The CS225 is a prime example of our commitment to provide the highest-quality monitoring products in the world. Our revamped design, rigorous validation process, and stringent quality standards are all focused on providing the fantastic quality you require to reliably generate data you can trust, even in the harshest of environments. Learn more about the CS225's quality testing and validation process.

The CS225 temperature string uses multi-point temperature profiles and SDI-12 digital technology for simple integration and reliability. The CS225 consists of an arrangement of temperature sensors mounted in rugged steel-reinforced cable, permitting it to be buried, submerged, or integrated directly into structures. Temperature points are over-molded to provide long-term protection in all mediums. Each CS225 is custom manufactured.

Temperature profiling with the CS225 is suited for a wide variety of applications and environments, including the following:

  • Borehole temperature profiling and borehole ground measurement
  • Measuring geothermal heat gradient
  • Lake stratification and thermal stratification measurement
  • Soil temperature profiles
  • Water temperature profiling
  • Frost heave monitoring
  • Active layer thickness permafrost monitoring and permafrost depth measurement
  • Talik ground temperature
  • Heat flow measurement

The CS231 offers the same precise temperature profiling as our CS230 SDI-12 Temperature Profiler, but with a slimmer design for easier use in borehole and road applications. The CS231 requires a smaller installation hole when compared to the CS230. For road applications, this means easier drilling, as well as less time and material to backfill.

The CS231 SDI-12 Temperature Profiler uses SDI-12 digital technology for simple integration. SDI-12 does away with analog measurement inaccuracies and susceptibility to electrical noise. The CS231 consists of a rigid probe assembly and up to four optional external temperature probes. The rigid probe assembly maintains the precise position of the temperature points within the profile, while protecting the temperature sensors in all mediums for the long term.

The CS231 is suited for a wide variety of applications and environments. The completely sealed probe assembly and external probes permit the CS231 to be used in roadbeds, soils, and water (snow and ice). 

Applications where the CS231 is used include spring load adjustment, frost and permafrost monitoring, soil, and water or snowpack temperature profiling.

The SDMS40 is a powerful and cost-effective 2D multipoint, laser-based snowfall sensor. In the past, multipoint laser-based snow depth sensors have typically been complex and costly, so the practical SDMS40 was developed to address those issues. Performance and reliability of the device have been proven with thorough testing of the sensor and its measurement method. (Read the white paper.) With the SDMS40, you can enjoy accurate data from a compact, automated, multipoint scanning laser snow depth sensor at a reasonable price.

The ability to quickly and reliably detect the onset of snowfall and snowmelt is a highly sought-after feature in a snow depth sensor, and the SDMS40 does not disappoint. It is one of a few laser sensor models available in the world that can reliably detect the onset of snowfall and snowmelt, and of all the models available, the SDMS40 is the most cost-effective.

Campbell Scientific prides itself on the high quality and accuracy of its products. We won't put our stamp of approval on anything that does not meet our expectations or the needs of our customers, and we want to ensure you can trust the quality and accuracy of the SDMS40 like you would trust any Campbell system. So we field tested the SDMS line of snow sensors over three Canadian winter seasons. It has proven itself to be practical, accurate, and of excellent quality.

The SkyVUE™8 LIDAR Ceilometer is ideal for measuring cloud base heights and vertical visibility at airports, helipads (onshore or offshore), and other meteorological applications. The SkyVUE™8 measures the atmosphere with high stability and repeatibility, providing you with information on cloud base heights, sky condition (up to five layers), vertical visibility, and raw backscatter profiles. Notably, the ceilometer meets or exceeds all the necessary ICAO, CAA, and WMO requirements and recommendations.

Because of its robust construction, the SkyVUE™8 only requires minimal maintenance and can be continuously used in either static or mobile applications in harsh environments. Its compact design and low weight of 18 kg make it easy to transport and deploy.

With an operational reporting range of 8 km, the SkyVUE™8 has one of the highest in its class. It is easy to use yet features advanced signal processing and unique optics to provide superior resolution and performance.

The SkyVUE™8 has many standard features, from a tilting base and two-axis inclinometer for automatic correction of cloud base heights to heaters, blowers, and a sun filter for operation under all conditions—making deployments possible around the world.

Unique standard features include an easy-to-operate stratocumulus calibration, long-life back-up battery, and twin clocks to augment its many continuous diagnostic self-checks and provide assurance of continuous, reliable, and accurate performance.

The HygroVUE™10 offers a combined temperature and relative humidity element in an advanced digital sensor that is ideal for weather networks. The electronics within the sensor provide accurate measurements, and the sensor is easy to use. The digital SDI-12 output allows a simple connection and measurement by many data logging systems. Another benefit is that this digital output avoids the extra errors associated with measuring analog sensors.

A stainless-steel mesh filter on the HygroVUE™10 minimizes the effects of dust and dirt on the sensor while allowing air exchange around the sensor element and reducing the chances that condensation remains inside the filter cap. A small PTFE membrane filter is bonded to the surface of the element, which prevents any finer dust or mold from directly influencing the measurement.

Because the sensor housing is designed to withstand permanent exposure to various weather conditions and to fit inside a range of radiation shields (including compact shields), the HygroVUE™10 is truly suitable for a wide range of monitoring applications.

The HygroVUE™10 utilizes a latest-generation, Swiss-made, combined relative humidity and temperature element based on CMOSens® technology that offers good measurements, accuracy, and stability. Each element of the HygroVUE™10 is individually calibrated with the calibration corrections stored on the chip. You can easily change the sensor element in the field, which reduces your downtime and calibration costs.
