FreshWater Smart Monitoring Sensor For Spas

The FreshWater Smart Monitoring Sensor provides hourly water testing for spa water, focusing on keeping the experience natural-feeling and clean. It’s designed to minimize manual checks, automatically tracking pH, chlorine, and salt levels. This sensor supports continuous monitoring, reducing guesswork and enabling proactive adjustments for spa maintenance. The device aims to simplify routine care so users can relax rather than measure constantly.
Lupo 3-in-1 Pool Test Kit

This 3-in-1 test kit covers total chlorine, total bromine, and pH for residential pools and spas, compatible with fresh and saltwater systems. It uses a simple comparator and reagents to yield results quickly, with easy-to-follow pictograms for non-technical users. Engineered to industry standards, it helps homeowners monitor essential parameters to maintain clean, balanced water without specialized equipment.
EASYTEST 7-Way Pool Test Strips

The EASYTEST 7-Way Strips provide seven essential measurements in one strip: bromine, total alkalinity, pH, free chlorine, total hardness, cyanuric acid, and total chlorine. They come in a pack of 150 strips, delivering cost-effective, rapid readings that help keep pools and spas safe. Simply dip the strip, compare to the color chart, and interpret the results for quick adjustments.
ITS 486201 Pool Exact EZ Photometer

The ITS 486201 Pool Exact EZ Photometer uses a digital readout to eliminate color matching, delivering precise test results with reagents bundled in the kit. It covers multiple parameters including total alkalinity, cyanuric acid, free and total chlorine, phosphate, calcium hardness, pH, and chloride, along with an entry kit that includes reagents and a cleaning brush. This setup suits discerning pool owners who want accurate lab-like results at home.
New Digital Pool Water Tester & Smart Monitor

This modern digital monitor measures chlorine, pH, salinity, ORP, EC, TDS, and temperature, offering 24/7 pool monitoring for hot tubs, ponds, and spas. Real-time data is accessible via a companion app with live tracking, data logging, and instant alerts. Its patented optical and flow sensors deliver more reliable results than test strips, supporting proactive maintenance and balanced water in a connected, smart-home environment.
Troxlly Salt Water Pool Chlorinator System

The Salt Water Pool Chlorinator System uses a USA titanium cell and a self-cleaning function to automate chlorine generation for pools up to 15,000 gallons. The design prioritizes easy installation and operation, delivering significant chlorine cost savings through electrolysis of brine. It provides a highly automated solution that reduces routine chemical adjustments while maintaining consistent sanitizer levels.
Buying Guide
- Water testing method: Choose between test strips, liquid reagents, or digital/photometer-based systems. Strips are inexpensive and fast; digital options offer higher precision and trend data.
- Maintenance goals: If you want minimal manual testing, consider smart sensors or automatic chlorination systems that balance water automatically.
- Pool type and size: Ensure compatibility with your pool volume (e.g., up to 15,000 gallons for some salt systems) and water type (fresh vs saltwater).
- App and data features: For smart monitors, verify app reliability, data logging, remote alerts, and ease of integration with existing home systems.
- Installation requirements: Some systems require professional setup; others offer plug-and-play installation. Check for wiring, electrical, and safety considerations.
- Long-term costs: Evaluate reagent and replacement parts, maintenance frequency, and energy usage for automated solutions.
- Safety and compliance: Ensure devices meet local safety standards and provide clear instructions for safe operation around pools and spas.
