Description
Les séries OM-140 sont des enregistreurs de données de température / humidité compacts et à batterie, capables de consigner sans surveillance (enregistrement) de la température ambiante et de l'humidité relative (HR) d'un environnement pendant des jours, des semaines ou des mois.L'enregistreur de données OM-144 peut également mesurer et éventuellement enregistrer des températures de surface vérifiées par un technicien à l'aide du thermomètre à infrarouge intégral (IR) de l'unité. En outre, ces unités peuvent également calculer et afficher des niveaux d'humidité absolus en unités de grains par livre (GPP) ou g / kg. Aussi appelé ratio de mélange, GPP est une mesure d'humidité plus utile que la RH pour les restaurateurs de dommages à l'eau. En utilisant RH seul, un restaurateur pourrait involontairement introduire l'air humide - avec une faible HR mais un GPP élevé - pendant la phase de séchage d'un travail
L'enregistrement des données peut être démarré ou arrêté en appuyant sur un bouton de l'unité, ce qui élimine la nécessité d'apporter un ordinateur portable sur le site de travail. Une fois qu'un journal de données a été capturé et stocké, il peut être téléchargé sous la forme d'un fichier .txt sur n'importe quel PC exécutant le système d'exploitation Windows® XP / 7 ou 8 après avoir branché l'enregistreur de données dans l'un des ports USB de l'ordinateur. La mémoire flash interne de l'enregistreur de données est suffisamment grande pour stocker 16,300 paires de lectures de température et de RH ou pour le modèle OM-144 près de 10 000 ensembles de température de HR, de température ambiante et de température de surface. Le produit comprend un mini-disque avec les pilotes nécessaires pour interagir l'unité avec l'ordinateur, ainsi qu'un logiciel qui peut afficher un fichier journal de données sous forme de tableau ou de graphique et / ou l'exporter vers Microsoft Excel. L'exportation vers Excel est recommandée pour les tendances et les analyses sophistiquées des données sur l'humidité et la température et la détection facile des excursions inattendues.

So Far So GoodBeen using two of these units for the past couple weeks and they are performing well. Temperature accuracy is as advertised (they give the exact same reading to the tenth of a degree C and these temps match other accurate devices I have. The relative humidity values vary by 0.5%, but this is in the advertised range. Very easy devices to set-up and to remove data..

Great value. Excellent product.After 2 weeks of testing I'm going to give the OM-141 4 stars. If I could give it a 4.9 I would do that. I've only had one problem so far and it is not a showstopper.
I initially set the sampling rate to 30 seconds to collect and simulate a collection of many data-points, way more than we need), and in one week it had collected more data than the software seemed to download without a 'timeout' error being thrown. There needs to be a way to set the timeout value. When I put these in production we will set the sample rate to 12 hours, more than adequate for our needs, but I'd like to only download the data when I receive an alarm. if my freezers are doing well, I can foresee a timeout occurring if the time between downloads is sufficiently long to record a bunch of data-points.
In device setup, the sensitivity of the slider to set High/Low points is way too sensitive and I end up setting bounds slightly different from what I want. Not a big deal, but frustrating.
As I explore the software I am continually surprised by how many features are available. The best advice I can give to new users of the products is to "Read the **** manual".
Another problem we experienced had nothing to do with the device, but rather it was cockpit trouble: when we placed two of the device, I forgot to hit the start-button. I don't know what the solution would be on the OM141 to protect us from operator (me) error. Add that to your "would be a nice feature to have" list.

Thermometer and RH with data log portableIt takes too long to changes in temperature. I regret purchase. Software to retrieve data is troublesome as well. I don’t recommend it.

OK for low budgetI wish I had purchased the 143. The 141 is hard to tell if it's Power On or Not.

Frequent software malfunctionsPurchased 4 of the base models of the OM-141. They worked the first time, well within advertised accuracy. Additional setups and data extraction work 10% of the time. Package software often has timeout errors even with small <100 data point sets. Frequently wipes data off devices for no reason as well. Manual and setup DVD provided no explanations for these peculiar cases

Great out the boxTested over and hour and checked. So far so good. Fixing to put them to work on mold lawsuit home and will follow up after recording for three weeks
The OM-140 series (141;142;143 and 144) are they suitable for the monitoring of ventilation temperature into the undergound mines ?

I use Linux, not Windows. A few Qs: 1. What is the default setting for sampling rate? 2. Will the device appear as a storage device if plugged into a Linux kernel? 3. If yes to 2., will the .txt data file appear on the device? Thx
Asked by: Cam W
Thanks for your questions. Unfortunately, the OM-141 (or the OM-HL-SP) will not support Linux since both logger’s software is designed for Windows. However, we can recommend the product OM-HL-SP, the max logging rate is 1 sec and the default is set to 60 secs. Please contact us anytime with further questions.

Regarding the OM-141 temperature/RH datalogger software, is it available for download as an alternative for laptop PCs without a CD drive?
Asked by: AnthonyM
Thank you for your question. ELUSB V2.04 software is available as a download from OM-141 product page. Just scroll down under manuals and downloads there will a software download.

I see the data sheet says these work with Windows® XP/7 or 8 operating system. Will these work with Windows 10?
Asked by: CAVB
At the time it is only tested to work with operating systems up to Windows 8

Are these NIST calibrated, because the product details do not mention that. If not, what would be the cost of getting it calibrated?
Asked by: Krutarth
Thank you for your question. The OM-141 is not available with Nist Please consider OM-EL-USB-2-PLUS which is available with Nist. I have attached 2 links from our website with details and pricing.

Would this device be compatible with any type of probe . we are currently loooking for a device to measure compost temperature and humidity via some kind of probe.
Thank you !
Asked by: Marc Andre Lauzon
Hello Marc
As long as it is one of the following thermocouple types: J, K, T, E, R, S, B, C or N
Also the probe will need either a standard round prong or mini blade type connector attached at the end so it can connect to the transmitter.
