Solinst 107 Water Depth, Temperature and Conductivity Meters

$ 1,071.90 USD

Accuracy and Reliability with Solinst 107 Meters

Precise Measurement of Water Depth, Temperature, and Conductivity

Ideal for profiling conductivity and temperature in wells and open water, for saltwater intrusion studies, and as a general indicator of contamination levels. The 3/4" (19 mm) diameter probe is attached to the Solinst PVDF flat tape, laser-marked with precision every 1/100 ft or every millimeter. Lengths up to 1000 ft or 300 m, mounted on a Solinst reel.

The conductivity range is 0-80,000 µS/cm. Conductivity and temperature readings are displayed on a rotating LCD screen on the reel face. Conductivity accuracy is 5% of the reading or 100 µS (whichever is greater). A light and buzzer briefly activate when the probe's zero point enters the water. The water depth and depth of the displayed readings are read from the tape. The 9V alkaline battery is housed in an easily accessible battery drawer and provides up to 90 hours of use.

Highlighted Features:

• Ideal for profiling conductivity and temperature.
• Fast response, easy to use.
• Durable design.
• Reliable and built to last.
• Tape lengths up to 1000 ft (300 m).
• Robust Solinst reel and precision laser-marked PVDF tape.
