Domestic multi parameter water quality analyzer company

ST-L908Multi parameter online water quality analyzerCan simultaneously measure: conductivity (electrode type) PH、 Six parameters: temperature, residual chlorine (imported electrode), turbidity, and dissolved oxygen. Each channel is independent of each other, without switching switches, and does not interfere with each other.

1. Measurement range: 0-200ug/L, 0-20mg/L, with automatic range switching.

2. Temperature: -10~130 ℃

3. Resolution: 0.1ug/L, 0.01mg/L at 0.1 ℃

4. Accuracy: ug/L: ± 1.0% FS; mg/L: ± 0.5% FS, ± 0.3 ℃

5. Temperature compensation: Automatic (± 10 ℃ offset adjustment) Manual (calibration temperature can be set)

6、 Each channel is independent of each other, and the data of each channel is measured simultaneously.

7、 Conductivity pH、 Temperature, residual chlorine, and turbidity are displayed on the same screen.

8、 Current isolation output: independent 4-20 mA for each parameter (load<750>)
