CG 4 Pyrgeometer
The CG 4 Pyrgeometer is intended for high accuracy infrared radiation (IR) measurement research, from 4.5 to 42 µm. The CG 4 employs a unique solar blind ellipse shaped silicon dome, that offers a full 180° field of view, with good cosine response. The dome is hard carbon (diamond) coated, to protect from surface oxidation and scratching. The dome ring assembly is specially engineered to deliver optimal thermal coupling between the dome, dome mounting ring, and instrument body. The excellent dome to body thermal coupling eliminates the need for the conventional dome thermistor and dT (delta-T) dome/body temperature offset calculation (as is the case with other competitive manufacturer pyrgeometer models), even under direct solar load conditions. The CG 4 is therefore equipped with a single body thermistor, in addition to the instruments thermopile sensing element. To determine incoming sky or surface emitted IR, in W/m2 units, the output signal voltage of the CG 4 sensing element, body temperature, and the factory supplied CG 4 calibration coefficient, are all an integral components of the IR calculation.

Benefits

  • Easy set-up and operation (no dome thermistor) 
  • Excellent dome/body thermal coupling 
  • No batteries required 
  • Suitable for shaded or non shaded operation 
  • Compatible with Kipp & Zonen model CV 2 Ventilator

 CSD 1 Sunshine Duration Sensor
The CSD 1 is intended for the routine measurement of sunshine duration. Sunshine duration, as defined by the WMO, is the time interval in which the direct solar radiation component, the Sun, exceeds an irradiance level of 120 W/m2.

The unique design of the CSD 1 incorporates three photo-diodes of equal sensitivity, of which one photo-diode continuously measures the global sky irradiance (direct sun + diffuse sky irradiance) at all times. The remaining two photo-diodes measure a portion of the diffuse sky field only. The built-in electronics of the CSD 1 subtracts the acquired diffuse sky signal level from the global, to derive the direct solar irradiance signal level. The CSD 1 offers two output signal possibilities; a logic high/low output level (> 120 W/m2 = high logic), or a second milli-volt output signal level, that is proportional to the derived direct solar irradiance signal. The CSD 1 is intended to be used in conjunction with a data acquisition system, or (integrating) voltmeter.

Net Radiometer CNR 1

The Net Radiometer, CNR 1, is intended for the analysis of the radiation balance of Solar and Far Infrared radiation. The most common application is the measurement of Net (total) Radiation at the earth's surface.

Three of CNR 1 features are unique: first, it measures four radiation components separately, secondly, it is robust and virtually maintenance free, and thirdly, calibration of CNR 1 is relatively straightforward. These factors make the CNR 1 extremely suitable for long-term outdoor measurements. Especially in rough environments.

Generally speaking, the CNR 1 will measure with a higher degree of accuracy than other competitive instruments.

This is mainly because the dominant measurement of solar radiation with the CM 3 is accurate. Accuracy is also influenced positively by the possibility of viewing the four separate components of the radiation. In this way errors in the measurement can be detected more easily. Also contributing to a high degree of accuracy, is the CNR 1's high reliability, and, under conditions where other instruments would be covered by dew or frost, its incorporated heating.
 

  Solar radiation is measured by two pyranometers, one for measuring incoming radiation from the sky, and the other, which faces downward, for measuring the reflected Solar radiation. From these two pyranometers, albedo, the ratio of reflected and incoming radiation, can also be determined. The model type indication for the pyranometers is CM 3.


Schematic drawing of the CNR 1

Far Infrared radiation is measured by two pyrgeometers, one for measuring the Far Infrared radiation from the sky, the other from the soil surface. The model type indication of the pyrgeometer is CG 3. The CNR 1 can be used in two ways: measuring the four components separately, the four Separate Components Mode or measuring only Net Radiation, the Net Radiation Mode

NR Lite Applications:
Agricultural Meteorology: Evapotranspiration calculations and crop damage prevention.
Building Physics: Study of thermal stress and heat balance.
Road Safety: Highway condition monitoring.

