low flow water

In-Situ, Inc. AquaTROLL 600 MP Low Flow Kit
Multiparameter Sonde

The In-Situ Aqua TROLL 600 Low-Flow Kit contains everything you need to conduct low-flow groundwater sampling with the Aqua TROLL 600 Multiparameter Sonde. Low-Flow sampling equipment is used to direct the flow of water past the sensors of the Aqua TROLL 600 during purging and low-flow sample tests. The seal between the instrument and the flow cell prevents water oxygenation prior to analysis. The 3-way intake valve can be used to divert flow for sample collection. The anti-siphon check valve prevents back flow at the outlet. The system accommodates 3/8 in. and 1/4 in. tubing, which is not included.

In-Situ RDO Pro-X Probe
Optical Dissolved Oxygen & Temperature Sensor 

The In-Situ RDO PRO-X Probe is EPA-approved for Clean Water Act programs, using optical technology to measure dissolved oxygen and temperature in demanding process environments. The RDO PRO-X Probe lets NPDES permit holders monitor influent, effluent and treatment processes, responding quickly to oxygen and temperature changes for more accurate results.

This durable probe requires no calibration, conditioning, or membranes. The sensor cap automates setup, storing calibration coefficients, serial number, and expiration date. When cap expires, simply snap it off and pop on a new one. Integrate with telemetry systems and HydroVu Data Services for real-time feedback on all of your water monitoring sites.



  • RDO PRO-X probe (option of 10 m stripped-and-tinned cable or twist-lock connector)
  • RDO sensor cap
