Overview
The Solinst Levelogger 5 LTC combines a datalogger, 8-year battery, Hastelloy pressure sensor, temperature detector, and conductivity sensor within a small waterproof housing, 22mm x 208mm (7/8" x 8.2"). A baked-on coating using polymerization technology protects the body against corrosion, abrasion and high temperatures. The conductivity sensor is a 4-electrode platinum sensor with autoranging capabilities. The minimal-maintenance, sealed Levelogger 5 LTC is simple to clean and calibrate, even in the field.

Questions & Answers
Can the Levelogger be connected to an external data logger?
Yes, the Levelogger can be integrated with an external data logger via SDI-12 output through the use of a direct read cable and SDI-12 interface cable (PN# 115133). Please see the Accessories tab for pricing on these options.
Do Levelogger LTC loggers deployed in a well need to be pulled to the surface in order to collect data via PC?
No, a USB Interface Cable attaches to the topside connector of Leveloggers deployed with L5 Direct Read Cables, allowing for communication with a PC in the field.
Can I connect to a Levelogger LTC via Bluetooth connection?
Yes, a Solinst Levelogger App Interface (part 115009), allows Bluetooth connection of Leveloggers to Android and Apple devices.
Is the Levelogger LTC a vented pressure transducer?
No, the Solinst Levelogger LTC is an absolute logger, meaning that it is sealed from the atmosphere and records both barometric and water pressure data. Because of this, the data will need to be paired with local barometric pressure data to compensate for effects on the water level within the well. Solinst offers a vented logger, the LevelVent which can be found here: https://www.fondriest.com/solinst-levelvent-5-water-level-loggers.htm
Does the Levelogger LTC need to be calibrated for conductivity?
Yes. Solinst recommends that a conductivity calibration is performed using the Conductivity Calibration Wizard and should be done, at minimum, 2 times a year especially before initial use of the LTC Levelogger and after long periods of dry storage.

Combating Water Insecurity in Saskatchewan with Real-Time Data

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.

Seametrics Turbo Turbidity Logger: Boost your Turbidity Monitoring

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.

Collecting Data at the Top of the World: How Scientists Retrieve Glacial Ice Cores

A helicopter touches down in the small town of Sicuani, Peru, at an elevation of 11,644 feet. Earlier that day, a boxcar brought fuel, drills, food, and other equipment for a glacial expedition. The year is 1979, and glaciologist Lonnie Thompson is preparing to lead a team to the Quelccaya ice cap in hopes of becoming the first scientists to drill an ice core sample from this glacier. The only problem? The glacier is located at 19,000 feet in one of the most remote areas of the world. The helicopter takes off from the town, but the thin atmosphere at that elevation does not allow it to safely touch down on the ice– due to the aircraft’s weight, and it becomes unstable when the air is less dense.
