Visualiser la température et l'humidité avec un navigateur Web
L'émetteur OMEGA™ iTHX-SD vous permet de contrôler et enregistrer la température, l'humidité relative et le point de rosée avec un réseau Ethernet ou Internet sans devoir utiliser un logiciel spécialisé, seulement un navigateur Web.

Le OMEGA™ iTHX-SD transmet les données aux pages Web actives pour afficher les lectures en temps réel et les graphiques de température et humidité. Vous pouvez également enregistrer les données en format standard pour pouvoir les utiliser dans un tableau ou un programme de saisie des données tel que Excel ou VBX (Visual Basic). Le graphique virtuel sur la page Web est un applet JAVA™ qui enregistre un graphique Applet sur un réseau local ou Internet en temps réel. Avec le système OMEGA™ iTHX-SD vous n'avez plus besoin de consacrer votre temps et votre argent à vous renseigner sur un programme de logiciel propriétaire pour pouvoir enregistrer les données.

Relais alarme
Le OMEGA™ iTHX-SD possède deux relais 1,5 A. Avec la page de réglage en ligne, les deux relais peuvent être programmés à n'importe quelle combinaison de température ou humidité, et des points de consigne hauts ou bas. Les relais peuvent également être programmés à rester verrouillés et d'attendre une remise manuelle si la limite est surpassée.

Batterie de secours
Le OMEGA™ iTHX-SD est fourni avec un adaptateur universel 100 à 240 Vca. Une pile alcaline standard 9 V (comprise aussi) permet le périphérique de stocker des données pendant une durée de 2 jours sans alimentation ac externe. Au cas où le réseau Ethernet tomberait en panne, l'enregistrement des données ne sera pas interrompu.

Graphiques ajustables
Les graphiques sont totalement réglables en temps réel. Par exemple, le graphique peut afficher une minute, une heure, un jour, une semaine, un mois, ou un an. La température peut être tracée en utilisant la gamme complète (-40 à 124°C, et 0 à 100% HR) ou une plage définie telle que 20 à 30°C.

I have iTHX-SD-2, M21210492. With a humidity probe tip of iTHP-2-DB9. the probe is using an RS232 to connect the display reader. Can I add and RS232 to RS232 extension to extend it? Or do I need to buy a probe with a longer neck?

Asked by: WasCKtoYF
Thank you for your question. Yes you can extend the cable but the accuracy may be affected.

When on a yearly calibration cycle, the unit is found to be out of tolerance when sent out for certification, can adjustments be made to bring it into tolerance, or is it “not adjustable” like most Temp/RH recorders.

Asked by: Roman
It is not adjustable

The iTHX-D3 used a separate End Character for Temp, Hum and Dew Point. We knew which one was being transmitted to the PLC based on that end character. Now the D3 has been replaced by the SD and it does not allow us to do this. What options do we have now?

Asked by: MikeS
The SD version does not have the option for the end character that is correct. However management has reinstated the D3 unit so you can contact customer service and return the SD model and order a D3 to fit your needs.

After disabling probe 2 I am getting HT Probe 1 Error. Is the sensor defective?

Asked by: Jyotirmoy
Hello, thank you for your question. If you already saved the configuration for 1 sensor only, then something as a lose connection could be the reason for this message. Please make sure the sensor is fully inserted into the socket. If this is not the case, please contact our Data Acquisition experts for further troubleshooting. The email is or you can give us a call and ask for DAS technical support.

I have 2 iTHX-SD devices that I placed in DHCP mode by pressing °C/°F and TIME/IP button during power-on. Both devices now have same MACID which is NOT the ones that were assigned during manufacture. MACID's are supposed to be hard coded. Why this happen?

Asked by: Susan1
A MAC address should never change but sometimes (rarely) they do. We haven't been able to narrow down the reason why it happens, but we do have a solution. There is an unlisted command string to overwrite the MAC by telnetting into port 2002: ‘s –MC[macaddr]’ The ‘s’ must be lowercase and the ‘MC’ must be uppercase. Examples: s –MC00:03:34:00:c3:4e s –MC00:03:34:00:B9:B6 c (the “c” confirms the change)” If you have more questions on this, please send us an email to for your specific case. Regards.

According to the Product Spec sheet for Omega iTHX-SD Chart Recorders, regarding "Sensor and Calibration" it states "It is not necessary to take the iTHX-SD out of service for routine calibration." Does this mean that routine calibration is not required?

Asked by: MichaelVale
We sell the pre-calibrated probes, you could order them three or four weeks before the ones you have expire (that is typical lead time for you), that way you do not have to put your devices out of service. Thank you.

Can the iTHX-SD be used as a handheld device to quickly take readings at multiple locations? Ultimately we plan to position the device in a permanent location and connect it to our network but I'm wondering if the device can also be used as a handheld.

Asked by: Matt524
Hello I am sorry it is not designed as a hand held device you cannot start and stop the device except using a PC through the network to send commands.
