DO measurement is possible even without flow rate! A portable fluorescent oxygen meter unaffected by interfering substances.
The DOP-01 is a compact, portable fluorescent oxygen meter that allows for immediate DO measurement. It can measure in environments where stirring is difficult and there is no flow, as there is no self-consumption of oxygen. There is almost no measurement error due to influences such as hydrogen sulfide or pH fluctuations. Additionally, since it does not use electrolytes or lead, there is no concern about the leakage of harmful substances due to membrane damage. 【Features】 ■ Portable ■ Long-term no maintenance ■ No flow required ■ No influence from interfering substances ■ Safe and hygienic design *For more details, please refer to the catalog or feel free to contact us.
