OTA Two-Wire RS485 Interface Laser Turbidity Meter For Waterworks


Turbidity controller is a device which designed to be permanently installed as either a stand alone instrument, or as part of a control panel. Can offer continuous turbidity measurements from a Turbidity Sensor.


The turbidity controllers are supplied with a number of set-points for control purposes, which can work directly with control equipment such as valves and pumps. The control set-points and corresponding relays can be used to close a valve or stop a process should the turbidity value be out of specification. In addition - an alarm relay can be used to alert an operator to the turbidity being out of specification.

Q1. What are the advantages of a digital turbidity meter?

A: The digital universal controller is matched with the corresponding digital sensor for detecting. Compared with the traditional instrument and sensor combination, the biggest advantage is that the data transmitted from the sensor to the controller is more stable and accurate, the application is flexible, and the use is more convenient.


Q2. How does this turbidity controller collect data?

A: This digital turbidity meter is a single-parameter universal controller. Each controller will be pre-installed with a set of embedded software to correspond to different sensors. These connected sensors upload the detected data with a special encrypted communication method to ensure that the controller can collect high-precision data more stably. The controller will display the collected data on the display screen in real time, which is convenient for users to read.


Q3. Does the conductivity controller operation interface support customization?
Yes, our conductivity controller operation interface can be tailored to customers' needs.


Q4.Can customer's logo be added to the controller system and cover?
Of course, we support OEM services for customers. Both the boot interface and the controller shell can be added to the customer's logo, but there is a minimum order quantity requirement.


Q5.How long is the warranty period?
The company guarantees the instrument for one year (12 months) from the date of shippment, and the consumables and wearing parts in the equipment are not covered by the warranty.


Q6. Does the turbidity controller have an ambient temperature alarm function?
Our Turbidity controller has ambient temperature alarm function.


Q7: What is your shipping method?
A: Small orders are delivered by international express, Bulk orders are recommended to ship by sea.

Q8: The turbidity controller with OTA function?

Yes. Our DUC2-LTU-S-A turbidity controller Default with WIFI.
