TSP-CO2 Series

Product catalog summary

Overview
The TSP-CO2 Series is a versatile carbon dioxide detector designed for real-time monitoring and control of CO2 levels, with optional temperature and relative humidity (RH) detection. It features a Non-Dispersive Infrared (NDIR) CO2 sensor with patented self-calibration for enhanced accuracy and reliability.

Key Features

Real-time CO2, temperature, and RH measurement capabilities.
NDIR infrared CO2 sensor with self-calibration, offering up to 10 years of sensor life.
Selectable PID control output for CO2 measurement.
Optional OLED display for CO2, temperature, and RH readings.
RS485 communication interface supporting Modbus or BACnet protocols.
Optional relay output for controlling a fan or CO2 generator.
3-color LED indicator for CO2 level ranges and operational status.
Buzzer alarm available for models with relay output.
