PLC221 determination of distillation range tester

A, application and applicable scope

The instrument is according to the regulations of the people's Republic of China standard GB/T6536 "petroleum products Determination of distillation method" the requirements of design and manufacture, is suitable for the determination of distillation according to the criteria of GB/T6536 for gasoline, aviation gasoline, jet fuel, special the boiling point of the solvent naphtha, distillate fuel, diesel, and similar petroleum products.

Two, main technical parameters and technical features

(a) the main technical parameters

The working power supply: AC220V + 10%, 50Hz.

The electric heating power: 1000W.

The cylinder volume: 100 ml, 1 ml of indexing.

The distillation flask: 125mL, meet the requirements of GB/T6536.

The thermometer: Immersion rod type, scale range respectively (-2 ~ +300) C and (-2 ~ +400) C two, dividing 1 C.

When a "furnace activity board: silicon carbide board manufacturing, aperture respectively Phi 38 mm, 50 mm in diameter.

Water temperature controller: temperature range: room temperature to 90 DEG C arbitrarily set.

The temperature control precision is + - 0.5 deg.

The temperature display: LED digital display.

Therefore the bath heating power: 1800W

Only the temperature of the environment: less than +30 DEG C.

That relative humidity is less than or equal to 85%.
