3.0/5
The monitored VP600, for a large well home or small business where a failed dose has to stop the water. Buy the plain VP600 if someone checks the system regularly.

Pros
- A UV sensor reads the actual dose, so a dirty sleeve or weak lamp shows up before untreated water gets through
- Can close a shutoff valve when UV falls too low
- 18 GPM at the full 40 mJ/cm² dose covers a large home or a small business
Cons
- About $500 more than the plain VP600 for the sensor and valve output
- The shutoff valve is an extra purchase
- The 31 in chamber needs a long stretch of wall plus room to pull the lamp
- A genuine S600RL-HO lamp costs about $170 on Amazon every year
- Not NSF certified

Viqua VH410M
#4 in Over 12 GPMFull review
The monitored version of Viqua’s large home unit, for well owners who want to know the dose is actually being delivered. Worth the premium over the plain VH410 if no one checks the water regularly.

#6 in Over 12 GPMFull review
A large home unit with a published Class A dose flow and a 3 year controller warranty, for less than Viqua’s monitored models. Add a sensor if no one tests the water.
