Turbidity Logging Sensor TS-1000L

The TS-1000L sensor provides a complete self-contained Turbidity measurement and data logging system for a wide range of environmental water monitoring applications. For a non-logging version with analogue output see Greenspan’s TS-1000A.

The Greenspan TS-1000A is a turbidity sensor whose features include:
  • Can be installed in active waters (acidic or salty) where stainless steel is not suitable
  • Reliable and robust sensor ensures 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
  • Easy to use


TS-1000L – Logging Turbidity Sensor

Turbidity is an optical feature of a liquid and a measurement of its clarity, a turbidity sensor is used to measure clarity. Determining scattered light levels within a column of water indicates turbidity. It is an important measurement to take in assessing the quality of a body of water as both plant and animal growth depend on turbidity levels.

The Greenspan TS-1000A logging turbidity sensor is a low-power unit with an integrated logger. The sensor features an integral wiper, providing long-term reliable operation at remote sites where bio-fouling or sedimentation is likely.

A durable acetal body and double O-ring design ensure suitability for harsh environment applications. The TS-1000A turbidity sensor can be supplied in various ranges and comes fitted with a molded polyurethane cable.
