New !

Ethernet thermometer is designed for ambient temperature measurement and measurement from up to four external temperature cable probes. Measurement in degrees Celsius and degrees Fahrenheit supported. Ethernet thermometer is built in a durable plastic case.

APPLICATIONS - measuring and control of temperature at:

• server rooms
• telecommunication devices
• warehouses
• glasshouses
• manufacturers
• museums, archives, galleries
• air-conditioned rooms

Thermometer is equipped with no display. Ethernet interface enables to control thermometer via PC. The following communication modes are supported:

MODES OF COMMUNICATION
Modbus TCP:	Modbus TCP protocol enables to read measured values, set alarm limits, adjust the probe.
Telnet:	Port 9999 enables to set alarm limits (lower, upper limits, hysteresis for temperature and time delay), e-mail addresses, SNMP addresses, probe description, refresh of www pages (10s to 65535s), set storing interval to history (10s to 65535s), enable each communication channel. Capacity of the history memory is 100 values. Password protection of this port is enabled. Automatic IP address assignment from DHCP server is also enabled.
WWW pages:	User selectable design of www pages enabling to display curve of measurement history. User can design the look of www pages and temperature history.
SNMP:	It is possible to read actual values and alarm limits. In case of alarm creation warning message (trap) is sent to addresses defined by the user (maximum three addresses).
SOAP:	Transmitter enables to send actual measured data in the format of SOAP message to selected web server in preset interval 10-65535 s. In case message is not received by the server till next message is sent, warning trap 1/2 is sent.

Thermometer enables to monitor measured values. In case of exceeding of adjusted limits warning message can be sent to specified addresses.
There are the following options of alarm indication:

ALARM INDICATION OPTIONS
E-mail:	In case of alarm creation warning e-mail message is sent to addresses defined by the user (maximum three addresses).
SNMP:	In case of exceeding of adjusted temperature limits alarm is activated and warning trap is sent to user specified IP addresses (maximum 3 addresses).
WWW pages:	In case of exceeding of adjusted temperature limits active alarm is displayed on www page.
syslog:	Transmitter enables to send text messages to selected syslog server after different events appear. E.g. after transmitter restart, alarm activation, communication error with SNTP, write to transmitter via mdb, sntp, after firmware change, after alarm termination, after communication error with SOAP server.

Synchronizing of time and record to www table and temperature history is enabled by SNTP via Internet.

Basic Manual

Appendixes for Manual

Included accessory:

Traceable calibration certificate from the manufacturer, instruction manual. Calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Example of calibration certificate.

Free program TSensor for configuring of the transmitter is ready to download.
Free program SensorReader for logging values from one thermometer to a PC disk file is ready to download. Recorded values in CSV format are easy to process in e.g. Excel.
For acquiring values from several transmitters, third party software is necessary to use. Tested functionality is with programs TIRS.NET, ControlWeb, EasyView. For record of values to graphs via web interface, project Cacti www.cacti.net is available.
