T5000 Airestat CO2 &Temperature Transmitter
原装进口美国GET5000系列二氧化碳温度传感器变送器
The Telaire® T5000 series Airestat™ CO2 and temperature transmitter is a low-cost wall-mounted sensing solution for demand-controlled ventilation.
The Airestat provides an intuitive VLI (Visual Limit Indicator) display for CO2 thresholds, a passive temperature output (20k thermistor), and a standard analog 0 to 10 volt signal to maintain air quality in enclosed spaces (such as school classrooms, offices, gymnasiums and theaters).

* Note: Automatic Background Calibration, or ABC Logic, is a patented self-calibration technique designed to be utilized in applications where concentrations will drop to outside ambient conditions (approximately 400 ppm) at least four times in a 14-day period, typically during unoccupied periods. Full accuracy is achieved after two weeks of operation.
