Hydrometer of ELVIZ - 2S (humidity analyzer)
The hydrometer (the humidity analyzer) is intended to ELVIZ - 2S for exact, fast and simple measurement of humidity of solid monolithic, loose, fibrous, pastelike materials, water suspensions and nonaqueous liquids in vitro by a thermogravimetric method.
Scope of analyzers of humidity of the ELVIZ series:
- agriculture,
- food industry,
- pharmaceutical industry,
- production of perfumery,
- production of construction materials,
- control testing laboratories TSSMIS (Centers of Standardization of Metrology and Certification),
- TsGSEN (Centers of the State Sanitary and Epidemiological Surveillance),
- SGI (State Grain Inspections).
Principle of operation of the analyzer of humidity of "ELVIZ - 2S":
Thermogravimetric express method: the analyzer fixes the starting mass of a sample, analyzes change of weight in the course of drying, fixes the moment of establishment of constant weight, makes calculation and brings results of measurement to the alphanumeric indicator: percentage of moisture in a sample.
On the alphanumeric indicator of the analyzer of humidity "ELVIZ - 2S" all important parameters of the ex - recop (measurement) are displayed: humidity, weight, analysis time, heating temperature.
At the time of the end of measurement the analyzer gives a sound signal.

Lack of MVI interesting you in the above list means a possibility of work with these materials on analyzers of the ELVIZ series. Now are developed, but MVI for malt, compound feeds, forages on the basis of herbs, for grain, oil - bearing crops and products of their processing (cake, meal, oil), dried vegetables and fruit, spices, vegetable medicinal raw materials, raw materials for production of mayonnaise (egg powder, melange), mincemeat, fish and fish products, tobacco, cotton, fabrics, wood shaving, paint and varnish production, construction materials (cement, sand, chalk, clay, forming mixes), the soil, peat, etc. are not certified yet. If the technique certified by GOSSTANDART the Russian Federation is necessary for you, then we can carry out all preparatory work for carrying out certification. Quotations of bodies of GOSSTANDART of the Russian Federation make 7000 - 10000 rubles for one technique.
All analyzers of humidity of the ELVIZ series pass primary checking in the Center of Standardization of Metrology and Certification. (period of validity of the certificate on checking of 12 months).
Periodic checking of analyzers of humidity of the ELVIZ series has to is carried out annually in regional TsSMiS or other organizations accredited for these works, by the approved technique of checking of MP33 - 243 - 06.
