DPS1 Hach pHD sc Online Process pH Sensor – General Purpose Stainless Steel pH Sensor

Cảm biến pH vi sai với Encapsulated Preamp:
Sử dụng ba điện cực so với hai điện cực truyền thống giúp tăng độ chính xác trong đầu dò pH kỹ thuật số này.
Tuổi thọ cảm biến pH mở rộng:
Cầu muối có thể thay thế giữ lượng chất đệm cao hơn giúp kéo dài tuổi thọ của cảm biến pH và bảo vệ điện cực.
Tùy chọn gắn kết linh hoạt:
Cảm biến pH có sẵn trong bốn kiểu lắp – chuyển đổi (convertible), lắp (insertion), ngâm (immersion) và vệ sinh (sanitary) để theo dõi pH trong thời gian thực.
