Shodex ri201h has many improvements that make it fast and stable. By using a microprocessor, the process from solution replacement to baseline stability check can be carried out automatically.

1. Dual temperature control greatly reduces the drift caused by the fluctuation of ambient temperature, and the machine is stable and fast.

2. Wide refractive index range, low noise and stable operation.

3. The light quantitative automatic regulator can automatically compensate the sensitivity drop caused by pool pollution or other reasons.

4. High resolution automatic zero return function controlled by microprocessor, output signal drift adjustment function and key operated reference pool cleaning function can make the operation simple and rapid.

5. Anti internal leakage design, once the solvent leakage occurs, the pump can be stopped automatically, which can keep the internal electronic and optical elements dry.
