E+E传感器EE820系列介绍
EE820 CO2 传感器经过优化，可用于严苛、苛刻的应用，例如孵化器、孵化器、牲畜畜舍或温室。
出众的准确度
多点 CO2 和温度工厂调整程序可在整个温度工作范围内实现出色的 CO2 测量精度，因此 EE820 甚至可以安装在室外。
长期稳定性
EE820 采用 E+E 双波长 NDIR CO2 传感器，可补偿老化效应，对污染高度不敏感，并提供出色的长期稳定性。
高抗污染性
EE820 具有坚固、功能强大的 IP54 外壳和特殊过滤器，即使在恶劣的环境中也可以使用。
快速响应时间
EE820 的快速响应时间版本配有安装在过滤器后面的强制空气循环模块。
模拟和数字输出
CO2 测量数据范围高达 10000 ppm，可在模拟输出（电压/电流）或采用 Modbus RTU 或 BACnet MS/TP 协议的 RS485 接口上获得。
The EE820 CO2 sensor is optimized for use in harsh, demanding applications, such as hatchers, incubators, life stock barns or greenhouses.
Outstanding Accuracy
A multiple point CO2 and temperature factory adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range, so the EE820 can even be installed outdoors.
Long-term Stability
The EE820 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability.
High Resistance to Pollution
With its robust, functional IP54 enclosure with a special filter the EE820 can be employed even in harsh environment.
Fast Response Time
The fast response time version of EE820 is fitted with a forced air circulation module installed behind the filter.
Analogue and Digital Outputs
The CO2 measured data range up to 10000 ppm is available on the analogue output (voltage / current) or on the RS485 interface with Modbus RTU or BACnet MS/TP protocol.
