - RecPro Tank Sensor Monitor Panel M21 | KIB Replacement | Panel Only | Level Sensor | Fresh Water or Holding Tank Level Sensor (White) - RecPro RV Water Screw-in Tank Probe Sensors | Fresh, Gray or Black Water Tank | Made in USA | 6 Pack - RecPro Replacement Tank Wire Harness | Fresh Water | Gray Water | Waste Water Holding Tank | KIB Sensor Probe Harness (4 Harnesses) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/474689691-recpro-rv-tank-sensor-monitor-panel-m21-panel-only-white](https://www.desertcart.hk/products/474689691-recpro-rv-tank-sensor-monitor-panel-m21-panel-only-white) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-10-20*
