HT1D Series Humidity Temp Duct

DESCRIPTION

The HT1D Series is designed with both the engineer and field technician in mind. The HT1D Series combines excellent stability with reliable operation in 2% or 3% RH accuracy options. Optional temperature transmitters, RTDs and thermistors add further flexibility when ordering. The standard LCD and field replaceable elements make the initial installation and future service a breeze.

• 2% or 3% RH versions with field replaceable sensor
• Switch selectable 5V/10V and 4-20mA RH/T transmitter outputs
• Thermistor outputs for temperature optional
• Field calibration. LCD and push-button menu allows easy adjustment of calibrated RH value as needed to maintain certification.
• Field replaceable sensor—without disturbing conduit
• On-board temperature compensation for RH. Eliminates temperature coefficient errors and achieves excellent measurement accuracy, high repeatability, and offset stability.
• State-of-the-art testing facilities. Certification options: 8-point (NIST traceability—consult factory)
• Industry-leading 7-year warranty/ 2-year replaceable element warranty
•  APPLICATIONS
  
  • HVAC room humidity and temperature measurement and control
  • Replaceable element is ideal for difficult environments such as swimming pools
  • Facilitating compliance with ASHRAE 62.1 standard for air quality
  • Indoor air comfort and control in HVAC systems
  • Maintain healthy air quality, minimize mold and other contaminants
  • Museums, hospitals & other critical environments
  • Offices, conference rooms, & indoor public areas
  • Industrial process control environments
  • One side of transformer, secondary is connected to signal common. Dedicated transformer is recommended.
  • Time for reaching 63% of reading at 25° C and 1 m/s airflow.
  • Long term exposures to conditions outside normal range at high humidity may temporarily offset the RH reading (+3%RH after 60 hours.)
  • 15-30VDC/24VAC power supply voltage required for 10 volt output.
