此款糖度计有大批现货,因规格繁多,需要购买的亲们请先咨询店主型号哦!简介:当光线通过不同浓度的液体时会产生不同的折光角度,通过比较折光角度得出液体浓度值。折光仪据此原理设计而成。 DMD系列目测折光仪具有结构简单防震、操作携带方便、视野清晰、价格低廉等优点。糖系列应用在罐头食品、果汁制造、酿酒发酵、水果蜂蜜采收等领域。盐系列应用在海水养殖、水族馆、生理盐水制备等领域。医用系列应用在血清蛋白、尿液比重的检测。工业系列应用在汽车电瓶液、冷冻液、清洗液的检测,机床润滑液、切削液的检测。DMD系列目测折光仪能满足不同用户的检测要求。说明:仪器结构:1.棱镜座 2.检测棱镜 3.盖板 4.调节螺丝 5.镜筒和手柄 6.视度调节手轮 7.目镜折光仪是根据不同浓度的液体具有不同的折射率这一原理设计而成的。它具有快速、准确、重量轻、体积小等优点。使用方法:打开盖板(3),用软布仔细擦净检测棱镜(2)。取待测溶液数滴,置于检测棱镜上,轻轻合上盖板,避免气泡产生,使溶液遍布棱镜表面。将仪器进光板(3)对准光源或明亮处,眼睛通过目镜观察视场,转动目镜调节手轮(6),使视场的蓝白分界线清晰。分界线的刻度值即为溶液的浓度。校正和温度修正20℃环境下,仪器在测量前需要校正。取标准液一滴,涂抹在兰色检测棱镜上,然后把标准玻璃块亮面盖在上面,拧动零位调节螺钉(4),使分界线调至刻度78.8%位置。擦净检测棱镜后,可以进行检测。如果测量时温度高于或低于20℃,利用温度修正表,在环境温度下读得的数值加(或减)温度修正值,获得准确数值。附表:糖度读数之温度修正表。注意事项本仪器系精密光学仪器,在使用和保养中应注意以下事项:在使用中必须细心谨慎,严格按说明使用,不得任意松动仪器各连接部分,不得跌落、碰撞,严禁发生剧烈震动。使用完毕后,严禁直接放入水中清洗,应用干净软布擦拭,对于光学表面,不应碰伤,划伤。仪器应放于干燥、无腐蚀气体的地方保管。避免零备件丢失。糖度计读数之温度修正表 浓 度 (%)0510152025303540455055606570温度℃10从读数中减去0.50.540.580.610.640.660.680.70.720.730.740.750.760.780.79110.460.460.530.550.580.60.620.640.650.660.670.680.690.70.71120.420.450.480.50.520.540.560.570.580.590.60.610.610.630.63130.370.40.420.440.460.480.490.50.510.520.530.540.540.550.55140.330.350.370.390.40.410.420.430.440.450.450.460.460.470.48150.270.290.310.330.340.340.350.360.370.370.380.390.390.40.4160.220.240.250.260.270.280.280.290.30.30.30.310.310.320.32170.170.180.190.20.210.210.210.220.220.230.230.230.230.240.24180.120.130.130.140.140.140.140.150.150.150.150.160.160.160.16190.060.060.060.070.070.070.070.080.080.080.080.080.080.080.0820 00000000000000021加在读数上0.060.070.070.070.070.080.080.080.080.080.080.080.080.080.08220.130.130.140.140.150.150.150.150.150.160.160.160.160.160.16230.190.20.210.220.220.230.230.230.230.240.240.240.240.240.24240.260.270.280.290.30.30.310.310.310.310.310.320.320.320.32250.330.350.360.370.380.380.390.40.40.40.40.40.40.40.4260.40.420.430.440.450.460.470.480.480.480.480.480.480.480.48270.480.50.520.530.540.550.550.560.560.560.560.560.560.560.56280.560.570.60.610.620.630.630.640.640.640.640.640.640.640.64290.640.660.680.690.710.720.720.730.730.730.730.730.730.730.73300.720.740.770.780.790.80.80.810.810.810.810.810.810.810.81
