浙江省计量检定所一九八三年研制成的BNC—1型标准粘度槽是一种精密恒温水槽,工作区宽并透明可见,可用于检定一等二等标准粘度计和精密测量液体的粘度。它的温场主要指标是在其控温范围内(15—40℃),槽中两点间同时刻的温差(均匀性)不超过0.005℃;槽中一点温度的变动幅度在半小时内(稳定度)不超过0.005℃。这类精度的温
The BNC-1 standard viscosity tank developed by Zhejiang Metrology & Testing Institute in 1983 is a precision thermostatic water tank with a wide working area and transparent visible. It can be used to test the viscosity of first-class and second-class standard viscometers and precision measuring liquids . Its temperature field is the main indicator of its temperature range (15-40 ℃), the same point in the slot at the same time the temperature difference (uniformity) does not exceed 0.005 ℃; slot a little temperature change within half an hour Stability) does not exceed 0.005 ℃. Such precision temperature
