Biomass moisture meters: calibrations
In addition to standard calibrations, customised calibrations can be created for some moisture meters. For specific solid biomasses or mixed biomasses, the calibration of the moisture meter with the biomass to be measured allows having an accurate and direct measure for this biomass. The measurement is thus optimized. This service takes place in two phases.
Calibration using the oven drying methodLike standard calibrations set up in Humitest moisture meters, the creation of a new calibration of biomass provided by the client is achieved through oven drying at 105°C. The client specifies the range of measure he wants and provides a sample for which the wet water content is the highest point on the curve to create.
After receiving the client's sample, the calibration is created as follows:
- oven drying according to specific protocol,
- collection of data (mass, voltage and corresponding water content),
- creation of a calibration curve from these data.
Integration of the calibration curve in the moisture meterThe new calibration curve is set up in the moisture meter and the new selection of biomass appears in the selection menu with the name chosen by the client. After checking proper functioning and issuing a calibration certificate (optional), the moisture meter is despatched to the client.
This biomass moisture meter allows to measure water content of solid biomasses: wood chips, barks, plant pellets, wood shavings, sawdust, miscanthus, corn cob...
This moisture meter designed for the players of the food industrie allows measuring wet mass water content of precious grains like coffee, cocoa, peas, rice, linseed, sesame or sorghum.
This grain moisture tester makes measurements of water content in maize (corn U.S.), rye, triticale, wheat, spelt, oats, rape, pumpkin seed, peas, soya bean,
beetle bean, horse bean, sunflower seed, husked rice (brown rice), coffee (unhulled, hulled, roast, kibbled), poppy seed and jatropha in seconds.
The temperature and moisture measurements can be logged and downloaded to a PC.
The Humitest for turf moisture meter measures the water content and the temperature of turf with its one meter long probe.
This moisture tester measure material water content in bale or pile with an insertion probe of 60 cm length: cellulose insulation, hops bales, alfafa bales, sand, compost or substrate...
