The NEW Model 107 TLC Meter is ideal for profiling conductivity and/or temperature in wells and open water and for salt-water intrusion investigations. The TLC uses an "intelligent" conductivity sensor with platinum electrodes. The sensor is attached to SOLINST flat-tape, accurately marked every 1/100 ft or every millimeter. Lengths up to 300 ft or 100m, mounted on SOLINST reels. The conductivity range is from 0-80,000 µS/cm. Conductivity and temperature measurements are displayed on a rotating LCD screen on the face of the reel. Conductivity accuracy is 2% of reading from 100 to 80,000 µS/cm. A light and buzzer are briefly activated when the zero point of the probe enters water. The depth to water and depth of displayed readings are read off the tape. The 9V alkaline battery is housed in an easy-access battery drawer and provides up to 90 hours of use.
