LaMotte Mobile Photometer WaterLink Spin Touch 3581 — Handheld Cartridge-Based, Waterproof Case

The LaMotte 3581 WaterLink Spin Touch Mobile Photometer is a handheld, cartridge-based water testing lab that runs multiple pool and spa analyses automatically from a single small sample in about 60 seconds.

The Spin Touch Mobile packs laboratory-grade photometric testing into a rugged, waterproof carry case so technicians, pool service pros, and facilities managers can perform fast, repeatable water chemistry checks on site. It uses sealed SpinDisk™ reagent cartridges that contain premeasured reagents for a full test series, eliminating reagent prep and simplifying field workflows. The system logs results and accepts calibration checks to keep readings reliable across many uses.

How exactly does the SpinDisk cartridge system simplify field testing?

SpinDisk cartridges come preloaded with the exact reagents needed for every assay, so you don't measure or mix chemicals on location. Insert one cartridge, add under 3 mL of sample, and the instrument automates the reaction and photometric reading.

• Premeasured sealed reagents prevent dosing errors and contamination
• Single-sample workflow reduces hands-on time to under a minute
• SpinDisk format supports multiple analytes from one cartridge
• Cartridges are disposable, simplifying cleanup

What results and data features does the mobile photometer offer?

The Spin Touch digitizes test results and stores them for review, helping teams track trending water quality over time. It supports calibration checks and connects via USB for data transfer and charging, enabling consistent recordkeeping.

• On-board data logging for historical comparisons
• Calibration check disk included to verify accuracy
• USB connectivity for exporting results and recharging
• Clear digital readouts reduce user interpretation error

What accessories are included and what else do I need to buy?

The unit ships ready for field deployment with a protective waterproof case and essential accessories; reagent SpinDisk cartridges are purchased separately so you select the analytes you need. The included tools help you start testing immediately.
