# Data Logger, Temperature & Humidity ![Product image](https://novapart.co/image/farnell:3805963/) **URL**: https://novapart.co/products/ITHX-W3-5/data-logger-temperature-humidity **SKU**: ITHX-W3-5 **Manufacturer**: OMEGA **Price**: €452.3600 **Stock**: 10+ **Lead Time**: 47 days (indicative) ## Specifications | Parameter | Value | |---|---| | Svhc | Lead (04-Feb-2026) | | Product Range | iTHX-W3 | | Data Logger Type | Temperature & Humidity | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:3805963/) ## _**Temperature and Humidity Virtual Chart Recorder**_ ## _**iTHX-W3 Series**_ **FCC-B Optional[†]** ## **Web Server** **Alarms by Email or Text Message Accurate Readings Data Logging No Special Software Required** ## **View Temperature and Humidity with a Web Browser** The OMEGA[®] iTHX transmitter lets you monitor and record temperature, relative humidity, and dew point over an Ethernet network or the Internet with no special software except a web browser. The iTHX serves active web pages to display real-time readings, charts of temperature and humidity, or log data in standard data formats for use in a spreadsheet or data acquisition program such as Excel or Visual Basic. The virtual chart viewed on the web page is a JAVA™ Applet that records a chart over the LAN or Internet in real time. With the iTHX, there is no need to invest time and money learning a proprietary software program to log or chart the data. ## **Adjustable Charts** Chart scales are fully adjustable on the fly. For example, the chart can display one minute, one hour, one day, one week, one month or one year. Temperature and humidity can be charted across the full span [-40 to 124°C (-40 to 254°F)], and 0 to 100% RH or within any narrow range such as 20 to 30°C (68 to 86°F). ## **Award-Winning Technology** The OMEGA iTHX is simple to install and use, and features OMEGA’s award-winning iServer technology that requires no special software except a web browser. The iTHX connects to an Ethernet network with a standard RJ45 connector and sends data in standard TCP/IP packets. It is easily configured with a simple menu using a web browser and can be password protected. From within an Ethernet LAN or over the Internet, the user simply types the IP address or an easy-toremember name such as “Cleanroom5” or “Server Room” in any web browser, and the iTHX serves a web page with the current readings. ## **Email Alarms** All OMEGA iTHX models that are on a LAN that is connected to the Internet can trigger an alarm that can be sent by email to a user or a distribution list anywhere in the world, including text messages to cell phones and PDA’s. ## **Link to Web CAM or IP Camera** The web page includes a link to a “web cam” or “IP camera” (not included). If you get a message about an alarm condition, you can quickly click on the link to view the actual scene over the Internet. _**†** Refer to next page for NIST calibration ordering information._ **==> picture [243 x 195] intentionally omitted <==** **----- Start of picture text -----**

## i ®™ Server ## **Sensor and Calibration** The iTHX transmitters come complete with a temperature and humidity probe for measurement of a single location. OMEGA offers a choice of industrial probes in 2" (with a 3' cable) or 5" length (with a 10' cable) instead of the commercial wand style probe which is designed for ambient indoor applications. It is not necessary to take the iTHX out of service for routine calibration. The temperature/ humidity sensors are interchangeable and can be **iTHX-W3 iServer** replaced for about the same **MicroServer™.** cost as a typical calibration. **An optional Porous Stainless Steel Cap iP-SC is available for industrial probes. iP-SC Standard** **1** **or Shop Online at** _**omega.com[SM]**_ **To Order, Call** OMEGA offers replacement probes with optional 3-point NIST traceable calibration certificates. ## **Typical Applications** The OMEGA iTHX is great for monitoring temperature and humidity in applications such as: clean rooms, computer rooms, HVAC systems, pharmaceutical and food processing and storage, hospitals, laboratories, semiconductor labs, electronic assembly, warehousing, museums, manufacturing, greenhouses and, farm animal shelters. ## **Sensor Specifications RELATIVE HUMIDITY (RH)** **Accuracy/Range at 25°C - Non-Condensing:** **10 to 90%:** ±2.75% **5 to 10% and 90 to 95%:** ±3% **0 to 5% and 95 to 100%:** ±4% **Non-Linearity:** ±3% **Hysteresis:** ±1% RH **Response Time:** 8 seconds, tau 63% **Repeatability:** ±0.1% **Resolution:** 0.1%, 12 bit ## **TEMPERATURE** ## **Accuracy/Range**** : **Wand Probe:** ±0.5°C (±1°F) for 5 to 45°C (41 to 113°F); up to ±1°C (up to ±2°F) for 0 to 5°C and 45 to 70°C (32 to 41°F and 113 to 158°F) **Industrial Probe** : (see chart in manual) ±0.5°C (±1°F) for 5 to 45°C (41 to 113°F); up to ±1.5°C (up to ±2.7°F) for -40 to 5°C and 45 to 124°C (-40 to 41°F and 113 to 255°F) _**** Note:** Extended temperature range is for industrial probe only, refer to the iServer’s operating temperature spec._ **Response Time:** 5 to 30 seconds, tau 63% **Repeatability:** ±0.1°C **Resolution:** 0.1°C, 14 bit ## **Probe Specifications** **iTHP-W:** 198 x 19 mm Dia ( 7.8 x 0.75") **Cable** : 152 mm L (6") with DB9 conn. **Cable Operating Temperature:** 0 to 80°C (32 to 176°F) **iTHP-5, iTHP-2** : 137 or 51 L x 16 mm Dia (5 or 2 x 0.63") - **Housing Material:** 316 SS **Cable** : 3 or 0.9 m L (10 or 3') **Cable Operating Temperature:** - -40 to 125°C (-40 to 257°F) **NIST-Traceable Calibration Certificate available.
