<p>第一，性能指标方面：</p>

<p style="text-indent:33.0pt;mso-char-indent-count:2.75">如温度范围、光斑尺寸、 工作波长、测量精度、响应时间等<span lang="EN-US">;</span>环境和工作条件方面<span lang="EN-US">,</span>如环境温度、窗口、显示和输出、保护附件等<span lang="EN-US">;</span>其他选择方面<span lang="EN-US">,</span>如使用方便、维修和校准性能以及价格 等<span lang="EN-US">,</span>也对测温仪的选择产生一定的影响。随着技术和不断发展<span lang="EN-US">,<a href="http://www.hcjyet.com"><span lang="EN-US"><span lang="EN-US">红外测温仪</span></span></a></span>最佳设计和新进展为用户提供了各种功能和多用途的仪器<span lang="EN-US">,</span>扩大了选择余地。</p>

<p>第二，确定测温范围<span lang="EN-US">:</span></p>

<p>　 　测温范围是<span lang="EN-US"><a href="http://www.hcjyet.com"><span lang="EN-US"><span lang="EN-US">测温仪</span></span></a></span>最重要的一个性能指标。如<span lang="EN-US">HCJYET</span>（宏诚）产品覆盖范围为<span lang="EN-US">-50℃-+2200℃,</span>但这不能由一种型号的红外测温仪来完成。每种型 号的测温仪都有自己特定的测温范围。因此<span lang="EN-US">,</span>用户的被测温度范围一定要考虑准确、周全<span lang="EN-US">,</span>既不要过窄<span lang="EN-US">,</span>也不要过宽。根据黑体辐射定律<span lang="EN-US">,</span>在光谱的短波段由温度引 起的辐射能量的变化将超过由发射率误差所引起的辐射能量的变化<span lang="EN-US">,</span>因此<span lang="EN-US">,</span>测温时应尽量选用短波较好。</p>

<p>第三，确定光学分辨率<span lang="EN-US">(</span>距离及灵敏<span lang="EN-US">)</span></p>

<p>　　光学分辨率由<span lang="EN-US">D</span>与<span lang="EN-US">S</span>之比确定<span lang="EN-US">,</span>是测温仪到目标之间的距离<span lang="EN-US">D</span>与测量光斑直径<span lang="EN-US">S</span>之比。如果测温仪由于环境条件限制必须安装在远离目标之处<span lang="EN-US">,</span>而又要测量小的目标<span lang="EN-US">,</span>就应选择高光学分辨率的测温仪。光学分辨率越高<span lang="EN-US">,</span>即增大<span lang="EN-US">D:S</span>比值<span lang="EN-US">,</span>测温仪的成本也越高。</p>
