HF03 is a heat flux sensor that is applied in mobile measurements. It is combined with LI19, a high accuracy handheld read-out unit / datalogger. The combination HF03- LI19 is typically used to study heat flux levels of flares and fires, and to verify the performance of permanently installed flare radiation monitors and flare heat flux sensors. -
HF02 is a sensor that measures radiant heat flux or thermal radiation in the outdoor environment. A common application is monitoring the radiation emitted by flares. HF02 is certified for use in potentially explosive atmospheres, and is rated for radiation levels up to 15 x 10³ W/m². We recommend use of HF02 in a decision-supporting role only, and not to use measurements of HF02 as the main or sole source of information for judging safety.- Robust
- All-weather
- Suitable for potentially explosive environments

HF01 high temperature heat flux sensor measures heat flux and surface temperature at high temperatures, typically in industrial environments. It is particularly suitable for trend-monitoring and comparative testing. The same technology can be used to manufacture heat flux sensors for different applications.- Robust
- Suitable for use at high temperatures
- Low thermal resistance
- High sensitivity
- IP protection class: IP68

The GT series guiding tubes are accessories for Non-Steady-State Needle probes. They are intended to facititate measurements in hard soils, concrete, cement and bentonite. Also in case of measurements on large quantities of samples one can use several guiding tubes and one single needle. -
GG01 is a water-cooled sensor that measures heat flux. The Gardon gauge sensor is based on copper and copper alloys, and works at heat flux levels at which other sensors get toasted. Optionally GG01 can be equipped with a sapphire window; to measure radiative heat flux only, and not convective heat flux. GG01 has an on-board thermocouple type K and is available with various dedicated measurement ranges.- Withstands very high heat fluxes
- Fast response time
- Equipped with type K thermocouple to measure body temperature
- Suitable for use in high vacuum
- Safe storage with a practical protection cap

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

FHF05 is the product range to start looking if you consider measuring heat flux. Models are available in five different dimensions and sensitivities. All FHF05’s are flexible, have an integrated temperature sensor and have thermal spreaders to reduce thermal conductivity dependence. Rated temperature range is from –70 to +120 °C. FHF05 measures heat flux from conduction, radiation and convection. Optionally, black BLK and gold GLD stickers are available for all five models to separately determine heat transport by radiation and convection. In case the FHF05 series does not match your needs, have a look at other heat flux sensor models for special applications.- flexible (bending radius ≥ 7.5 x 10-3 m)
