Legionella Doesn’t Wait for Your Spreadsheet to Update.
Cooling Tower Compliance — Digitized & Real-Time.
FAT FINGER digitizes your chemical dosing, sampling, and system inspections — with real-time alerts when readings go out of range.
Trusted by companies all over the world
Your Water Treatment Program. One System. Zero Blind Spots.
The Old Way Is Costing You
Dosing logs nobody trusts — Your techs write chemical feed rates and conductivity readings on paper field sheets. By the time the data makes it into a spreadsheet — if it ever does — the readings are two weeks old and the trend is invisible.
One Legionella Case Costs More Than Every Cooling Tower in Your Portfolio Combined
Learn how FAT FINGER helps water treatment teams eliminate the spreadsheet lag and give clients real-time compliance visibility.
Offline-First Architecture — Full Data Capture on Rooftops and Mechanical Rooms
Cooling towers are on rooftops. Mechanical rooms are in basements. Neither has reliable cell service. FAT FINGER captures every dosing log, every reading, every photo completely offline — and syncs the moment your tech hits signal.
Real-Time Dashboards & Alerts — Catch Out-of-Range Conditions Before They Become Outbreaks
Set threshold alerts for conductivity, pH, biocide residuals, and temperature. The moment a reading falls outside your control limits, FAT FINGER flags it — so you can respond in hours, not discover it in next month’s spreadsheet review.
Photo & Attachment Capture — Documented System Conditions at Every Visit
Photograph system conditions, chemical feed equipment, and sample collection points as part of every routine visit. When a client or health department asks “what did the tower look like on March 8th?” — you have the timestamped photo, not a memory.

Watch how teams use FAT FINGER to enforce consistent dosing logs, sampling records, and system inspections — at scale.
