The drying scale is a precision device for the determination of moisture content in small samples of materials by drying the sample with halogen heaters. The drying scale is in use as a drying measurement tool as well as for determination of dryness content. Also it can work as a standard mg-scale. The drying scale uses heaters (2 x 200 Watts) to dry the sample in conjunction with a precision scale to measure the minute changes in weight as the sample dries. In general these units can be used in research, development and quality control. The materials to be tested are: food, sugar, salt, granulates, plastics, pellets, fibers, ..., but also liquids as sludge and mixtures of all kinds. So the drying scale is a multi purpose tool.
The software built into the system provides many different drying programmes and calculates various parameters for humidity and dry mass. A typical drying procedure involves choosing a drying temperature, a time interval - for example 100 degrees for 10 minutes and a mode - % solids. Automatic external calibration using either 100 g or 200 g calibration weight (depending on the model) guarantees ongoing accurate results. The integrated RS - 232 - interface enables you (with optional software-kit) to automatically send the drying data into a sequence table. This link shows an overview of the scales and scales we have available to meet your requirements.

Classic cases of use

In the quality control of goods, the moisture content is calculated to determine that the material does not possess excess of water, so the customer does not have to pay for it.  After the storage and the subsequent handling of granulates, moisture can be accurately determined to ensure a good property development in the production and processing of granulates.

Options
-ISO Calibration (ISO-PCE-MB)
The calibration procedure includes laboratory calibration process and ISO certification. The customers name and address is filled in. These certificates are comparable to NIST and UKAS certificates. They are accepted all over the world.

Software-Kit (PCE-SOFT-MB)
The kit includes a software for transferring weighing data to a PC or Portable and a rs-232-cable. The transferred data can also be sent to other calculation software as Excel ... The standard software is in English language
(others are available (French, German ...).

-RS-232-USB-Adaptor (RS232-USB)
In case your PC or Portable uses USB-Inter-faces, you can use the adaptor in connection with the standard rs-232-cable. A small software (covering all the actual drivers) is included.

-Printer (PCE-TDP)
The printer is used for direct output of weighing data. It will be delivered including rs-232-cable and net adaptor.

ISO calibration and certification
An ISO calibration certificate can be acquired for this drying scale. It includes a control document containing the company contact details consisting on a laboratory calibration and a certification to meet ISO standards. This means that the drying scale meets the minimum requirements of the national body of measurement and it can be included in your internal set of measuring instruments. Further information:

Calibration: Control of measurement magnitudes correction for the drying scale without the intervention in the measurement system, or the determination of the systematic display deviation in relation to the real value of the measuring magnitude.

Calibration document or certificate: document with the technical properties of the device according to the national organization of measurement.

Calibration interval: to perform correct measurements, devices must be calibrated at regular intervals. This period of time is called calibration interval.  It's difficult to determine this period with accuracy but you should consider the following factors:

·         Performance of the measuring instruments

·         Frequency of use

·         Operating conditions

·         Previous calibrations stability

·         Measuring accuracy required

·         Determining factors of the quality control systems used by companies

This means that user is in charge to check and control the interval between calibrations. We recommend that this internal between calibrations should be between 1 and 3 years. We can also offer our expert advice to solve any questionss relating to the process of establishing a calibration interval.

Take into consideration:
When a drying scale is calibrated, this should be done while the temperature sensor being used with the device is attached or with the sensor that came with the thermometer attached. The accuracy of the calibration depends on the device and the sensor combined. In the case of the PCE-T395 thermometer this means that the calibration should be done for up to four temperature sensors.
