Water Level Meter
Automatic Water Level Logger
Model : HOBO U20
The HOBOware™ Pro software ( sold separately) provides easy conversion to accurate water level readings, fully compensated for barometric pressure, temperature and water density. An extra water level logger can be used for barometric compensation when needed ( one barometric data set can be used with all water level loggers in that area).
Other features include an Optical/ USB interface, a durable ceramic pressure sensor, and multiple-rate sampling for faster sampling at critical times such as when pumping starts or stops. Includes calibration certificate of accuracy versus NIST-traceable standards at three pressure points distributed through the range.

Optic USB Base Station : Required for communications between the HOBO Water Level Logger and a PC. Simply plug the Optic Base Station into a USB port on the PC and the Water Level Logger into the Optic Base Station. A full Logger offloads in less than 30 seconds
Water Level Logger
Model : SOLINST GOLD
The Levelogger can be easily programmed using the optical reader included in either the optional standard communications package or the optional direct read communications package. After the Levelogger is placed in the optical reader and attached to your computer, simply fill in the requested site information and choice of sampling regime.
Measurements can then be taken immediately, or a future start time can be chosen. Using the direct read communications package and a direct read cable assembly ( each sold separately) , data can conveniently be retrieved and viewed from the Levelogger at any time. To connect the direct read cable, remove the top cap of the Levelogger and attach the cable.

Water Level Loggers 100 Meter
Model : SOLINST 101
These top-of-the line water level meters provide features you’ ve been asking for: a 3/ 8" W polyethylene tape line with black graduations permanently embossed; seven stranded stainless steel conductors in the tape line; light and audible buzzer which sounds when contact is made with water; external sensitivitiy control for varying water conductivity; and a sturdy, stand-alone reel with on/ off switch, brake and carry handle ( carrying cases are sold separately below) .
Model 101
The Model 101 is available in either English or Metric in two versions, one with a 0.5" O.D. P2 stainless steel probe and the other with a 0.625" O.D. P6 environmental stainless steel probe. The P2 probe is designed for momentarily going underwater and is repairable. The P6 probe is completely submersible for extended periods of time and is rated for pressure up to 1, 000' underwater. The P6 probe is replaceable but not repairable.
Powered by 9 volt battery which is located in an easy access drawer in the reel. English tape line: black graduations in feet, 10ths and 100ths with markings every 1/ 100 ft. and foot marks in red. Metric tape line: black graduations in meters, centimeters and decimeters with markings every millimeter and meter graduations in red.
Digital Depth Sounders
Model :SPEEDTECH SM5
Available in two models, one features a built-in transducer and the other features an external transducer on a 12' cable. Waterproof to a depth of 150' ( 50m) both sounders measure depths in feet or meters in a range of 1.8' to 260' ( 0.6m to 79m). The transducer sends high frequency pulses to the bottom of a body of water where these pulses are reflected back and converted to electrical pulses that are amplified and displayed on the easy-to-read LCD.
Minimum Depth : 1.8' ( 0.6m)
Maximum Depth : 260' ( 79m)
Accuracy : ± 1%
Frequency : Built-in transducer model ( 90100) , 400 KHz
External transducer model ( 90101) , 200 KHz with a 24°

Digital Sonar Gun Depth Sounders
Model : HAWK EYE
Compact and effective. Built to be handheld... in fact you can aim the beam of this Sonar wherever you want to see, just like an underwater flashlight! Accurately provides instant depth readings, from 2 12 to 199 feet. At the press of a button the display gives real-time temperature ( water or air) and fish readings. Use it in the winter to shoot through ice BEFORE cutting your hole. Use it in the summer as a range finder and temperature meter while diving. Use it as a backup depth sounder on your pleasure boat or scan for channels in your dingy.
