Categories: ,
High-precision Comet T8148 sensor for HVAC and energy management. Features dual 4-20mA outputs, NDIR dual-wavelength technology, and a switchable LCD for reliable indoor air quality monitoring.

COMET T8148  | INTERIOR CO2 & TEMPERATURE TRANSMITTER (4-20mA)

A standalone, high-precision indoor \(CO_{2}\) monitor featuring an integrated acoustic alarm and visual LED indicators for air quality management. The Comet U8415 is an advanced indoor monitor designed for professional air quality assessment, specifically targeting \(CO_{2}\) levels in various occupied spaces.

  • CO2 – carbon dioxide level and temperature sensor.
  • Large dual line LCD is possible to switch off.
  • Computerized design ensures long term stability and fail indication.
  • Transmitter is designed for use in non-aggressive environment.

 

COMET T8148  | INTERIOR CO2 & TEMPERATURE TRANSMITTER (4-20mA)

The Comet U8415 is engineered to monitor carbon dioxide concentrations using a maintenance-free NDIR dual-wavelength sensor. This technology ensures exceptional long-term stability by compensating for the natural aging of the infrared source. The device provides immediate feedback via a multi-color LED and a built-in buzzer when \(CO_{2}\) levels exceed pre-set safety thresholds. It is designed for wall mounting and is powered by an external 5V adapter (USB-C), making it a reliable choice for permanent air quality surveillance.

PRODUCT USES:

  • Optimizing ventilation in schools and daycare centers.
  • Monitoring air quality in office buildings and conference rooms.
  • Ensuring occupant comfort in hospitals and healthcare facilities.
  • Maintaining safety in residential buildings and theaters.
