- Data availability is highly increased over traditional pyranometers
- Needs very low power
- SR25 is an excellent reference for diffuse radiation
-
SR25 takes solar radiation measurement to the next level. Using a sapphire outer dome, it has negligible zero offsets. SR25 is heated in order to suppress dew and frost deposition, maintaining its high measurement accuracy. When heating SR25, the data availability and accuracy are higher than when ventilating traditional pyranometers. In addition, SR25 needs very low power; it only consumes 1.5 W compared to the usual 10 W for ventilation. The low thermal offsets make SR25 very suitable for measuring diffuse radiation. -
HFP01 is the world’s most popular sensor for heat flux measurement in the soil as well as through walls and building envelopes. The total thermal resistance is kept small by using a ceramics-plastic composite body. The sensor is very robust and stable. It is suitable for long term use on one location as well as repeated installation when a measuring system is used at multiple locations. If measuring in soil, in case a more accurate measurement is needed the model HFP01SC should be considered.
- Low thermal resistance (essential for use on walls and windows)
- Large guard area (required by the ISO 9869 standard)
- Low electrical resistance (low pickup of electrical noise)
- High sensitivity (good signal to noise ratio in low-flux environments such as buildings)
- Robustness, including a strong cable
- IP protection class: IP67 (essential for outdoor application)

FTN02 Field thermal needle system performs accurate on-site (field) measurements of the thermal resistivity and thermal conductivity of soils. Measurements with FTN02 comply with ASTM D5334 and IEEE 442 standards. The system is specifically designed for surveys that require measurements from the surface down to a depth of 1.5 m. Due to the long and thin lance to which the sensor is mounted, the insertion of the thermal needle into the soil requires just a small-diameter access hole, typically made using a ground drill. Using a lance rather than digging trenches saves time. FTN02 is operated and powered from the hand-held control and readout unit CRU02.- Suitable for on-site (field) surveys
- Easy data processing
- Local calibration / conformity assessment

VU01 is a high-quality ventilation unit for use with pyranometers and pyrgeometers. Its purpose is to improve the dependability of the measurement. Measurement accuracy improves because offsets are reduced. Reliability benefits from prevention of dew and frost formation and quick evaporation and sublimation of water and snow. ISO/TR 9901 “Solar Energy - Field Pyranometers - Recommended practice for use” recommends use of ventilators where high accuracy and reliability are required. VU01 is designed in agreement with the recommendations of ISO/TR 9901 and BSRN.- VU01 provides an airflow over the instrument body and dome and has two heaters on board to heat the air.
- VU01 is designed, using high-quality materials, in agreement with the recommendations of ISO/TR 9901 and BSRN.
- The footprint of VU01 is small, which prevents accumulation of snow
- Dew and frost formation is prevented.

The MTN02 performs fast measurements of the thermal conductivity and resistivity of soils. Measurement with MTN02 complies with ASTM D5334 and IEEE 442 standards. The system is primarily designed for laboratory (indoor) measurements but can also be used for on-site (field) measurements. MTN02 is operated and powered from the handheld control and readout unit CRU02.- Suitable for laboratory and field measurements
- Suitable for hard soils and concretes
- Easy data processing
- Local calibration / conformity assessment

STP01 accurately measures the temperature profile of the soil at 5 depths close to its surface. It is used for scientific grade surface energy balance measurements. The sensor is buried and usually cannot be taken to the laboratory for calibration. The on-line self-test using the incorporated heating wire offers a solution to verify STP01’s measurement stability.- High accuracy, scientific measurement of soil energy balance, with a high level of data quality assurance
- Thin, 0.6 x 10⁻³ m thickness, construction which leaves the soil structure intact
- Simple copper-core signal wire; no special connectors needed
- Self-test saves servicing time
