Depth sensor with temperature measurement HYDROS 21

The problem with most water depth, temperature, and electrical conductivity sensors (CTD sensors) is that their cost is prohibitively high. Plus they often require an extra barometric pressure sensor to correct for atmospheric pressure. You need a low-cost water level sensor equipped with everything necessary for things like tracking changes in solute movement, groundwater recharge, and surface water hydrology. You need HYDROS 21. A compact 3.4 cm diameter water level sensor that fits into tight spaces, the HYDROS 21 CTD sensor is a low-cost, durable, and easy-to-use tool for monitoring EC, temperature, and depth in both groundwater and surface water. More importantly, it's an all-in-one instrument. When used with the ZL6 data logger or any other logging system, you won't require an additional sensor for measuring -and referencing- barometric pressure. With a range of 0 to 120 dS/m and a measuring depth of 10 m, the sensor makes accurate depth and EC measurements for a broad range of applications. One of the qualities that makes the HYDROS 21 water level sensor so easy to use is its fast plug-and-play compatibility with the ZL6 data logger (also compatible with Campbell Scientific data loggers). Plus, with the ZL6, you can monitor and remotely access cloud data wirelessly from any internet-connected computer or device in near-real time.
