H-310 Pressure Sensor

The H-310 pressure sensor is for ground water level monitoring. The H-310 is calibrated to 0-15psi (34.6ft, 10.5m) or 0-30psi (69.2ft, 21m) ranges with an accuracy of 0.02% FSO.

DH-21 Logger/Pressure Sensor

The DH-21 is a submersible pressure sensor and data logger for water level measurements. The DH-21 is calibrated to 0-15psi (34.6ft, 10.5m) or 0-30psi (69.2ft, 21m) ranges with an accuracy of 0.03% FSO.

 
Non-Submersible Pressure Sensors

H-350XL Pressure Sensor/Logger

The WaterLOG® Model H-350XL™ is a microprocessor controlled pressure sensor/data logger designed for remote operation.  This instrument is designed to be used with the H-355 Self Contained Bubbler System H-355. This unit can be interfaced with a wide range of communication options and sensors. The H-350XL can also be used as a sensor to be used with other datalogger systems.

H-355 - Bubbler System

The H-355 "SMART-GAS" system is designed to replace the heavy, dangerous, high-pressure gas bottles, oil sight feeds, flow regulators, and leaky manifolds found in gas purge pressure measurement systems. The 355 is reliable, light weight and low power for remote locations.

H-3531 Non-Submersible Pressure

The H-3531 is a non submersible dry gas pressure sensor for use in either nitrogen tank applications or bubbler systems. The H-3531 is calibrated to 0-15psi (34.6ft, 10.5m) or 0-30psi (69.2ft, 21m) ranges with an accuracy of 0.02% FSO.

H-3521 Fluid Pressure Sensor

The H-3521 "Fluid" is a pressure sensor designed to measure fluid directly. The sensor can measure water, antifreeze or other fluid pressure with an accuracy of better than 0.05% FSO. The sensor also works with rain gauges, snow pillows, artesian wells, piezometers and water tanks. The H-3521 is calibrated to 0-15psi (34.6ft, 10.5m) ranges or 0-30psi (69.2ft, 21m) ranges.
 
Non-Contact Water Level Sensors

H-3611, H-3612 Radar Level Sensors

The H-3611 and H-3612 series radars is a family of SDI-12 water level sensors. Typical applications include non-contact measurement of river, lake and reservoir water level. The H-3611 has a measurement range of 115ft (35m) while the H-3612 measures up to 229ft (70m). Accuracy for the sensors is +-0.12in (3mm).

 
Shaft Encoders

H-3301, H-3311, H-3342 Encoders

The H-3301, H-3311 and H-3342 are digital shaft encoders, which measure water level by monitoring the position of a float and pulley. The 3301 and 3311 encoders provide a 200 count per revolution resolution. The 3311 includes a built in LCD display while the 3301 does not.

The H-3342 is an absolute digital shaft encoder, which measure water level by monitoring the position of a float and pulley. The 3342 provides resolution of 65,536 counts per/rev. The encoder includes a display for viewing the reading.
 
Meteorological Sensors

H-340, H-340SDI Rain gauge

The H-340 is a precision tipping bucket rain gauge with a patented bucket tipping mechanism. The housing is durable extruded aluminum with a one-piece cast base. The H-340's counterpart the H-340SDI is a digital rain gauge capable of interfacing with SDI devices. Both rain gauges provide a 0.01"/tip (0.254mm) resolution.

H-375 Wind Speed/Direction

The H-375 is a high performance rugged wind sensor. The device is manufactured from corrosion-resistant material which make this device ideal for a wide range of wind measurement applications. The sensor interfaces directly to all waterlog products.

H-376 Temperature/Relative Humidity

The H-376 is a high performance temperature/relative humidity sensor. The 376 combines a
high accuracy, capacitance type humidity sensor and 1000 ohm Platinum
RTD temperature sensor in one probe.

H-380 Temperature/Relative Humidity

The H-380 is a high performance temperature/relative humidity sensor. The innovative design make replacement and calibration unique within the industry and is 100% field interchangeable. Integration to waterlog equipment is simple and straight forward.

H-377 Air/Water Temperature

The H-377 provides an accurate cost effective means of measuring either air or water temperature. Accuracy at 25C: ± 0.1.

H-3791 Solar Radiation Sensor

The H-3791 pyranometer is used to measure global radiation in all types of applications and studies. The sensor features a silicon photovoltaic detector mounted within a fully cosine-corrected miniature head. In clear unobstructed daylight conditions, (for which purpose the sensor was calibrated) the sensor compares favorably with first class thermopile type pyranometers. In most natural daylight conditions the error is ± 3%.
Miscellaneous

H-335 - Inclinometer

The H-335 is a precision, single axis, wide range inclinometer which measures the angle (posistion) of radial water control gates. The H-335 is easy to use, works with any SDI-12 data recorder and can be interfaced with SCADA systems.
