Digital Dialysate Meter™ D-4 & D-6

Digital Dialysate Meter™ D-4 & D-6

Definitive Dialysate Testing

Product Info

The DIGITAL DIALYSATE METER is specifically designed to test both acetate and bicarbonate dialysate quality. Measure Conductivity, pH and Temperature to ensure proper mixing during dialysate preparation and as a final check of dialysate quality before hemodialysis treatment. There are no strips or reagents that expire or subjective interpretation of results. Internal sensors require the user to place the sample in the instrument, preventing contamination of dialysate by the measurement device. 

  • Low maintenance
  • Easy user-friendly interface
  • Replaces up to 7 different instruments
  • Learn, Use and Train fast on only one instrument for all water testing 
  • Free live technical support with little to no wait time
  • Reliable manufacturer of the original Dialysate Meter™, Myron L® Company has served hemodialysis professionals for over 50 years

DIGITAL DIALYSATE METER will save you time and money

DIGITAL DIALYSATE METERS do not need sterilization, and you never have to return an instrument to the manufacturer for calibration.

Water and Dialysate Quality Analysis for Hemodialysis

The DIGITAL DIALYSATE METER also measures parameters critical in water quality monitoring and control at every stage of hemodialysis water treatment. Test Conductivity, Resistivity, TDS, pH, ORP, Free Chlorine Equivalent (FCE TM) and Temperature of feed and product water in unit processes. Use measurements as independent checks against automatic systems of control and to check residual levels of sanitizers in water treatment and hemodialysis systems after system maintenance.

Powerful, portable DIGITAL DIALYSATE METER features extreme accuracy in widely varying ranges, easy one-touch measurements and keypad calibration.

Bluetooth® communication available with bluDock™ option for easy record-keeping.


  • Tests up to seven aqueous parameters (depending on model): Conductivity, Resistivity, TDS, pH, ORP, Free Chlorine Equivalent (FCE TM) and Temperature
  • Factory programmed solution models for dialysate and hemodialysis water quality testing
  • Keypad calibratable
  • Autoranging conductivity/TDS/resistivity
  • Conductivity/TDS/Resistivity accuracy of ±1% of reading vs. full scale
  • pH accuracy of ±.01 pH units
  • Extremely accurate 4 electrode conductivity cell technology
  • Integrated cell cup and sensors prevents contamination
  • Full four-digit LCD display with superior resolution
  • Memory storage for 100 readings with date & time stamp
  • Real time clock
