產品說明：

JSN1101石油瀝青自動脆點測定器

一、符合GB/T4510標準

二、主要技術參數：

溫度范圍：常溫～-38℃ （20℃室溫）

恒溫精度：±0.5℃

冷浴尺寸：240×175×120 mm （長×寬×高）

外形尺寸：600×500×630 mm （長×寬×高）

整機重量：32Kg

三、儀器組成：

1、彎曲器：由兩只同心的玻璃管組成，其下端設有鋼夾鉗，在兩夾鉗之間的內管部分留一狹縫，以便于內管的溫度計的水銀球露出。轉動手柄可以使內管上下移動，并從而改變夾鉗間的距離。手枘每轉動10圈，夾鉗間的距離由起始的40±0.1mm變到36.5±0.1mm；

2、鋼片：長41±0.05mm，寬20±0.2mm，厚0.15±0.02mm有彈性的平鋼片不用時要使之處于展平狀態；

3、冷卻器：雙層杜瓦瓶，通過循環恒溫浴提供冷液；

4、溫度計：刻度范圍－38~+30℃、0.5分度；

I. It conforms to GB/T4510 standard

Ii. Main Technical parameters:

Temperature range: normal temperature ~ -38℃ (20℃ room temperature)

Constant temperature accuracy: ±0.5℃

Cold bath size: 240×175×120 mm (length × width × height)

Dimensions: 600×500×630 mm (length × width × height)

Machine weight: 32Kg

Power supply: AC220V±10% 50HZ

Iii. Instrument Composition:

1. Bending device: It is composed of two concentric glass tubes with steel clamps at the lower end. A slit is left in the inner tube between the clamps so that the mercury ball of the inner tube thermometer can be exposed. Turning the handle allows the inner tube to move up and down, thereby changing the distance between the clamps. Each 10 turn of the hａnd square will change the distance between the grips from 40±0.1mm to 36.5±0.1mm;

2. Steel sheet: Flat steel sheet with a length of 41±0.05mm, a width of 20±0.2mm, and a thickness of 0.15±0.02mm shall be flattened when not in use;

3. Cooler: double-layer dewar bottle, providing cold liquid through circulating constant temperature bath;

4. Thermometer: scale range: -38~+30℃, 0.5 degree;
