• Test kits for boiler waters and applications requiring trace levels of D.O. (ppb range) employ the Rhodazine D methodology
• Rhodazine D compound in reduced form reacts with dissolved oxygen to form a bright pink reaction product
• Method is not subject to salinity or dissolved gas interferences
• Oxidizing agents, including benzoquinone, can cause high results
• Reducing agents such as hydrazine and sulfite do not interfere
• Results are expressed as ppm (mg/L) or ppb (g/L) O₂

• Plastic case
• Refill Reagents for 30 tests
• Comparator
• Adhesive mounting clamp
• Permanent mounting clamp
