The OPTISYS TUR 1050 is a turbidity measuring system with cost-efficient cuvette calibration and automated ultrasonic cleaning system. Due to its optimised cuvette measuring system, it has a very fast measuring response time and low maintenance requirements. The sensor uses the 90° scattered light method, thus the measurement optics are not directly exposed to the sample and require less maintenance. The low-range system is the most suitable system when it comes to fulfilling all the necessary regulations and requirements in water and wastewater treatment.
Product Highlights
- Rapid response time due to small measurement volume
- Simple cuvette calibration with reusable liquid calibration standards
- Integrated shut-off valve for maintenance work
- Optimal back pressure setting to avoid gas bubbles through integrated outlet valve
- Automatic ultrasonic cleaning to prevent deposits
