Water Level Instruments
Flat Tape Water Level Meter
Water Level Meters are used to measure the depth to water in wells, stand-pipes, and piezometers.
Round Cable Water Level Meter
This sturdy water level meter uses a small-diameter coaxial cable that is reinforced with a stainless steel internal cable and hot-stamp marked every 1/100-foot.The cable is reel mounted on a lightweight steel frame with a reel brake and has audible and visual alarms and sensitivity adjustment.
Interface Meter
Interface meters are used to measure the depth to the top of a floating petroleum layer and the depth to the top of the water surface beneath the floating layer.
Pressure Transducer
The INW PS9800 is a submersible analog pressure transmitter/ transducer for electronically measuring changes in water level or pressure in wells, tanks, surface water, and pipes. Our transducers readily integrate with virtually any data collection system.
Water Levelogger™
The Levelogger is a miniature pressure transducer and data logger in one submersible probe used for measuring water level and temperature changes over time in wells and standpipes.
Level and Temperature Logger
The PT2X is an extremely easy to use submersible Pressure Transducer and digital Data-Logger combined in one miniature stainless steel probe. Use the PT2X for slug testing, aquifer monitoring, stream or wetlands management, pump and remediation control, and industrial and process applications.
Wireless Remote Data Communication
Use the WaveData™ wireless data communication system and our logging sensors to obtain field instrument data remotely or to consolidate data from individual sensors across an entire site without trudging from installation to installation.
Multi-Function Dataloggers
Monitor and record virtually any type and any combination of sensors from pressure transducers to weather stations to water quality probes in applications as diverse as rainfall and water level monitoring, stream flow monitoring, remediation system monitoring and control, and industrial applications.
WATER QUALITY INSTRUMENTS
Single Parameter Testers
pH Tester
This is the world’s most convenient pH tester! This waterproof meter features a replaceable pH electrode, automatic temperature compensation, battery level indicator, automatic shut-off, and a display that shows pH and temperature at the same time.
ORP Tester
Our ORP tester performs quick and affordable tests. It has a replaceable ORP electrode and will operate for approximately 700 hours on one set of batteries.
Conductivity (EC) Tester
The pocket Conductivity tester has automatic temperature compensation, adjustable calibration, and replaceable circuit board. Approximately 150 hours of operation on a set of batteries. Choose uS/cm or mS/cm.

Turbidity Meter
This hand-held turbidity meter is ISO 7027 compliant, provides dual range readings, and can be automatically calibrated at two points. Includes 2 calibration solutions, measurement cup, and cap. A large digital readout displays the results in FTU’s.
Dissolved Oxygen Meters
YSI 550A
The YSI 550A DO meter is waterproof, rugged, and reliable. It allows simultaneous measurement of dissolved oxygen and temperature and features a backlit display, automatic push-button calibration, and a weighted, quick-sinking probe. The 550A also has a built-in calibration chamber, low-battery indicator, direct salinity, and altitude compensation. It will calibrate in % or mg/L saturation and displays temperature in user selected degrees C or F. The DO electrode is easily field replaceable, and the replacement membranes are built into screw-on caps. Battery life is rated at 2,000 hours.
YSI 55
The YSI 55 measures dissolved oxygen in water and displays the results in mg/L or % oxygen. Features a built-in calibration chamber and push-button calibrations. Provides direct salinity, altitude and automatic temperature compensation. Select cable length or select the detachable cable option.
Hanna 9142
The Hanna model 9142 is a moderately priced dissolved oxygen meter that is excellent for field use and suitable for down-hole or above ground measurements. The hand-held meter is waterproof, has a large digital display, two-button operation, and automatic temperature compensation. Two-point manual calibration can be easily performed in air at 100% saturation and with zero oxygen solution. Replacement membranes are pre-mounted in screw-on caps for quick field installation. The 9143 offers all the features of the 9142 plus an extended oxygen measurement range, salinity and altitude compensation, and automatic in-air calibration. Includes: meter, probe, 2 spare membranes, & electrolyte.
Portable Multi-Parameter Meters
Horiba U-22
The Horiba U-22 is an easy-to-use field instrument for simultaneous measurements of up to 13 parameters. The probe fits into 2-inch wells or can be used with the custom flow-cell. Readings are displayed on a handheld meter with digital readout, or the meter can be left in place to automatically log up to 1 month of data. Logged data can be transferred to the user’s PC. One-point calibration is simple using the multi-parameter “Auto-Cal” solution. Press one button for a simultaneous one-point calibration of pH, Conductivity, Turbidity, and DO. The system enables two-point calibrations where high-precision measurement is required. Individual sensors are housed in a rugged stainless steel probe with a permanently attached cable. Includes: pH, Conductivity, Dissolved Oxygen, Salinity, TDS, Turbidity, ORP, Temperature, and Depth.
In-Place Sensors
AquiStar Smart Sensors
AquiStar® Smart Sensors provide portable real-time measurement and long term data logging of individual water quality parameters for in-situ applications. The sensor and logger are built into a single stainless steel probe, which fits into 1.25-inch and larger monitoring wells, can be used in hostile water treatment environments, and can be fitted to pipes and tanks for process applications. Each sensor uses the latest technology to allow long installation time with minimum calibration or maintenance requirements. All sensors measure temperature.
