Moisture Meters can be used for wood, Concrete, grain and various other materials and is read in %.

Moisture meters are great to measure the moisture content in bulk solids, liquids and some gases. Some devices use infrared (IR), radio frequency (RF), or microwave techniques to evaporate water from a sample. Others determine moisture content by measuring a material’s conductance, resistance, or capacitance and calculating a corresponding moisture value. Variables measured include relative humidity, absolute humidity, specific humidity, and dew point. Relative humidity is a measure of the amount of water in the air compared with the amount of water the air can hold at a measured temperature. By contrast, absolute humidity is the mass of water vapor in a given volume of air. Specific humidity is the absolute humidity divided by the total mass of the given volume of air. Dew point is a measure of the temperature to which air needs to be cooled in order for saturation to occur. Moisture meters that measure pressure and temperature are commonly available. These specialized devices often include special circuitry or additional probes.

There are several form factors for moisture meters. Many require a secondary device or instrument for data acquisition or the transmission of humidity information. Integrated circuit (IC) chips mount on printed circuit boards (PCB). Benchtop or floor-standing moisture meters include a full casing or cabinet and an integral interface. Handheld units include an integral probe and are designed to be operated while held in one hand. Gauges mount on walls, well, racks, or DIN rails and include an integral display. Both analog and digital devices are available; however, simple light emitting diode (LED) power indicators are not considered to be a display. Video display terminal (VDT) styles include cathode ray tube (CRT) monitors and flat panel display (FPD). Mounted transmitters do not include a display, but provide an integral sensor or probe. Analog current outputs include variable levels such as 0 – 20 mA or 4 – 2 mA. Common analog voltage outputs are 0 – 10 V and ±5 V.

The Molten Metal Pyrometer, ‘NUNES’ is a disappearing filament Optical Pyrometer, suitable for measuring high temperature of incandescent objects, in annealing and hardening furnaces, in firing kilns, for measuring the temperature of molten and flowing metal or glass as well as incandescent blocks during forging, pressing or rolling. The temperature measurement makes use of comparison between the brightness of an electrically heated and calibrated incandescent filament (reference light bulb) in NUNES and that of the object to be measured.

The special advantage offered by the NUNES is the light weight of the instrument which houses all components of the complete measuring equipment. Thus, it can be transported by means of a carrying strap from place to place without any inconvenience. Due to its appropriate design, the simple measuring principle used is the convenience of its operation. High accuracy measurements can also be carried out even by less skilled operators. An additional advantage is the suitability for carrying out measurements on very small surfaces of down to 2 mm diameter and a measuring distance of 60 cm. Every NUNES has two measuring ranges.
