		GPS16-HVS Garmin GPS Receiver The GPS16-HVS sensor receives signals from Global Positioning System (GPS) satellites, and then uses the signals to calculate its position and velocity. That data, plus an extremely accurate real-time reading, can be transferred to the datalogger for display or storage over time. Features GPS receiver with integrated antenna Calculates position based on signals from orbiting GPS satellites Provides a one-pulse-per-second output for timing measurements Manufactured by Garmin Request Quote View Literature

		CS10-L CR Magnetics Current Transducer The CS10 uses CR Magnetic's CR8459 Current Transformer to measure the approximate current over a range of 0 to 200 Amps. The CS10 outputs a millivolt signal allowing the transducer to be directly connected to the CR510, CR10X, or CR23X dataloggers. The CS10-L is intended for lower-accuracy applications such as motor or generator load conditions, efficiency studies, intermittent fault detection, and rough submetering. Features Measures current from 0 to 200 Amps Recommended for applications that do not require high accuracy Request Quote View Literature

		CS512 Dissolved Oxygen Sensor The CS512 is a rugged, low-maintenance dissolved oxygen sensor that is manufactured by OxyGuard. This sensor consists of a self-polarizing galvanic cell that generates a millivolt signal proportional to the amount of oxygen present in the measured medium (typically water). Oxygen diffuses through its membrane onto a cathode that produces a chemical reaction. An electrical current is produced by this reaction that is converted from microamps to millivolts by a resistor. Features Uses a galvanic cell to measure dissolved oxygen Improved mechanical design completely seals sensor and eliminates O-rings Measures temperature with a resistor PT4-L Agitator available Manufactured by OxyGuard Request Quote View Literature

		CS110 Atmospheric Electric Field Sensor The CS110 Electric Field Sensor measures the vertical component of the atmospheric electric field at the earth's surface. These atmospheric electric field measurements are useful for assessing the local lightning hazard and for thunderstorm research. Features Electric field measurement made with reciprocating shutter instead of the traditional rotating vane field mill Power requirements are low; 9.6 to 16 Vdc; peak-current demand is 750 mA during motor operation Reliability: Ultra-reliable metallic ground connection of stator/rotor (no rotating contact) CR1000 datalogger within the system provides flexibility for additional meteorological measurements, control, and network integration Connectors are provided on the CS110 for attaching wind speed and direction, temperature and relative humidity, solar radiation, and rainfall sensors Request Quote View Literature

		CS215-L CSL Temperature and Relative Humidity Sensor The CS215 is temperature and relative humidity sensor manufactured by Campbell Scientific Ltd. This probe uses a Swiss-made digital humidity and temperature element that provides good measurement accuracy and stability. The elements are based on CMOSens® technology, which have been tested for more than two years in Alpine conditions where they were shown to work to their specifications in extreme weather. One major benefit of the CS215 is the ability to change the sensor element in the field. Each sensor element is individually calibrated so no further adjustment of the probe is required; simply changing the element returns the probe to factory calibration state for both temperature and humidity, allowing low-cost field recalibration without lengthy interruptions to data collection. Features Uses a combined digital humidity and temperature element Field changeable element allows on-site recalibration Digital SDI-12 output Simple datalogger programming Low power consumption Request Quote View Literature

		CS408-L PressureSystems 500-series SDI-12 Pressure Transducers The CS408 is a submersible pressure transducer manufactured by Pressure Systems to measure surface water, ground water, or hostile fluid levels. Each transducer is individually calibrated, and ships with a calibration sheet. The sheet specifies I/O conditions, as well as actual data reflecting the unit’s static accuracy and thermal characteristics. A vent tube, which runs the entire length of the cable, vents to the atmosphere so the measurements do not have to be corrected for barometric pressure. A desiccant tube is included to extract water vapor from air entering the vent tube. Features • Constructed of 316 stainless steel • Pressure ranges are 5, 15, 30, 50, and 100 psi • Accuracy is ±0.05% FSO • Outputs pressure via SDI-12 digital interface standard • Manufactured by Pressure Systems Request Quote View Literature

		CS620 Water Content Sensor for HydroSense® System The CS620 is the sensor used in a HydroSense System. The Hydrosense system combines a compact, handheld display and a sophisticated soil water sensing probe in a portable package to provide quick and reliable soil water content measurements. Each measurement takes less than one second and is obtained by inserting the probe rods into the soil and pressing a single button on the display unit. A choice of 12- or 20-cm long probe rods makes HydroSense a versatile tool for monitoring and managing soil water in a wide range of conditions. Features • Uses time-domain reflectometry measurement technique • Designed for making attended measurements • Extra rods are available for replacement or varied depth measurement Request Quote View Literature
