  • Measurement:
    • Moisture content:
      measurement of all wood types moisture content in range 6% to 100% at the temperature in range -10°C up to 80°C (temperature compensation)
    • Moisture content in construction materials:
      OPTIONAL - When a special probe is delivered, RVD-905 can measure moisture content in construction materials (concrete, mortar, gypsum, etc...)
    • Air temperature/humidity:
      OPTIONAL - If the probe DSVT-03 is delivered, RVD-905 can measure temperature in range 5°C up to 85°C and relative air humidity in range 5 %RH up to 100 %RH
       
  • Device is delivered in a rigid plastic case with following content:
    • RVD-905 device
    • Hammer action electrode
    • Connection cable
    • Probe for air temperature measurement
    • DSVT-03 probe for air temperature/humidity measurement (OPTION)
    • Pair of probes for moisture content measurement in construction materials (OPTION)

Universal portable (hand held) moisture content meter RVD-905 is made for on-field wood, timber or pallets MC measurement of all wood types. It can be used as universal device for MC measurement because it can also measure:
- moisture content of saw dust when connected to VP-01 device (optional)
- moisture content of construction materials (concrete, gypsum, mortar, etc...) with special probes for concrete (optional) as well as
- air temperature and relative humidity inside the chamber when a probe DSVT-03 is delivered (optional).
Main characteristic of RVD-905 is its portability, since it is battery operated and is intended for usage in the drying chambers and on the field. Device is equipped with built-in indication that alert the user when the battery is low.

Device is very easy to operate with.
It has large LC display which shows all relevant data and flat keyboard for easy access to all functions and settings. For moisture content measurement of any wood type it is necessary to enter appropriate type of wood (one of 4 basic types according to data given in User's manual) with temperature compensation in range -10°C to 80°C. This compensation represent the temperature of wooden sample at the moment of MC measurement. Temperature compensation is not used for MC measurement of construction materials.


Uredjaj za merenje vlage pijevine VP-01 VP-01 device for sawdust moisture content measurement is sold separatelly. It is specially modified aluminium cylinder with RVD-905 mounting bracket. Sawdust in the cylinder is compressed during measurement, and RVD-905 is used to perform MC reading. Protection feature is implemented to protect device from exceeded pressure and damage.

Uredjaj za merenje vlage piljevine VP-02 VP-02 device for sawdust moisture content measurement is sold separatelly. It is consist sawdust bowl that connects to RVD-905 with special cable. The sawdust is pressurized in bowl to allow moisture measurement. Device has protection in order to prevent excessive pressure and damage to the device. The same system also provides uniform pressure that guarantees uniform measurement.

Sonda za vlagu i temperaturu DSVT-03 Air temperature and relative humidity is performed when probe DSVT-03 is attached to RVD-905.

NOTE: Since there are several configuration and delivery options, customer must specify which configuration wants upon ordering (with or without the special probes for air temperature / humidity measurement and probes for construction materials).
