Introduction

 

Hotline thermal conductivity meter   Description:

First, sum up
the law of hot line that one kind measures the law (not a law of steady state) dynamically. Principle its to measure along sample length direction burying underground in sample centre line shape Wen Sheng for a fixed period of time of heat source. Measure the temperature of hot line and vary with time through the electric thermocouple that is welded on the mid point of hot line. Temperature of line this change to examine into material heat conduction function of coefficient. The instrument consults the standard: GB/5990-86 " fire-resistant products heat conduction coefficient test method (the law of hot line) that setting insulates against heat "; GB/T17106-1997 " refractory material heat conduction coefficient experiment method (parallel law) "; GB/T10297-1998 " determination (the law of hot line) of nonmetal solid material heat conduction coefficient ",etc.. This instrument mainly tests setting insulates against heat fire-resistant products, nonmetallic materials heat conduction coefficient at different temperature such as the material powdered. Apply to large and medium universities and colleges extensively, R&D institution, quality testing department and material for producing factory analyze that measures.
Second, main technical feature; 1, The coefficient of heat conduction tests the range: 0.015-1.7w/m• k; 2, Accuracy: ± 3%; 3, Can finish, cross line law, parallel law, realize test of controlled state to experiment temperature, test 1200 ℃ of temperature at most; 4, The sample size is required: 230*114*65(mm) ; 5, Can connect to the location machine, realize the computer tests, and realizes automatically the data are printed and exported;
