Изобретение относитс  к области лабораторных измерений влажности образцов из различных материалов.The invention relates to the field of laboratory moisture measurements of samples from various materials.

Известен способ определени  остаточной влажности в материалах, но которому влажность определ ют но нотеро веса образца после высушивани  его в строго регламентированных услови х.There is a known method for determining the residual moisture in materials, but which is determined by moisture but not the weight of the sample after drying it under strictly regulated conditions.

Однако известным способом невозможно непосредственно контролировать сам процеес высушивани  образцов до требуе:-,юй величины остаточной влажности; врем , отводимое на операцию удалени  влаги из образца в цел х достаточной гарантии регламентируетс  с большим запасом; взвешивание высушенного образца из-за его гигроскопичности требует многих предосторожностей и стабильности условий при проведении этой операции дл  обеспечени  требуемой точности; дл  уверенности в результатах способ требует проведени  параллельных анализов; количество влаги, тер емое образцом при высушивании , определ етс  как разность двух больших величин, что вынуждает дл  обеспечени  точности брать большие навески иногда дорогих и дефицитных материалов, дл  этих целей используютс  весы повышенной точности.However, it is not possible in a known manner to directly control the process of drying the samples to the required: -, the value of residual moisture; the time allowed for the operation of removing moisture from the sample for a sufficient guarantee is regulated with a large margin; weighing the dried sample due to its hygroscopicity requires many precautions and stability conditions during this operation to ensure the required accuracy; for confidence in the results, the method requires parallel analyzes; The amount of moisture lost by the sample during drying is defined as the difference of two large quantities, which forces us to take large weights of sometimes expensive and scarce materials to ensure accuracy. For these purposes, weights of increased accuracy are used.

Дл  сокращени  времени измерени  и обеспечени  возможности наблюдени  процесса сушки в динамике по предлагаемому способу исследуемый образец и кулонометрический датчик помеш,ают в герметичный объем, высушивают его, в процессе сушки регистрируют ток через кулонометрический датчик, и о влажности образца в каждый момент времени суд т по величине электрического зар да, протекаюш.его через датчик к этому моменту времени.In order to reduce the measurement time and allow observation of the drying process using the proposed method, the sample under study and the coulometric sensor are placed in a sealed volume, dried, the current through the coulometric sensor is recorded during the drying process, and the sample humidity is measured at each time point the magnitude of the electric charge flowed through the sensor at this time.

Устройство состоит из влагомера с пультом питани  и измерений 2. К фланцу камеры влагомера вместо диафрагмы xpeiiHT приставку 3 с клапаном 4. Пружиной 5 клапан прижимаетс  к седлу и закрывает доступ влаги окружающей среды в камеру электролитических эле.ментов. Место соединени  влагомера 1 с приставкой 3 герметизируетс The device consists of a moisture meter with a power supply unit and measurements 2. Instead of a diaphragm xpeiiHT attachment 3 with a valve 4, to the flange of the moisture meter chamber instead of the xpeiiHT diaphragm valve is pressed against the saddle 5 and closes the access of environmental moisture to the electrolytic cell. The junction of the moisture meter 1 with the attachment 3 is sealed
