KASAHARA — Water-quality sensors and precision analysis solutions

KASAHARA (Kasahara Chemical Instruments Corp.) is a Japanese manufacturer specialized in water quality measurement and liquid analysis instruments, offering devices from portable testers to process-grade systems for laboratories and industrial plants. The brand is recognized for sensors and analyzers used to monitor pollution, control treatment processes and support industrial production lines. 

Product focus and technical strengths

KASAHARA’s portfolio emphasizes turbidity and suspended solids (SS/MLSS) meters, UV/COD/TOC analyzers, ion concentration meters (Cl⁻, F⁻, Ni²⁺, Cu²⁺, etc.), pH/ORP/EC/salinity meters, dissolved oxygen (DO) instruments, online SS/MLSS controllers and water samplers testing kits. These solutions serve process control in water treatment, plating, semiconductor manufacturing and environmental laboratories: 

• pH & ORP meters — bench and process models for acidity and oxidation-reduction monitoring. 

• Dissolved Oxygen (DO) instruments — for biological treatment management and aquaculture. 

• Turbidity / SS / MLSS controllers — monitoring suspended solids and sludge concentration in wastewater plants. 

• Measurement of COD, TOC, specialized ions, TMAH, fluoride, nickel, copper, ammonia… (sampling type or online). 

• Conductivity / salinity / density & concentration meters — process control for liquid concentrations. 
  

• Portable test kits and handhelds — on-site rapid checks with proven repeatability. 

Where KASAHARA brings value

KASAHARA instruments are applied to municipal and industrial water treatment, plating process monitoring, chemical and semiconductor production control, environmental testing labs and R&D. Reliable sensor data from these devices enable process automation, regulatory compliance and improved operational efficiency. 

Quality and operational fit

Products emphasize measurement stability, straightforward calibration and options for both field operation and online system integration. Specialized modules for ions, TOC/COD and MLSS permit tailored configurations to meet industry-specific measurement requirements.
