Comet T3413D – Temperature and Humidity Duct Mount Transmitter with RS485 Output

• Temperature and humidity duct probe with RS485 output
• Dual line LCD screen (display can be switched off)
• Temperature measuring range: -30 to +125 °C
• Humidity measuring range: 0 to 100% RH
• Dew point measuring range: -60 to +80 °C

The Comet T3413D is a temperature and humidity transmitter with a duct mount. The temperature and relative humidity sensors are located on a 150mm stem. Measured values are also converted to dew point temperature, absolute humidity, specific humidity, mixing ratio, and specific enthalpy.

The measured and computed values are displayed on the dual line LCD screen. The first line displays temperature. The value displayed on the second line is selectable between relative humidity and computed value. It is also possible to display both readings with cyclic overwriting in intervals of four seconds. It is possible to switch off the display entirely. 

The transmitter is designed for air-conditioning duct mounting – metal stem fixed by means of the optional gland or installation flanges PP4 or PP90. Please note, the glands and flanges are sold separately. The sensors are non-removable instrument parts. It is not recommended to use the device for long periods of time under condensation conditions. This could cause condensation inside the sensor’s cover, from which water phase cannot escape easily.
