產(chǎn)品說(shuō)明:
JSR0302高真空減壓蒸餾測(cè)定儀 一、符合SH/T0165標(biāo)準(zhǔn) 二、主要技術(shù)參數(shù) 真 空 泵:抽氣速率2升/秒 顯示方式:數(shù)字顯示 壓力顯示:數(shù)顯薄膜真空計(jì)、壓力自動(dòng)平衡 殘 壓:2 ±0.25mmHg 工作電源:AC220V±10% 50HZ 三、性能及特點(diǎn): 1、采用高精度薄膜電子真空計(jì)測(cè)量真空度,數(shù)字顯示壓力,并用自動(dòng)和手動(dòng)方式控制殘壓波動(dòng)使其達(dá)到較高精度。 2、采用精密針型調(diào)節(jié)閥門調(diào)節(jié)殘壓,使殘壓精確穩(wěn)定,且波動(dòng)很小。 3、主機(jī)和真空泵采用分體式,消除了震動(dòng),真空壓力計(jì)與緩沖罐之間、主機(jī)與真空泵之間均采用符合國(guó)家標(biāo)準(zhǔn)的真空快速連接器,操作快捷方便并無(wú)泄漏。 4、采用熱風(fēng)恒溫系統(tǒng),數(shù)字顯示恒溫區(qū)溫度,在分餾瓶支管處不會(huì)產(chǎn)生冷凝阻塞現(xiàn)象。 JSR0302 high vacuum vacuum distillation tester I. Comply with SH/T0165 standard Ii. Main technical parameters True air pump: pumping rate 2 l/s Display mode: digital display Pressure display: digital film vacuum gauge, pressure automatic balance Residual pressure: 2 ±0.25mmHg Power supply: AC220V± 10% 50HZ Iii. Performance and Characteristics: 1. The vacuum degree is measured by high-precision thin film electronic vacuum gauge, the pressure is displayed digitally, and the residual pressure fluctuation is controlled automatically and manually to achieve high precision. 2, the use of precision needle adjustment valve to adjust the residual pressure, the residual pressure is accurate and stable, and the fluctuation is small. 3. The main machine and vacuum pump are divided into two parts to eliminate the vibration. Vacuum quick connectors in accordance with national standards are used between the vacuum pressure gauge and buffer tank and between the main machine and vacuum pump. 4. Adopt the hot air thermostatic system and digital display the temperature of the thermostatic area. There will be no condensation and obstruction at the branch pipe of the fractionator. |
