The data logger for temperature and humidity also calculates the dew point, absolute humidity and the water vapor content in the air. The data logger for temperature and humidity is used for stationary monitoring of laboratories, greenhouses, medicine and food stores, museums, etc. The data measured and calculated by the data logger for temperature and humidity are stored in the internal memory and can be called up via Ethernet and sent to the user. In addition to storing the measurement data, the data logger for temperature and humidity can send alarms by email or display them on a website. The data logger for temperature and humidity can be supplied via a power supply unit or autonomously via Power over Ethernet. An internal battery is built into the data logger for temperature and humidity to buffer the memory and the settings.<\/p>\n<p>In addition to the built-in Ethernet interface, the data logger for temperature and humidity also has an RS485 interface available to the user. This can be addressed via Modbus RTU. The user can communicate with the data logger for temperature and humidity via Modbus TCP \/ IP, HTTP, FTP via the Ethernet interface. A web and FTP server as well as a DHCP and SMTP client complete the functionality of the data logger&#8217;s network interface.<\/p>\n<h3>Highlights<\/h3>\n<ul>\n<li>Temperature measuring range (-20 &#8230; +60 \u00b0C)<\/li>\n<li>Relative humidity measuring range (0 &#8230; 95%)<\/li>\n<li>CO2, TVOC and light measurement<\/li>\n<li>Ethernet interface (PoE compatible)<\/li>\n<li>Alarm (acoustic, email, visual)<\/li>\n<li>4 GB memory<\/li>\n<li>Adjustable sampling \/ storage rate<\/li>\n<li>FTP, HTTP server<\/li>\n<\/ul>\n<h3>Technical specifications<\/h3>\n<ul>\n<li>Measured variableAir humidity \u2014 Measuring range: 0 &#8230; 95% r.H.<\/li>\n<li>Measured variableAir humidity \u2014 Accuracy: \u00b1 3 % of reading (10 .. 90 %)<\/li>\n<li>Measured variableAir humidity: \u00b1 5 % of other<\/li>\n<li>Measured variableAir humidity \u2014 Resolution: &#8211;<\/li>\n<li>Measured variableTemperature \u2014 Measuring range: -20 &#8230; 60 \u00b0C<\/li>\n<li>Measured variableTemperature \u2014 Accuracy: \u00b1 0.6 \u00b0C (10 &#8230; 40 \u00b0C)<\/li>\n<li>Measured variableTemperature: \u00b1 1 \u00b0C of other<\/li>\n<li>Measured variableTemperature \u2014 Resolution: &#8211;<\/li>\n<li>Measured variableIlluminance \u2014 Measuring range: 0 &#8230; 60000 lx<\/li>\n<li>Measured variableIlluminance \u2014 Accuracy: &#8211;<\/li>\n<li>Measured variableIlluminance \u2014 Resolution: &#8211;<\/li>\n<li>Measured variableTVOC \u2014 Measuring range: 0 &#8230; 60000 ppb<\/li>\n<li>Measured variableTVOC \u2014 Accuracy: &#8211;<\/li>\n<li>Measured variableTVOC \u2014 Resolution: 1 ppb (0 &#8230; 2008 ppb)<\/li>\n<li>Measured variableTVOC: 6 ppb (&#8230; 11110 ppb)<\/li>\n<li>Measured variableTVOC: 32 ppb (&#8230; 60000 ppb)<\/li>\n<li>Measured variableCO2 \u2014 Measuring range: 400&#8230; 60000 ppm<\/li>\n<li>Measured variableCO2 \u2014 Accuracy: &#8211;<\/li>\n<li>Measured variableCO2 \u2014 Resolution: 1 ppm (400 ..1479ppm)<\/li>\n<li>Measured variableCO2: 3 ppm (&#8230; 5144 ppm)<\/li>\n<li>Measured variableCO2: 9 ( &#8230;17597 ppm)<\/li>\n<li>Measured variableCO2: 31 ppm ( .. 60000 ppm)<\/li>\n<li>saturated steam pressure, enthalpy \u2014 Interface: RS485 (Modbus RTU)<\/li>\n<li>Ethernet Modbus TCP, HTTP, FTP, MQTT: Memory 4 GB<\/li>\n<li>Ethernet Modbus TCP, HTTP, FTP, MQTT \u2014 Power supply: DC power pack 6 V \/ 1 A<\/li>\n<li>Ethernet Modbus TCP, HTTP, FTP, MQTT: PoE IEEE 802.3af<\/li>\n<li>Ethernet Modbus TCP, HTTP, FTP, MQTT \u2014 Power consumption: &lt; 2 VA<\/li>\n<li>Ethernet Modbus TCP, HTTP, FTP, MQTT: Warm-up time 15 minutes<\/li>\n<li>Ethernet Modbus TCP, HTTP, FTP, MQTT \u2014 Operating conditions: -20 &#8230; 60\u00b0\/ 95% r.H<\/li>\n<li>Ethernet Modbus TCP, HTTP, FTP, MQTT: Degree of protection IP20<\/li>\n<li>Wall mounting, sensor facing down \u2014 Dimensions: 120 x 80 x 25 mm<\/li>\n<li>Wall mounting, sensor facing down \u2014 Weight: 300 g<\/li>\n<\/ul>\n<h3>Delivery scope<\/h3>\n<ul>\n<li>1 x Data Logger for Temperature and Humidity PCE-HT 422<\/li>\n<li>1 x instruction manual Note: The power supply unit must be selected as an option!<\/li>\n<\/ul>\n<h3>Documents<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.pce-instruments.com\/eu\/api\/getartfile?_fnr=1765173&amp;_dsp=inline\">Supplier document<\/a><\/li>\n<li><a href=\"https:\/\/www.pce-instruments.com\/eu\/api\/getartfile?_fnr=1765174&amp;_dsp=inline\">Supplier document<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Data logger for temperature, relative humidity, CO2, TVOC and light intensity \/ 4GB memory \/ Power over Ethernet \/ MQTT \/ Email alarm \/ HTTP \/ FTP.
