Description
The LaMotte WaterLink® Spin Touch® Mobile (3581-AU) brings laboratory-grade water analysis to wherever the water is. It’s the same trusted Spin Touch photometer as our benchtop 3580-AU — same accuracy, same SpinDisk® technology, same 60-second results — supplied in a waterproof hard-shell carrying case with custom foam inserts so it travels safely between sites.
Using LaMotte’s patented SpinDisk™ reagent disk technology, the system automates the entire testing process. Inject less than 3 mL of sample water into a SpinDisk, insert it, and press start — the analyser handles reagent mixing, reaction timing and photometric measurement automatically, displaying results on the colour touchscreen. No chemistry training, no manual titration, no operator-to-operator variation.
With its rechargeable lithium-ion battery (approx. 150 tests per charge) and Bluetooth® connectivity, the Mobile kit is ideal for pool and spa service technicians, aquaculture farm rounds, hatchery site visits, environmental sampling runs and consultants testing across multiple locations in a day.
