三. 技术参数
1. 光电流稳定度: ≤ ±1%T/3min 2. 透射比准确度: ≤ ±1.5%T 3. 透射比重复性: ≤ 0.5%T 4. 波长： 412 nm 5. 抑制率测量范围: 0～100% 6. 反应显色测试时间: 1～999 秒任选 7. 仪器外形尺寸：310mm×310mm×140mm 8. 重量：2.95kg（带电池 3.5kg）
在一定条件下，有机磷和氨基甲酸酯类农药对胆碱酯酶正常功能有抑制作用，其抑制率与农药 的浓度呈正相关。正常情况下，酶催化神经传导介质水解，其水解产物与显色剂反应，产生黄色物 质，用 NY-8D 农药残留快速测试仪测定吸光度随时间的变化值（△A）计算出抑制率（I），通过抑 制率可以判断出样品中是否有高剂量的有机磷或氨基甲酸酯类农药的存在。
操作反应速度快。 4. 光源采用发光二极管，具有节能、环保、省电、寿命长、响应速度快等优点。 5. 8 通道测试技术，一次可检测 8 个样品，同时显示测量结果。 6. 无机械运动部件，抗干扰，抗振动，性能稳定可靠。 7. 内部微处理器对电源、线路、光源等进行自诊断。 8. 可随时按检测日期和ቤተ መጻሕፍቲ ባይዱ测编号查阅、打印、删除存储测量数据。 9. 仪器配备 RS-232 接口和 USB 接口，可通过计算机进行数据处理和统计分析。 10. 监控网络信息功能强大，包括测量数据系统和监控管理系统，实施数集、统计、查询、交换和
I =(△A0-△At)/ △A0×100％ 其中：
I：酶的抑制率 △A0：对照溶液吸光度随时间的变化值 △At：样品溶液吸光度随时间的变化值
二. 仪器特点
1. 仪器全塑机壳，流线型外观设计（外观专利号：ZL200830111211.8），表面经过特殊处理，抗氧 化、耐酸碱。
2. 大屏幕液晶保护屏，采用钢化玻璃，抗划伤，屏幕清晰，界面人性化，读数直观。 3. 采用软按键，寿命长达 50 万次，具有防水、防尘、可清洗、消毒、抗菌、防静电、使用无噪音、
