Hydromette RTU 600

The RTU 600 is an electronic four-in-one meter designed for measurements of wood moisture, structural moisture, air humidity and temperature. The meter is equipped with a universal wood species corrector, suitable for every wood species and automatic temperature compensation from -10° - +90° C. Moreover, it can also be connected with the active measuring electrodes that are listed below:

  • B 50, B 60 and LB 71 for a non-destructive measurement of moisture and location of moisture in building materials
  • IR 40 EL for surface temperature measurement, thermal bridging and dew point
  • RF-T 28, RF-T 31, RH-T 37 EL and RH-T 37 EL flex for air humidity and air temperature measurement
  • as well as all Pt 100 probes of our range of temperature sensors

The Hydromette is especially applicable for painters, interior constructors, parquet layers, parquet flooring industry, wood working industries, artificial drying kilns, construction companies, architects, authorized experts, housing enterprises and administrative bodies for structural engineering.

Measuring Range

Structural materials:
0 - 80 digits (conversion into % of dry weight by graph)
0 - 199 digits (scanning range) with probes B 50, B 60 and LB 71
0.3 - 8.5 % of dry weight by conversion table using probes B 50, B 60 and LB 71
0.3 - 6.5 % CM with probes B 50, B 60 and LB 71 by conversion table
5 - 98 % R.H. using probe RH-T 37 EL (conversion into % of dry weight by sorption isotherms)

4 - 100 % m.c. by using the resistance measuring method

Air humidity:
5 - 98 % R.H. depending on RF-T probe

-200° - +600° C depending on Pt 100 probe
-20° - +199,9° C including infrared IR 40 EL probe


  • Handy quick moisture meter for fast single and series measurements
  • Direct displaying of moisture content via digital LCD, resolution: 0.1 % or 0.1 digit
  • The 81-step wood species correction enables very precise measurements for every individual wood species due to a variety-specfic calibration curve indicator
  • Automatic compensation of wood temperature in the range of  -10° - +90° C
  • Fast measurement of moisture in hardened building materials due to the resistance measurement method and a non-destructive indication/location of structural moisture due to the high frequency measuring principle
  • Precise measurement of temperature due to Pt 100 probes in 4-conductor technology
  • Fully automatic instrument setting

  • Power supply by 9 V dry cell
  • Dimensions: 180 [L] x 115 [W] x 53 mm [H], weight approx. 390 g
