Temperature and conductivity appear on the reel-mounted LCD, while water level and probe depth are read from the laser-marked flat tape.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for groundwater investigations and field monitoring, the 107 helps operators compare readings at selected depths to identify changes in water temperature and specific conductance. Choose an imperial configuration from 100 to 1,000 ft or a metric configuration from 30 to 300 m using the options on this page.\u003c\/p\u003e\n\n\u003ch2\u003eThree Measurements with One Instrument\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eWater level: Measure depth to water from a consistent reference point using the graduated tape.\u003c\/li\u003e\n  \u003cli\u003eTemperature: Read water temperature on the LCD while the probe is submerged.\u003c\/li\u003e\n  \u003cli\u003eConductivity: View temperature-compensated electrical conductivity to compare conditions at different depths or monitoring locations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWhen the probe’s detection point enters conductive water, a light and tone activate briefly to indicate water contact. Read the tape at your reference point to determine depth to water. For profiling, lower the probe to selected depths and allow temperature and conductivity readings to stabilize before recording them.\u003c\/p\u003e\n\n\u003ch2\u003eConductivity Profiling and Specific Conductance\u003c\/h2\u003e\n\n\u003cp\u003eThe 107 displays conductivity standardized to 25°C, also called specific conductance and identified as EC on the display. This temperature compensation helps operators compare readings collected under different water temperature conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe full conductivity display range is 0 to 80,000 µS\/cm, with a calibrated range of 500 to 80,000 µS\/cm. Manufacturer-stated conductivity accuracy is ±5% of the reading or ±100 µS\/cm, whichever is greater. A displayed value below the calibrated range should not be assumed to carry the same accuracy specification.\u003c\/p\u003e\n\n\u003cp\u003eConductivity profiles can support saltwater intrusion investigations, road salt impact studies, tracer tests, and assessments of changing groundwater conditions. Conductivity alone does not identify a specific contaminant, establish its concentration, or determine whether water is safe to drink.\u003c\/p\u003e\n\n\u003ch2\u003eTemperature Measurement\u003c\/h2\u003e\n\n\u003cp\u003eThe meter displays temperature alongside conductivity, allowing operators to document both at each selected depth. Solinst specifies temperature accuracy of ±0.2°C over the -15°C to +50°C measurement range.\u003c\/p\u003e\n\n\u003cp\u003eAllow sufficient time for the probe to equilibrate when moving between water zones with different temperatures. Recording readings before they stabilize can affect the usefulness of the resulting profile.\u003c\/p\u003e\n\n\u003ch2\u003eSubmersible Probe and Laser-Marked Flat Tape\u003c\/h2\u003e\n\n\u003cp\u003eThe 19 mm (3\/4 in) diameter TLC probe is submersible to the full length of the meter’s tape. Check the available clearance along the entire access path, including restrictions around pumps, tubing, and fittings, before selecting this meter.\u003c\/p\u003e\n\n\u003cp\u003eThe PVDF flat tape has permanent laser markings every 1\/100 ft on imperial configurations or every millimeter on metric configurations. Graduation spacing describes the distance between markings; it is separate from overall measurement accuracy.\u003c\/p\u003e\n\n\u003cp\u003eThe probe’s submergence rating does not apply to the reel. Keep the reel above water during use.\u003c\/p\u003e\n\n\u003ch2\u003eField Operation and Conductivity Calibration\u003c\/h2\u003e\n\n\u003cp\u003eThe portable reel includes an LCD, carrying handle, probe holder, brake, tape guide, and accessible battery drawer. A standard 9V alkaline battery provides up to 90 hours of use, and the electronics switch off after eight minutes of inactivity.\u003c\/p\u003e\n\n\u003cp\u003eThe meter supports one- to four-point manual conductivity calibration using the manufacturer’s specified standards. Check the probe in fresh calibration solution appropriate to your expected field range and follow the operating instructions for calibration, cleaning, and maintenance.\u003c\/p\u003e\n\n\u003ch2\u003eApplications for the Solinst 107 TLC Meter\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eManual groundwater level measurements\u003c\/li\u003e\n  \u003cli\u003eTemperature and conductivity profiling in wells and open water\u003c\/li\u003e\n  \u003cli\u003eSaltwater intrusion and salinity investigations\u003c\/li\u003e\n  \u003cli\u003eMonitoring changes associated with road salt impacts\u003c\/li\u003e\n  \u003cli\u003eTracer studies\u003c\/li\u003e\n  \u003cli\u003eComparing water conditions at selected depths and monitoring locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe Solinst 107 is a manually operated instrument and does not automatically log readings.
