This Hygro-Thermometer meets the GLOBE Protocols for air temperature, relative humidity, soil temperature and maximum-minimum and current temperatures. Features include large, bold numbers, a dual display for temperature and humidity, max/min temperature and humidity memory, and a freeze alert. Mounts easily by key hole, Velcro®, magnet or the flip-out desk stand.
Fish Ray Handheld Sonar Depth Sounder Model FR300
Operating Depth: 2’ to 399’.
Simply place the nose end of the Fish Ray in the water and pull the trigger to quickly obtain water depth measurements. Readings instantly appear on the digital LCD display in feet. Once you determine a stable bottom depth, you can then slowly sweep the Fish Ray through the water to scan for sudden depth changes that indicate the presence of fish or contour variations. The rugged, high-impact housing is waterproof and floats.
Global Water Flow Probe Hand-held Flowmeter, 3’ to 6’ Expandable
Ideal for storm run-off studies or flow measurings of rivers, streams, canals, and sewers. Incorporates true velocity averaging for the most accurate measurement possible. The probe shaft is available in lengths that extend from 3’ to 6’ and from 5’ to 15’. Located on the bottom tip is a protected Turbo-Prop sensor which uses the most advanced positive displacement technique available. For minimal friction, this 2” Turbo-Prop sensor rotates freely on a bearing shaft with no mechanical interconnections. Magnetic material in the propeller passes a pickup coil in the housing producing electrical impulses. These electrical impulses are then carried by wire to a readout display on top of the handle. This readout display amplifies and converts the signal into feet/meters per second readings. Instantaneous velocity and true average velocity are then displayed. A unique two-button keypad allows other functions to be displayed including minimum/maximum velocity, time-of-day, timer, totalizer for batch flows, and RPM for accurate low velocity measurement. Features a 30-record memory, padded gun-type carrying case, five-year long life battery for readout display (no battery required for Turbo-Prop), and low battery indicator. Probe can be extended up to 25’ with standard PVC pipe and electrical extension cable.

Hanna Instruments Model HI 98194 Multiparameter Waterproof Meter
The HI 98194 meter measures pH, ORP, EC, TDS, resistivity, salinity, seawater sigma, dissolved oxygen, atmospheric pressure, and temperature. This waterproof meter delivers reliable measurements and features a rugged IP67 waterproof enclosure. The meter includes a digital probe that is equipped with a built-in temperature sensor. Ports on the probe accommodate color-coded, field-replaceable sensors. In addition to auto-sensor recognition, the meter features automatic temperature compensation, automatic logging for up to 45,000 samples, and log-on-demand to store data at the press of a button. Logged data can be transferred to a PC using the included micro USB cable and software. GLP data from the previous five calibrations helps to ensure that Good Laboratory Practices are met. A dedicated Help key provides context-specific assistance on the backlit display. Includes probe with 4m cable, pH/ORP sensor, EC sensor, DO sensor, probe maintenance kit, calibration beaker, quick calibration solution, PC software, micro USB cable, batteries.
HawkEye® DepthTrax™ 1H Handheld Digital Depth SounderHawkEye® DepthTrax™ 1H Handheld Digital Depth Sounder
HawkEye DepthTrax 1H Handheld Digital Depth Sounder
The ultralight DepthTrax 1H delivers precise real-time depth readings from 2’ to 240’ with the slide of a magnetic switch. Slide the switch again to obtain current water or air temperature. Algorithmic programming reduces false readings, and Shoot-Thru Technology™ even allows readings through ice or boat hulls. In addition to a backlit LCD, the depth sounder features automatic gain and sensitivity adjustment as well as an impact-resistant housing that floats. The depth sounder is also submersible to 150’ for use as a rangefinder during snorkeling and diving. Wrist strap included.
Hondex Digital Depth Sounder
Waterproof to a depth of 150’ (50m), this sounder features a built-in transducer and measures 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. The seven-digit LCD is backlit for night use. This compact depth sounder transports easily and stores conveniently – it will even slip into a shirt pocket! Powered by a 9V DC dry cell battery (included), the sounder has a battery life of approximately 500 uses and automatically shuts off after 10 seconds. Wrist lanyard included.
Eno Scientific Well Sounder 2010 PRO
A highly accurate instrument designed for measuring static water level in wells, piezometers, or boreholes. This portable handheld unit uses sound waves to measure the distance from the top of the well to the water level, eliminating the need to lower anything into the well. Unlike standard water level tapes, these acoustic meters are free from well contamination issues, and there is no clean up and nothing to get stuck in the well. Simply place the probe into a well cap opening and turn the unit on. Within seconds, the unit will display the static water level measurement. Will work on crooked, straight, or coiled pipes with up to a 90% blockage. Requires no external equipment for configuration settings and is capable of logging, storing, and downloading 25 million time/date stamped data points. Key features include immediate data capture, auto temperature compensation, calculation of drawdown and recovery rates, real-time clock/calendar to time stamp the log data, USB download, plus it is weather-resistant.
