• wet-bulbtemperature,

• vapour pressure or the pressure at which, in a given temperature, the gas is at an

• enthlapy(totalheatcontent).

HOW DOES HT22IoT WORK IN CASE THE PRE-SET

PARAMETERS ARE EXCEEDED?

The HT22IoT allows up to two defined warnings. Whenever the pre-set parameters

areexceeded,theHT22IoTwillimmediatelysignalthisvia:

• emails,

• messagesonadedicatedwebsite,

• specialsymbolsonthedisplay,

• audiblealerts.

Therefore,everytimetheHT22IoTisconnectedviaEthernetorRS-485,youwillalways

The HT22IoT is equipped with the Ethernet interface enabling its connection

to the local or global network (either LAN orWAN).Thanks to the user-friendly

and intuitive ‘www’ server, you will always have access to the information

regarding:

• currentmeasurementvalues,

• devicestatus.

The‘www’servercallalsoallowyouto:

• configureit

• readtheserialnumber,manufacturingcode,softwareversionandbootloader

version.

The built-in FTP server allows for fast and easy access to archive data files

from the level of web browser or from other FTP clients. The DHCP protocol

provides automatic configuration of the monitor in the computer network,

whereas the SMTP protocol is responsible for sending the warnings via emails.

The HT22IoT monitor can also work in more extensive systems where

the communication protocol Modbus Slave TCP/IP provides a smooth

and reliable reading of all current measurement data.

ETHERNET INTERFACE AND ITS FUNCTIONALITY

MEASUREMENTS ARCHIVE

Thanks to the dedicated website, you can also check the archive data using

a smartphone, tablet or a PC. There is no need to be worried about insufficient

memory on the device; the HT22IoT has an 8GB internal file system memory

where the data form the internal memory buffer (4GB) is automatically

recorded as files. The memory has a form of a circular buffer and after

the storage is full, the oldest files are overwritten. The internal archive can be

read, copied and/or deleted.
