Measure molybdate levels up to 350 ppm in boiler and condensate systems with fast, accurate Indigo® Molybdate Test Strips. Verify corrosion inhibitor balance quickly without waiting for lab results.

Molybdate-based inhibitors are widely used in industrial and institutional boiler systems to prevent corrosion and scaling in high-temperature environments. Regular monitoring ensures that inhibitor concentrations remain within optimal ranges, typically 150-300 ppm, to form stable, protective films on metal surfaces. Indigo®'s 0-350 ppm molybdate test strips deliver reliable, on-site measurements in seconds, giving plant operators immediate control over treatment dosing and blowdown schedules.

Discipline Learning Outcomes
Chemical / Process Engineering Understand the role of molybdate ions as anodic corrosion inhibitors in high-pressure boiler environments.
Mechanical / Power Plant Operations Relate chemical control to mechanical integrity; connect inhibitor balance with reduced downtime and energy efficiency.
Environmental Compliance Recognize molybdate monitoring as part of effluent control strategies and wastewater discharge permits.

Best Practices

Practice Benefit
Test molybdate levels at least twice per week. Ensures corrosion protection and dosing consistency under variable load conditions.
Correlate strip results with conductivity and pH data. Improves understanding of boiler chemistry interactions.
Maintain logs for chemical supplier review. Supports fine-tuning of inhibitor feed programs and compliance reporting.
Use fresh samples from condensate return lines. Gives representative readings unaffected by sludge or scaling.

Good product. Received product 29 Apr 26. Expiry date labeled 2028 10 14. Hopefully still good after that date. Will need to do a lot of testing to use all product before expiry date. Downside -- Shipping cost of $18.86 for item is costly. Would be nice if cheaper shipping option available. Only 3.5 stars for reasons above.

Thank you for review.  If stores properly per Stability document, strips can be used past the posted expiry of the bottle you have (2.5 years remaining).
