DTH Sense-Aire Mk.2

Site under construction....

Building on the success of the original award winning DTH Sense-Aire, the DTH Sense-Aire Mk.2 Temperature and Relative Humidity meter is the latest version. It is a feature rich device designed to be easily configurable and low cost to suit the needs of most applications.


The DTH Sense-Aire Mk.2 is a completely new design and has been designed to be low cost and robust. It uses the latest in semiconductor technology and features a highly accurate, factory calibrated sensor with a very fast response time. The unit has a unique LED based display to display the relevant data. Unlike LCD displays, the LED display is viewable from a large distance. This feature was the most popular feature of the original DTH, especially in laboratory environments.


Just some of the potential applications for the DTH Mk 2 include:

  • Greenhouses
  • Farming
  • Mining
  • HVAC
  • Pharmaceuticals

The Device

The DTH Mk 2 is a highly customisable device that is programmable through USB and an easy to use windows application (terminal based version in the near future). It features a number of different options:

  • Fully configurable high visibility LED display, alternating between configured readings
  • Two completely configurable powered 4-20mA current loop outputs (configurable between 0 and 24mA)
  • Two general purpose LEDs that can be configured for a number of different uses, including threshold and window alarms on any of the variables
  • Two general purpose open-drain MOSFET outputs that can also be configured for a number of different uses and simple control (up to 40V at 2A)
  • Addressable RS-485
  • Two different power supply options: mains power or externally powered by a 9-28V DC supply
  • Custom sensor probe lengths are available on request
  • Wall mountable IP65 housing

Configuration Utility Software
The configuration software has been designed to allow the user to easily configure the DTH to his/her requirements. It provides easy and intuitive control over the different aspects of the DTH. It also provides descriptions of each of the various fields.
