Product information

  • Measuring task Temperature

Pt100 network thermometer and data logger with alert feature

Querx PT100 supports a wide range of Pt100 temperature sensors and can therefore be utilized in a variety of application areas.
The device measures temperatures, tracks the data and provides it via Ethernet and cloud services. An interactive graph visualizes the data and alerts can be triggered when critical values are reached.
The smart sensor can be easily integrated into existing networks. It is configured and controlled via the graphical web interface - no additional software is required.


Precise temperature measurements with external Pt100 sensors

  • Querx PT100 supports 2-, 3- and 4-wire Pt100 sensors. Depending on the sensor that is used, temperatures between -328 °F and 1382 °F (-200 °C and +750 °C) can be measured.
  • A vast number of cable-, contact- and outdoor-sensors, which are all suited to different applications are available from various manufacturers.

Uninterrupted data tracking

  • The minimal, maximal and average temperature measurements are saved on the device for at least 51 days (1 entry / minute) up to 8.4 years (1 entry / hour).
  • The data is also safely stored if a power shortage should occur.

Alerts and notifications

  • Querx PT100 sends automatic emails, SNMP-traps and syslog messages if
    • the temperature is too high or low,
    • the temperature is rising or falling too quickly
    • and once the temperature has returned to its normal range..
  • Emails are encrypted (TLS/StartTLS). Up to 4 recipients can be notified and 2 configurable mail-servers ensure that alerts are sent even if one of the servers should fail.

User-friendly web interface

  • The device’s interactive HTML5 web interface facilitates real-time access to all data, as well as its visualization on your PC, tablet or smartphone.
  • Measurements can be exported in the XML- or CSV-formats and can thus be used in Excel or other applications, for instance.
  • The interface is available in English or German.

Various interfaces for data access

  • Querx sensors can be integrated into network monitoring systems such as Zabbix or Icinga via SNMP.
  • Modbus/TCP makes it possible to apply the device in industrial process monitoring (SCADA) and other automation systems.
  • All current and saved measurements can be queried in the formats XML, CSV and JSON via HTTP.

Supports cloud services

  • Querx supports the cloud services ThingSpeak, Xively and dweet.io. You can access your data via your web browser or an app wherever you are.
  • The data can be integrated into your own applications from the cloud via the programming interfaces (APIs) offered by the provider you have chosen.

Easy to set up and configure

  • Each Querx sensor is automatically allocated an IP address via DHCP during setup. The application Device Discoverer helps you keep track of all the Querx sensors on your network.
  • Since Querx supports mDNS/Bonjour, the devices can also be reached on your local area network via a fixed system name specified by you.
  • The device is configured via an intuitive web interface.


  • Querx PT100 works reliably within the temperature range of -40 °F to 185 °F (-40 °C to 85 °C).
  • Due to its compact case of 2.2 x 1.6 x 0.8 in (56.3 x 40 x 21 mm),, Querx can be installed even in tight places.
  • Status LEDs visualize alarm states, network link and network activity..
  • An integrated, battery backed real-time clock keeps the time up to date even in the case of a power shortage or an inaccessible SNTP server.
  • Power is supplied via a micro USB input, either from a free USB port or an external EU power supply. The power consumption is less than 1 watt.
