What Our Customers Say
Discover what makes THOMLER special.
The app notifications caught an imbalance I would've completely missed.
Finally understand what's actually happening in my hot tub water.
Takes the guesswork out of pool maintenance. Instead of messing with color charts and reagent bottles, I just dip the probe and check the display. The smartphone alerts keep me from letting things slip.
Been using this for two months now and honestly prefer it to calling in a service technician every other week. The thermal compensation means I get consistent results whether I test at sunrise or afternoon.
The portability is what sold me—I can grab it when I'm heading to the pool house and it's light enough I don't think twice about carrying it. Battery life has been solid, and the app's trend tracking helps me see patterns in my water chemistry over time.
