Superior reliability in low range turbidity measurement

Repeatability in low range measurement is ±1% .

Saves up to 200 data

Automatic memory at fixed time intervals is also possible and it is effective for simple monitoring etc.

• Short interval memory function: 2 sec.-99 min. 59 sec. or Long interval memory function: 2 min. 99 min. After 1 min. measurement, it will be in sleep mode.
• This sensor module does not have cleaning function. In order to maintain measurement accuracy, frequent cleaning of the sensor part is required.
• This sensor module is not for continuous measurement. When performing simple monitoring, please keep continuous use time within 24 hours.
