Purcheck-2-3-8 Inline DI Monitor
Real-time deionization monitoring with integrated 3/8" John Guest push-fit tee for inline TDS measurement
Live monitoring catches exhausted resin before your water quality drops
Continuous TDS Reading
Monitor deionized water quality in real time to catch resin exhaustion before you ever send impure water through your application
Push-Fit Integration
Built-in 3/8" John Guest tee installs directly into your DI line without cutting or threading, maintaining full flow while sampling conductivity
Instant Alert System
Digital display shows when your mixed bed or polishing resin needs regeneration or replacement, eliminating guesswork from DI maintenance schedules
Low Flow Disruption
Tee design samples a small portion of flow for measurement while maintaining pressure and flow rate through your main line
Works with standard 3/8" tubing systems
The Purcheck-2-3-8 monitor fits any deionization system using 3/8" OD tubing with John Guest push-fit connections. Common applications include polishing DI stages after RO systems, laboratory water purification, spot-free rinse systems, and aquarium reef systems. Install downstream of your DI cartridge or resin tank to measure output quality. Compatible with Good Water Warehouse DI systems, mixed bed cartridges, and any standard deionization setup using 3/8" quick-connect tubing.
Calibration and probe care
Probe Inspection
Check conductivity probe for mineral deposits or buildup. Wipe clean with soft cloth if needed to maintain accurate readings
Calibration Check
Verify monitor accuracy against known TDS solution or reference meter. Recalibrate according to manufacturer instructions if readings drift
Battery Replacement
Replace batteries when low battery indicator appears to maintain continuous monitoring capability
Protect Your Process
Catch resin exhaustion before compromised water reaches equipment or final rinse applications
Optimize Resin Life
Replace DI cartridges based on actual performance data instead of arbitrary schedules or guesswork
Tool-Free Install
John Guest push-fit tee connects in seconds without tools, cutting, or thread tape
Quality Documentation
Digital readout provides verifiable proof of water purity for quality control and compliance records
