Aecl Temperature and Humidity Transmitter (For High Humidity Environment, Duct-mount, Outside Air, Separated)

Product catalog summary
Overview
The AHT-503H series is a temperature and humidity transmitter designed for high humidity environments. It features a high accuracy dual function sensing element and a metal sintered head design to minimize condensation risks. This makes it suitable for use in environments such as wine cellars, mushroom farms, greenhouses, warehouses, plant factories, poultry farms, and server rooms. An optional LCD display is available for on-site monitoring.
Features
  • Rapid response time with high stability and accuracy.
