一、引言恒温槽是一种用于检定、校准各类温度计以及检定标准电池、标准电阻的必要恒温设备。测量恒温槽的温场性能可采用多种技术手段,出于经济成本或设备环境条件要求等考虑,很多计量单位更愿意采用双通道高精度数字测温仪配接高精密铂电阻温度计作为标准器,测量恒温槽的温场。本文介绍了采用双通道高精度数字测温仪测量恒温槽温场的操作技术和数据处理方法。
I. INTRODUCTION The thermostat bath is a necessary thermostat for calibrating and calibrating various kinds of thermometers and calibrating standard batteries and standard resistors. Measuring the temperature field performance of the thermostatic chamber can be used a variety of technical means, for economic costs or equipment environmental conditions and other considerations, many units of measurement are more willing to use dual-channel high-precision digital thermometer with high precision platinum resistance thermometer as a standard , Measure the temperature field of the thermostat. This article describes the use of dual-channel high-precision digital thermometer temperature field thermostat operating techniques and data processing methods.
