The OM-DVTH temperature/relative humidity data logger with display is an easy-to-use, versatile device which can be used for a wide range of logging applications. The OM-DVTH records and instantly displays trends for temperature, humidity and dew point. With the OM-DVTH you can monitor real time measurements for instant environmental conditions.
When you’re ready, download over 40,000 data points to your PC for further analysis. Data logging has never been this visual. The OM-DVTH is capable of sampling as fast as once per second or as slow as every 18 hours. A total of 43,344 temperature measurements can be stored in the data logger memory if only temperature is measured, or 21,672 measurements for temperature, humidity and dew point if all three parameters are measured.
Easy-to-use Windows software is included with the OM-DVTH. The software is a full-featured program that allows you to set up all data logger functions including sampling rate, logging duration, start mode, logging mode, and high and low temperature and relative humidity alarm values. Once data has been logged, the program then allows you to download data from the logger, plot the data and export the data to an ASCII text or Excel file format for further analysis.

Good performanceThis is our 3rd unit. A bit pricy for the certified model.
Can custom software be made to interface with this product? Does it work over a virtual COMM port?
Asked by: Fancypants
API is not available for this unit, the only way to communicate with it is with the provided software.

The user manual does not give the dimensions of the sensor for the OM-DVTH. Could you please provide these or a drawing if available? I am also looking for the diameter of the cable that joins the sensor to the display module.
Asked by: Mr G
Thank you for your question. The OM-DVTH sensor is inside and vented to atmosphere. It is not an external sensor. Please look at RHXL3SD which is a logger with external temp/rh probe.

Is there a driver available for Windows 10?
Asked by: Lanny
I was able to get the driver to work finally. My computer was not looking in the right folder for the driver. Once I directed it to look in the Omega folder it found it, and I can use the software on a system running WIndows 10.