CUV A1  B1 Narrowband Scientific UV Radiometers

CUV A1 and CUV B1 are delivered with a preliminary calibration; Kipp & Zonen feels that, at this moment, no generally accepted method of calibration is available. On request, Kipp & Zonen can build equipment with different spectral specifications based on the same design. 

CUV A1/CUV B1 Narrowband Scientific UV Radiometers

CUV A1 and CUV B1 are narrowband radiometers for measuring UVA and UVB irradiance. Designed in close cooperation with the Royal Dutch Meteorological Institute, the original purpose of the design was to offer a solution for continuous (non-scanning) meteorological monitoring of trends in UV radiation.

For analysing related atmospheric conditions it became apparent that it is impossible to rely on broadband UV measurements. To solve this problem, the CUV A1 and CUV B1 were designed with a sensitivity in a very narrow spectral band.

For CUV B1, the spectral wavelength was chosen at 306 nm. This wavelength represents an optimum of the multiplication of the human skin spectrum and the solar spectrum. The CUV A1 central wavelength of 386 nm was chosen because this particular wavelength is also used in the WMO air pollution network. In order to obtain the required accuracy, the UV meters are temperature stabilized to +40°C using a heating element. Two voltage outputs are available; the sensor signal (representing UV radiation) and the sensor temperature.

CV2 Data Sheet

Budget Price: £743

CV 2 Ventilation System
The CV 2 Ventilation System is designed to reduce system maintenance and enhance the operational performance of Kipp & Zonen CM 6B, CM 11, CM 21, and CM 22 pyranometer models, under all weather conditions. The CV 2 can also be used in conjunction with Kipp & Zonen CG 1 and CG 4 pyrgeometer models.

The internal blower fan of the CV 2 generates an airflow current that moves across the body of the mounted sensor, exiting through the ventilation cover exhaust port, and creating a laminar airflow across the sensors dome surface. The resulting effect is excellent dew, frost, and snow deposition prevention on the sensors dome surface, as well as reduced overall system maintenance.

The CV 2 has also been specifically engineered to promote optimal thermal equilibrium between the sensors dome and body surfaces; thus causing a notable reduction in infrared (IR) offset effect, and improving operational performance.

Benefits

  • Dew, frost, and snow deposition prevention 
  • Dome IR offset suppression 
  • DC voltage operation (remote sensing applications) 
  • Built-in resistive heating option (arctic/cold weather applications)

CM 7B Net Radiation Sensor CM 7B/CG R3 Net Radiation Sensor
The combination of an CM 7B albedometer and a CG R3 net pyrgeometer can be used as a net radiation sensor. The albedometer offers information on the net solar radiation (0.3 to 3 µm), and the net pyrgeometer on the net longwave radiation (4.5 to 42 µm). Addition of these two quantities will give net radiation. For data aquisition, four mV sensor outputs need to be sampled.

Net radiation, however, is only part of the information that is available. The upper CM 7B sensor measures global solar radiation, and the lower sensor measures reflected solar radiation. When (apart from the sensor mV signals) the CG R3 sensor temperatures are measured (2 x Pt-100 or thermistor), the upward and downward longwave radiation can be calculated. These values are representative of the soil surface temperature and the sky temperature respectively.

NEW UPDATED SPECIFICATION

Now comes with the latest CG R3 pyrgeometer.

The CGR 3 has been improved in many points over the CG 2, based on customer feedback and years of experience. The CGR 3 has a newly designed sunscreen that covers both body and connector to reduce the instrument temperature and further increase the accuracy.

In practical use, the combination of CM 7B and CG R3 offers the advantage of great robustness. Problems with dew and frost can be avoided by powering the heating resistors inside the CG R3 (12 or 24 VDC). Relative to conventional net radiation sensors with polyethylene domes, the CM 7B/CG 2 net radiation sensor requires little maintenance and is more stable and more reliable.  Budget Price: £2539
