The OM-90 Series are portable, battery operated, temperature (OM-91) and temperature/humidity (OM-92) data loggers. The OM-90 Series data loggers offer accurate and repeatable logging for temperature and relative humidity. Temperature is measured to an accuracy of ±0.3°C over the range of 5 to 60°C (41 to 140°F) and ±2.0°C over the full range of -30 to 80°C (-22 to 176°F). Relative humidity is measured to an accuracy of ±3.0% RH over the 20 to 80% RH range and ±5.0% RH over the 0 to 100% RH range. Both temperature and relative humidity are logged at a user configurable logging rate which is software selectable.

These data loggers are ideal for transportation applications where it is necessary to document that the material in-transit has stayed within particular environmental limits. High/low alarm limits can be set above or below which LED indicators will be activated so that the user can become aware that the desired transportation conditions have been exceeded.

Each data logger can be assigned a 16 character name. This can be helpful in applications where multiple data loggers are used and there is a need to distinguish between them (for example based on location).

The data logger includes a very easy to use software application. The application is used for configuration of the logger, extraction of logger data, graphically viewing data, spread sheet analysis of data and saving data to file (typically in comma separated value CSV file format) for third party applications such as Microsoft Excel. The graphical user interface is completely intuitive in terms of configuring new devices and extracting data from a field device. When the user has multiple devices requiring the same setup then a logger setup from a saved configuration file can be preloaded into the application to help expedite the process and ensure all loggers get setup identically. The application does not require any driver installations to connect to the data logger. Just install the software, run it and then connect the data logger.

Rated 5 out of 5 by from Stupidly simple to use Bought this to monitor T and humidity in my basement for suitability of wine storage. Very easy to use, super simple, data output is straight forward and versatile. Easy-peasy

Rated 4 out of 5 by from Great product when you can find the software I have had this about 45 days and it has preformed well. DO NOT lose the software disk that the product comes with. You will NEVER find the software on the omega site if you need to download it again

Rated 1 out of 5 by from Impossible to use. Cannot download data from unit to software. Unit will not consistently connect. Software will not work with Windows 10.

Rated 5 out of 5 by from Compact - Easy to Use The mini CD that came with the product did not work. However, one call to Omega and tech support emailed me the software. Once installed, the setup was incredibility easy. I set the unit up, shipped it to my customer with instructions to install and to hit the small button on the right of unit to activate. 2 weeks later picked the unit up. Downloading the data and transferring to Excel was seamless. Highly recommend.

Rated 5 out of 5 by from Works Perfect! I purchased 2 of these about 2 months ago and they work great. I needed them to monitor temps in 2 tenant spaces.I have been using temp scribes from Grainger in the past and they are a few hundreds each. then you have to purchase chart paper and replace pencils. These are digital and can create a professional looking report to share with others if needed. For the price you can't beat them.

Rated 1 out of 5 by from disappointing 1. I was not able to download the software. The quick start guide had a web address for the software that you cannot go to. I had to request help in an email. 2. Now that I have the software, the software does not connect to the om-92. No blue square even though my computer shows the om-92 connected and the software is open. Why is that? No troubleshooting guide. 3. I go to replace the battery, which the quick start guide says is a CR2450, so I buy a CR2450. When I get home and take the cover off, the battery is a CR2032 inside. Why does your guide say CR 2450 when your instrument uses CR2032?

Are these NIST recognized calibrated? Can they be calibrated on a routine basis?

Asked by: Kurt1234
Hello Kurt Yes they can be NIST calibrated, the part number would be OM-92-NIST. We do recommend them to be calibrated at least once a year, depending on usage.

- lead time? - How do we read the measurement on a automation plc (analog signal 0-10V or 0-20mA or 4-20mA etc...) or is it direct modbus serial or tcp connection or other? - How often does it need calibration? - what is the life span?

Asked by: Marcio
Hello Marcio This device strictly works via USB on its own proprietary software, it does not have tcp or modbus capability.

Is the OM-92 RoHS compliant?

Asked by: Daniel at Atia
The RoHS2 status of this part number has not yet been determined. OMEGA is diligently working to determine the RoHS2 status of this product, but we are still waiting to receive information from our suppliers. The status of this product may change in the near future so please check back soon. Thank you.

After connecting OM-92, Windows prompt to automatic USB driver installation and then it says "device is ready to use". But the software does not detect and illuminate the connection icon and I cannot 'read' or 'configure' it. How can I make this work?
