Air Humudity Meter PCE-HT 420
Data logger for temperature and humidity / MQTT / Power supply unit or PoE (Power over Ethernet) / LC display / Visualization in web browser / 8 GB memory
The air humidity meter is used to monitor the temperature and humidity. The air humidity meter is equipped with a network interface. This makes the air humidity meter an ideal solution for objects in which the measurement data must be continuously recorded and monitored. The air humidity meter continuously stores the measured values on its internal memory. This is read out via browser or FTP client. The web browser also makes all the settings on the air humidity meter. No additional software is needed. The architecture of the air humidity meter allows up to 10 users to dial in to the air humidity meter at the same time. Different access levels prevent unauthorized users from making settings to the air humidity meter.
In addition to storing the measured values, the air humidity meter can also alert the user to an alarm when the limit value is exceeded. Furthermore, various users can be notified of this alarm via email.
The air humidity meter measures and calculates the following climatic variables:
- Relative humidity
- Dew point
- Absolute humidity, ie amount of water vapor (in grams) per m³ of atmosphere at certain
- Cooling limit temperature
- Saturated vapor pressure, ie pressure, at which gas at the specified temperature in equilibrium with liquid
(equilibrium between evaporation and condensation)
- Enthalpy (energy content)
The air humidity meter is supplied via an external power supply unit or via Power over Ethernet. The built-in FTP server provides quick and easy access to archive files using an Internet browser or from the interface of another FTP client. The DHCP protocol allows you to automatically configure the air humidity meter on the computer network. Furthermore, the data logger supports the Modbus TCP / IP protocol, so that the air humidity meter can also be integrated in machines. All these features make the air humidity meter an important instrument wherever indoor climate needs to be monitored.
