Overview
The Van Essen Micro-Diver is the smallest Diver capable of accurately recording groundwater levels and temperature. The Micro-Diver is specifically designed for monitoring wells or drive-points too small to accommodate larger dataloggers. In addition to its compact size, the Micro-Diver’s memory capacity can store up to 48,000 measurements per parameter - almost one measurement every ten minutes for an entire year.
Compact Pressure Sensor
The Van Essen Micro-Diver is the smallest Diver with a diameter of 18 mm and a stainless steel (316 L) casing. The Micro-Diver is suitable for pipes with a diameter of at least 20 mm (0.787 in). The Diver consists of a pressure sensor, a temperature sensor and memory for storing measurements and a battery. The Diver is an autonomous datalogger that can be programmed by the user. The Diver has a completely sealed enclosure. The communication between Divers and Laptops/field devices is based on optical communication.

 Van Essen CTD-Diver Water Level & Conductivity Logger 
 
If you need to monitor groundwater levels and saltwater intrusion, injected wastewater, or contamination from chemical discharges and landfill sites, the CTD-Diver is a good choice. It features a rugged, corrosion-proof ceramic housing and is equipped with a four-electrode conductivity sensor to measure electrical conductivity from 0 to 120 mS/cm. There are two options for measuring conductivity: true or specific conductivity at 25 degrees Celsius.

The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. 
 
Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. 
 
Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.

The Seametrics Turbo Turbidity Logger is a self-cleaning turbidity sensor capable of internally logging over 260,000 data records. The sensor enables researchers, compliance officers, and contractors to monitor turbidity in various applications, from construction and dredging sites to wastewater effluent. 
 
 Due to its narrow width, this device can be deployed in a range of areas, from small well spaces to rivers and streams. The stainless steel housing and built-in wiper allow the sensor to withstand long-term deployments and reduce the need for maintenance trips. 
 
 The logger accurately records temperature and turbidity up to a depth of 50 meters.
