U3430 - Compact thermometer – hygrometer - CO2
This model is designed to measure temperature, relative humidity, dew-point temperature and the concentration of CO2 in the air by internal sensors. Barometric pressure can be measured as absolute or recalculated to sea level. No additional probes or sensors can be connected. It is characterized by a simple and compact design and a relatively long response in the measured quantities, compare to model with external probes. The sensors are located under the grid on the front and side of the unit The device is suitable for measuring in places where there is no rapid change in temperature or relative humidity, and there is no condensation of water vapours. The device is placed directly in the measured space, Accupack in the device can be charged. As the internal battery creates a parasitic heat during the charging period, the measurement accuracy may be affected by up to 1 º C. In battery mode, this model has significantly shorter battery life than models without CO2 concentration measurement. For this reason, the measurement of CO2 concentration does not occur as often as the measurement of other variables. By default, this is 2 minutes with the option of extending up to 10 minutes (option available in the COMET Vision SW). We recommend calibration of the relative humidity and temperature in the laboratory with the unscrewed bottom lid of the box to allow the air to flow from the back of the electronics. When air flow in the range of 0.5 - 1 m/s perform reading after about 4 hours. Due to low IP20 protection, this device is not suitable for
dusty or water-borne areas.
