舒茨SPTr-GAS® ANALYZER 光声痕量气体分析仪，配置触摸显示控制屏，菜单结构分布合理，直观友好的操作界面，所有状态显示，门限值和报警值都以模拟及数字方式提供。实时显示检测浓度曲线，全自动或手动零点校准，由客户自由选择。检测精度高，稳定性好，适用于各类痕量气体浓度检测场合。
□ 有效屏蔽检测环境中湿度干扰：红外湿度检测模块直接配置在光声模块内部。
□ 屏蔽温度不稳的干扰：光声光谱加热到50度并维持此温度下进行检测。
□ 屏蔽其他气体干扰：通过检测微弱光声信号，通过精准信号放大并计算气体浓度
□ 内部集成气泵和三个采样点自动控制阀
□ 分析仪配置内部多种精细过滤器，过滤粉尘、水汽、干扰气体等
□ 每个检测点附近采样管上安装可更换滤尘器
□ 自动用空气校准零点，全自动执行，无需手动
光声光谱法是基于光声效应的新型光谱技术，有别于传统的红外光谱技术，它将光信号有效转换成声信号，并通过精密微音器对声音信号的检测计算得到最终的气体浓度。由于光声光谱技术的特殊光学结构以及在信号采集、信号处理过程中的特殊计算过程，使此方法能高效采集微弱光声信号，并有效剔除背景信号的干扰，非常适用于痕量气体浓度检测领域，以及在复杂环境中的无干扰检测。
