Turbidity sensor

Turbidity

Greenspan’s turbidity sensor reliably measures the turbidity of a body of water. To match your research and monitoring requirements we offer two series of turbidity sensors.

Turbidity is an important water quality measurement to monitor as both plant and animal growth depend on turbidity levels. Greenspan’s turbidity sensor measures the optical features of a liquid and measures its clarity by determining scattered light levels within the column of water.

The robust acetal bodys and sensors allow for delpoyment in acidic or salty active waters. As the sensor is self cleaning they can operate in marine applications and waterways with high sediment loads.

Can be installed in active waters (acidic or hypersaline) where stainless steel is not suitable
Our reliable and robust sensors ensure minimal field visits for maintenance
Suitable for marine applications and waterways with high sediment loads
Turbidity measurement conforms to ISO7027
Integral self-cleaning wiper
Rugged acetal body
Field replaceable wiper pad or actuated sensor cap

Serial or Analogue Ouput?

The TS-1000 series can have either an analogue output (TS-1000A) or an integrated logger with serial output (TS-1000L).

TS-1000A analogue sensors have a 4-20mA output (V output is possible upon request).

TS-1000L logging sensors have either RS-232, RS-485, or SDI-12 when the SDI-12 adaptor is connected.

Australian Made

Greenspan has made our range of water quality sensors in Australia for over two decades. Our experience has allowed us to design sensors that reliably deliver accurate data in the harshest environments Australia has to offer.

With every Greenspan water quality sensor, you receive; local support from our experienced sales and service technicians, local repairs and recalibration from our Melbourne-based engineers, and access to local spares from our factory in Melbourne. No other brand of water quality sensor can offer such exceptional service.
