4 in 1 Probe Measures CO2. Humidity, Temperature and Pressure四合一测量仪

  CO2、相对湿度、温度和环境压力模块化探头

EE872专为恶劣和苛刻的环境应用而研发,如农业、畜牧养殖、孵化器、恒温箱或绿色大棚;测量范围高达5% CO2 (50 000 ppm)。

CO2 和温度  (T)的多点校准功能使其在-40到60 °C的全量程范围内都具有 出色的测量精度,是农业或者室外应用的理想选择。

EE872采用了E+E单光源双光束红外线测量技术,可以自动进行光源老化补偿,并具有较高的抗污染能力,从而保证了产品卓越的长期稳定性。传感器的自动补偿功能使其具有出色的CO2测量精度,并不依赖于温度、海拔或天气等环境条件。

EE872配备的加热型测量模块使其可应用在高湿和结露环境中。在污染环境中,IP65防护等级的外壳和可更换的过滤器为其在污染环境中的应用起到了保护作用。独特的过滤帽设计使其可用在周期性H2O2 灭菌环境中。

CO2 测量可同时选择电压输出和电流输出,或者带Modbus RTU协议的RS485数字输出。

用户可通过免费的配置软件EE-PCS和适配器对产品进行设置和调整。

The EE872 from E+E Elektronik measures the CO2 concentration up to 5 % (50 000 ppm) as well as relative humidity, temperature and ambient pressure. Additionally, the 4 in 1 probe also calculates the dew point temperature. It is perfectly suited for use in harsh and aggressive environment, such as agricultural applications. The active pressure and temperature compensation ensures a very high CO2 measuring accuracy. A heated probe version is available for CO2 measurement in high humidity applications.

For Harsh Environmental Conditions

The CO2 measurement is based on the pollution-resistant E+E dual wavelength NDIR measuring principle. It automatically compensates for aging effects, which leads to outstanding long-term stability. Thanks to the E+E proprietary coating, the humidity sensing element is suitable even for aggressive and corrosive environment. The robust IP65 stainless steel or polycarbonate enclosure as well as various filter caps optimally protect the sensing module from contamination. The probe is therefore particularly suitable for use in agriculture, for example in life stock barns, hatchers, incubators and green houses.

High Measuring Accuracy

The multi-point CO2 and temperature factory adjustment ensures high accuracy over the entire working range of -40...60 °C (-40…140 °F). Due to the active pressure and temperature compensation with on-board sensors, the EE872 offers a particularly high CO2 measuring accuracy, independent of altitude or environmental conditions.

Heated Probe Version for High Humidity

The heated version of the EE872 can be used especially for CO2 measurement in high humidity or condensing conditions. The heating prevents condensation on the sensing module, which makes the probe work reliably even in the high humidity range. Additionally to CO2 and pressure, the heated version provides the dew point temperature.

Easy Service and Configuration

The EE872 has a modular design. The pluggable sensing module can be replaced in just a few seconds without requiring any tools. Also the filter caps (PTFE or catalytic for H2O2 sterilization) can be quickly replaced if necessary. Configuration and adjustment of the EE872 can be easily performed with the free configuration software together with an optional adapter cable.

Analog or with RS485 Interface

The CO2 measured data is available simultaneously on the analogue voltage and current outputs. Depending on the version, the EE872 with RS485 interface also provides the data for relative humidity (RH), temperature (T), pressure (p) or dew point (Td).
