FSIQ3 FSP3现货频谱分析仪FSIQ3 FSIQ3 FSP3现货频谱分析仪FSIQ3

选用我公司二手仪器的优势是：

1、与新购仪器几个月的供货期相比，购买二手仪器的供货期要短的多。

2、在时间就是市场的今天，优势无疑是为明显的。

2、二手仪器的价格便宜，基本为新购仪器价格的20%～50%。在电子技术迅 速发展的今天，仪器的更新也在加快，投资越少则风险越小。

3、为了让您放心地使用我们提供的二手仪器，我们销售的二手仪器可以做到：保修半年到一年不等

      

      本公司现在新进了一批频谱分析仪、网络分析仪、信号分析仪、示波器、综合测试仪、音频分析仪、EMI接收机等射频类仪器，对新老客户在价格方面也在做优惠活动！欢迎选购！欢迎来电咨询!期待顾客上门看货!您的满意是我们zui终的追求!
