CO2 transmitter TKR100 series
Hosansho Co., Ltd.
About This Product
■Measurement principle/product overview
There are methods to detect CO2 concentration in the atmosphere, such as NDIR, solid electrolyte sensor, and photoacoustic spectroscopy (PAS), but generally an analyzer called NDIR (Non Dispersive Infrared Gas Anaryzer) is used. In the case of CO2 molecules, it has the property of selectively absorbing infrared rays with a wavelength of 4.26 microns. When CO2 molecules are present in high concentrations, they will be absorbed more strongly. NDIR takes advantage of this property. When the gas to be measured is passed through a tube (cell) with an infrared light source and an optical sensor element fixed at both ends, at low concentrations the attenuation of the incident light is small, and at high concentrations the attenuation increases.
■Applications
・For CO2 concentration control in vinyl houses and plant factories
・For air conditioning management
・As a guide for ventilation in offices and facilities, etc.
・Incubator, for research
・For detecting refrigerant gas leaks in refrigerators
・For detecting residual concentration in CO2 fire extinguishing equipment
■Features
・Displays CO2 concentration in real time on the LCD display.
・Measurement range is 0 to 10,000ppm (TKR100L/LR), 0 to 50,000ppm (TKR100LR05).
-Equipped with an automatic calibration function that automatically corrects deviations.
- Analog output can be selected from DC4mA to 20mA/DC2V to 10V/DC0mA to 20mA/DC0V to 10V.
・TKR100LR/LR05 has 1 relay contact output (contact capacity 1A/AC125V), which turns ON when the set alarm value is exceeded.
-Hysteresis can be provided for ON/OFF of the relay to prevent unnecessary chattering.
(If the relay turns on and falls below the threshold, it will turn off at a value further reduced by the hysteresis)
-Threshold and hysteresis can be set freely in 50ppm increments.
