TDS Meter (tests for purity of water)

The Digital TDS Meter is a compact, easy-to-use tool designed to measure Total Dissolved Solids (TDS) in water, giving an instant indication of water purity and mineral content. Essential for detailing, window cleaning and water filtration systems, this meter allows users to accurately assess whether their water is suitable for spot-free rinsing and professional cleaning tasks.

Simply immerse the probe into water and read the digital display. The TDS Meter instantly shows dissolved solids levels, helping you determine water hardness and identify when DI resin, RO membranes or filtration systems are no longer performing effectively.

Portable and reliable, this tool removes guesswork from water quality management and helps reduce wasted resin, poor cleaning results and unexpected water spotting.

Key Features:

• Measures Total Dissolved Solids in water
• Instant digital readout
• Simple dip-and-read operation
• Compact and lightweight design
• Ideal for monitoring DI and RO filtration systems
• Helps identify hard, soft and ultra-pure water
• Battery powered and portable
  

Technical Information:

• Measurement Type: Total Dissolved Solids
• Display: Digital LCD screen
• Operation: Manual dip test
• Use: Water quality testing and filtration monitoring
• Portability: Pocket-sized design
• Power: Battery operated

Applications:

• Monitoring de-ionised water systems
• Checking resin exhaustion in DI filters
• Reverse osmosis water testing
• Window cleaning and water-fed pole systems
• Car detailing final rinse stages
• Solar panel cleaning
• General water quality assessment

Benefits:

• Confirms when water is suitable for spot-free cleaning
• Indicates when DI resin or filters need replacing
• Prevents water spotting and streaking
• Helps maximise filter and resin lifespan
• Saves money by avoiding premature filter changes
• Essential diagnostic tool for professional cleaners
• Water Hardness Guidance:

Use TDS readings alongside local hardness levels to assess filtration needs.

Water Hardness	mg/L CaCO₃
Soft	Up to 100
Slightly Hard	100 – 150
Moderately Hard	150 – 200
Hard	200 – 300
Very Hard	300 +

Higher hardness levels will exhaust DI resin more quickly.

HQ Suggests (Tips & Insights):

💡 Always test your tap water first to understand local hardness before installing filtration.
💡 Check DI or RO output regularly to catch resin exhaustion early.
💡 Spot-free rinsing typically requires near-zero TDS readings.
💡 Rising TDS levels are the clearest sign it is time to change resin or filters.
💡 Ideal tool to keep in mobile vans for quick on-site water checks.
💡 Store dry and clean between uses to maintain reading accuracy.
