RVD-905A
portable moisture content meter
|
- 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-905A can measure moisture
content in construction materials (concrete, mortar, gypsum, etc...)
- Air temperature/humidity:
OPTIONAL - If the probe DSVT-05A is delivered,
RVD-905A 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-905A device
- Hammer action electrode
- Connection cable
- Probe for air temperature measurement
- DSVT-05A 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-905A 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-05A is delivered (optional).
Main characteristic of RVD-905A 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.

VP-01 device for sawdust moisture content
measurement is sold separatelly. It is specially modified
aluminium cylinder with RVD-905A mounting bracket. Sawdust in the
cylinder is compressed during measurement, and RVD-905A is used to
perform MC reading. Protection feature is implemented to protect
device from exceeded pressure and damage. |
 |
VP-02 device for sawdust moisture content
measurement is sold separatelly. It is consist sawdust bowl that connects to RVD-905A 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. |
 |
Concrete and other building materials moisture content probes
are used without contact mass. it is enough to drill 2 holes
in the concrete and place probes connected to RVD-905A in them.
After measurement parameters are adjusted, measurement can be
performed.
|
 |
Air temperature and relative humidity is performed
when probe DSVT-05A
is attached to RVD-905A. |
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).
