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 performance
This is our 3rd unit. A bit pricy for the certified model.

Is there a driver available for Windows 10?
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.

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. Thanks.
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.

My computer is looking for a driver? Is there one available. Win7
Here is link to ftp site to download OmegaLog1503.zip. The driver is part of the install.

thank you.

Is there a bracket or holder available from Omega that this device can snap into? There is only one small mounting hole on the back for hanging and this doesn't serve our application of this device well.
Unfortunately, there is no bracket or holder available for mounting.

Could you provide a response time spec? We have 7 of these units and they have taken 2+ hours for a unit to reach the proper temp/RH in our calibration chamber. It can take hours to read within OMEGA's specified accuracy for temp/RH range
Thank you for your question. We will require more information to help on this question, please email the DAS team at DAS@OMEGA.COM
