HM-BCMn Portable Permanganate Index Analyzer for Surface Water Monitoring

Product Introduction

The HM-BCMn is a dedicated portable analyzer built exclusively for permanganate index (CODMn) testing — a key indicator for evaluating organic pollution in surface water, drinking water sources, and environmental monitoring programs. Following the GB/T11892-1989 national standard, it covers a detection range of 0.25–25 mg/L (segmented), making it suitable for both clean source water and moderately polluted river samples.

Unlike general-purpose multi-parameter instruments, the HM-BCMn focuses all hardware and software resources on CODMn accuracy. The dual colorimetric system accepts 16mm pre-made test tubes and cuvettes up to 50mm, while a 360° precision rotating holder ensures measurement stability. A built-in dual-zone digester heats eight vials with independent temperature control — room temperature to 200°C adjustable, reaching 165°C within 10 minutes under smart PID control at ±0.5°C.

The Android smart platform with 8-inch touchscreen (1024×768) guides operators through each CODMn workflow. Teams requiring broader multi-parameter capabilities can explore the dual-parameter COD and ammonia nitrogen platform in the same product family.
