The data logger PCE-HT 420 is used to monitor the temperature and humidity. It has a built-in network interface making it appropriate solution for objects in which the measurement data must be continuously recorded and monitored.
The datalogger continuously stores the measured values on its internal memory. This is read out via browser or FTP client or using the FTP client. No additional software is needed. The architecture of the data logger allows up to 10 users to dial in to the datalogger at the same time. Different access levels prevent unauthorized users from making settings to the datalogger.
The data logger PCE-HT 420 measures and calculates the following climatic variables:
- Temperature
- Relative humidity
- Dew point
- Absolute humidity, ie amount of water vapor (in grams) per m of atmosphere at certain temperature
- 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 data logger 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 datalogger on the computer network. Furthermore, the data logger supports the Modbus TCP / IP protocol, so that the PCE-HT 420 can also be integrated in machines
