热电偶高温计使用方法 热电偶高温计放置的地方须空气清洁,不能受震动或碰撞,周围温度变化不能太大。如用电位差计,则适宜的工作温度在 0℃至 35℃之间。测量电动势的仪表须放置水平。延引线须与热电偶,最好能焊接紧固,如接触稍松则电阻增大,以致增大测量误差,延引线须有良好的 Thermocouple pyrometer method of use thermocouple pyrometer place to be clean air, can not be shock or collision, the surrounding temperature can not be too large. Such as the use of potentiometer, then the appropriate operating temperature between 0 ℃ to 35 ℃. Meters for measuring electromotive force must be placed horizontally. Extension lead should be with the thermocouple, the best welding can be fastened, such as the contact is slightly loose then the resistance increases, resulting in increased measurement error, the extension lead should have a good
