Notes for the Use of LARK-1 Infrared Sensor (1)

The LARK-1 series products of Normalized Core Company have been released for nearly four months, and have received close attention from users of all walks of life. We collect some technical questions from customer feedback. In this article, I focus on answering them. The purpose is to shorten the user's R&D time, save R&D and maintenance costs, and reduce the technical risk of use.

Response of LARK-1HR i-C4H8 Infrared Sensor to Several Common VOCs

With the more and more stringent supervision of VOC emission from industry, the demand for VOC sensors in instrument industry is becoming more and more urgent, and the demand is also getting higher and higher. Taking Hebei Province as an example, the environmental protection department requires that the VOC online monitoring equipment for organized emissions must be installed in place by June 30, 2018.

Basic Characteristics of LARK-1HRCO

Since the release of the LARK-1CO infrared gas sensor, the market feedback has been good. According to the needs of many customers, we have released an improved version of LARK-1HR CO, which means the abbreviation of High Resolution with high resolution.

LARK-1 Modbus Communication Converter

In March this year, Nordson launched a LARK-1 Modbus communication converter based on RS485. The model is "MODBUS COMM-CONVERTER" and the order number is "001-3010-000". The function of the converter is to transform the text-based communication protocol of LARK-1 series sensors into Modbus RTU protocol which is widely used in industry.

LARK-1i-C4H8 Infrared VOC Sensor

VOC is the abbreviation of volatile organic compounds, which is the focus of monitoring in environmental protection industry. The reason why it should be monitored is that VOC, CO, NO, NO2 will produce ozone O 3 after a series of chemical and photochemical reactions under the condition of light. Although the low concentration of O 3 (< 0.1ppm) does not do much harm to human body, it is one of the main reasons for the frequent occurrence of respiratory diseases in areas with serious pollution and high ultraviolet irradiation. The concentration of O 3 can reach hundreds of ppb (1 ppb is 0.001 ppm) during the daytime.

Cross-interference of LARK-1 CO with high concentration of CO2

After the release of LARK-1CO, many customers used it in the field of flue gas emission applications. LARK-1CO is indeed a cost-effective tool for flue gas analysis.

Long-term stability of LARK-1 CO sensor 2017-12-26

The infrared LARK-1CO sensor manufactured by Normalized Core is one of the largest transducers in the world. It is widely used in flue gas analysis. The common range is 10 000 ppm and the special range is 10% Vol. Infrared sensors have so far been unable to achieve the same accuracy as electrochemical sensors.

LARK-1 CO2 Infrared Sensor

In September of this year, Northcore released a new product, LARK-1 CO2. Infrared CO2 sensor is a very common sensor, so what are the characteristics of Normalized Core products? What special applications can it use?

LARK-1 CO2 100PPM Infrared Gas Sensor

Response of LARK-1 CH4 Infrared Sensor to Various HC Substances

Since the release of the infrared gas sensor LARK-1 CH4 with Normalized Core, it has attracted wide attention. It also has sales performance and many customers.
