Why using 3 Tewameter® heads at the same time?
The Tewameter® Triple TM 330T offers all advantages of the "open chamber measurement" and has additional benefits:
The open chamber measurement of the Tewameter® is the only method to assess the TEWL continuously, which is necessary for most applications without influencing the skin surface. Numerous studies are available.
Probe only:
Dimensions: three measuring chambers: each 2 cm, Ø 1 cm, length of the probe: approx. 24 cm, width, when all chambers are located close together: approx. 6.4 cm, cable length: 1.3 m, weight: approx. 120 g
Resolution: relative humidity ± 0.01 % RH, Temp.: ± 0.01 °C, TEWL: 0.1 g/h/m², Measuring area: TEWL 0-320 g/h/m²
Operating conditions: T: 10-40° C, RH: 30-70 % RH
Measurement Uncertainty: for 10° C to 40° C and TEWL-values lower than 70 g/h/m²:
TEWL: ± 10 % of the measured value plus ±1 g/h/m² for RH between 5 % and 90 %, ± 15 % of the measured value plus ± 2 g/h/m² outside this range
Temperature (T): ± 0.2 °C for 10 °C to 60 °C and ± 0.5 °C outside this range
Relative humidity (RH): ± 2.0 % for 5 to 90 % RH and 10 °C to 60 °C, ± 3.0 % outside these ranges
