Art.Nr.: GMH3851Produktbeschreibung
resistive measuring device for material moisture and temperature, without accessories, with data logger and programmable user defined characteristics
for wood, building materials, straw, hay, paper, textiles, etc.
general information:
GMH 3831 and GMH 3851 offer decisive advantages in handling, user-friendliness, functional range and accuracy. The absolute moisture of 494 materials is displayed directly and can be automatically converted to water content. he cumbersome use of calculation tables becomes a thing of the past. Additionally you get a moisture evaluation of the measured material (wet / dry).
- 4 freely programmable characteristics
- serial interface or analog output 0 V to 1 V, freely scalable
- calibration protocol incl.
- 494 material characteristics
- 466 wood characteristics
- 28 building material characteristics
applications:
precision measurements of sawn wood, chipboards, veneers, saw dust, wood wool, flax, straw, hay, concrete, bricks, screed, plaster, lime mortar, cement mortar, paper, carton, textiles, wood chips, professional moisture measurement in firewood, etc.
specifications:

| measuring range | |
| moisture: | 0 % to 100 % u (material moisture) 0 % to 50 % w (water content) (depends on selected characteristic curve) |
| temperature: | -40°C to +200°C (-40°F to +392°F) |
| instrument accuracy | (at nominal temperature) |
| wood: | ±0.2 % material moisture (deviation from corresponding characteristic curve in the range 6 % to 30 %) |
| building material: | ±0.2 % material moisture (deviation from corresponding characteristic curve) |
| temperature: | (external) ±0.5 % of m.v. ±0.3°C |
| characteristic curves: | 494 material characteristic curves |
| moisture estimation: | 9 steps (wet ... dry) |
| resolution: | 0.1 % or 0.1°C (0.1°F) |
