PCE-GA 70 Air Quality Meter

PCE-GA 70 Air Quality Meter Measures CO2 ( carbon dioxide) , temperature and humidity PCE-GA 70 air quality meter is an exceptional handheld device that measures and checks air quality, and the content of carbon dioxide, humidity and temperature of interiors. This air quality meter is ideal for heating, air and climatology professionals that need this device for detecting air quality indoors, for testing air ventilation systems in schools, offices, factories and hospitals. The PCE-GA 70 air quality meter uses a sensor to define the content of carbon dioxide, air temperature and relative humidity. It can store more than 20, 000 readings with a time stamp allowing to transfer data to a computer. The sensors used for testing air quality are the subject of other requirements, different to the requirements for industrial or scientific laboratory use. As such, we give priority to the properties of the sensor such as durability, low level maintenance and low energy consumption. The PCE-GA 70 air quality meter meets certain requirements with its NDIR sensor. The measurement of non-dispersed infrared ( NDIR) measures accurately and has a measurement range of up to 6000 ppm. A new method of measurement ( mentioned here) is developed for the analysis of air quality: the source of infrared is controlled by a brief pulse of radiation that minimises the consumption of energy. The pyro-electric detector is designed and adapted to allow the analysis of the impulse, such as a functioning pulse like that of a conventional chopper. • Large CO2 measurement range up to 6000 ppm • Triple LCD for CO2, relative humidity and air temperature • The NDIR sensor for CO2 is maintenance free • Automatic and manual data storage for up to 20, 000 readings • Data Hold and memory for minimum and maximum values • Stored values can be read on the display • Alarm and time settings • RS-232 port with software included • Backlit display • Safe and easy to use Technical specifications Measurement range for CO2: 0 to 6000ppm CO2 Accuracy: ± 3% of reading or ± 50 ppm Resolution: 1ppm Temperature: -20 to 60º C Accuracy: ± 0.5º C Resolution: 0.1º C Air humidity: 10 to 95% r.h.
