The LTC Levelogger Junior
logs conductivity, as well as water level and temperature. Like the LT Levelogger Junior, it is easy to transport, program, deploy and retrieve data. It combines a datalogger, 5-year battery, pressure transducer, and temperature and conductivity sensors within a small waterproof housing, 7/8' x 7.5' (22 mm x 190 mm).
The conductivity sensor is a 4-electrode platinum sensor, with auto-ranging capabilities. The minimal maintenance, sealed LTC Levelogger Junior is simple to clean and calibrate,
even in the field.
Using standard Levelogger Software, it displays conductivity, temperature, and temperature-compensated water level. Memory is non-volatile and stores up to 16,000 sets of readings. Measurements are linear, in any interval between 5 seconds and 99 hours.
See the Model 3001 Gold Data Sheet for more information on the Levelogger Series of dataloggers, accessories and software.
Barometric Compensation and Calibration Wizards guide you through the calibration process and compensation, to provide corrected data. Levelogger Software allows you to easily program your preferences, download data, and display data in a graph or table format or export to other programs. Temperature compensation is automatic, but temperature variations can also be displayed.
The Real-Time View option allows immediate viewing of live conductivity, water level and temperature readings. Leveloggers are easy to deploy; installation can be with direct read cables or wireline/rope suspension, avoiding the use of vented cables. (See Model 3001 Gold Data Sheet).
The LTC Levelogger Junior is SDI-12 compatible, can communicate with a Leveloader Gold data transfer device, and is able to integrate into a Solinst STS Gold Telemetry System.
An optional Biofoul Screen provides extra protection for the LTC Levelogger Junior pressure and conductivity sensors in harsh environments.
When an LTC Levelogger Junior is deployed for an extended period, there is the risk of biofouling on the pressure sensor and/or conductivity cell, which can compromise their readings.
The Biofoul Screen is designed to reduce the unwanted buildup of microorganisms, plants, algae, or organisms such as barnacles and mussels, on the instrument sensors. The Biofoul Screen consists of a Delrin sleeve wrapped with copper wire. It simply slips onto the sensor end of an LTC Levelogger Junior, where it is held in place by compression fit.
Using the natural anti-fouling characteristics of copper, the Biofoul Screen is an affordable option to lengthen the time an LTC Levelogger Junior can be deployed. It reduces site visits and time spent cleaning Leveloggers, and improves long-term performance by ensuring accurate sensor measurements.
