Wireless Temperature Monitoring

Our D3 Wireless Temperature Monitoring system automatically monitors temperature, humidity and other factors and will alert you when anything is out of range.

This affordable wireless temperature monitoring system is a durable and reliable technology. Helping you stay HACCP, BRC & MHRA compliant. The D3's versatility and range of functions makes it suitable for many applications.

Made in the UK. Exclusively available in Northern Ireland from Tendo Systems.

At a glance...

Sensors with long-range radio frequency transmitters are placed throughout your facility. Every 60 seconds a measurement is transmitted to the touch-screen base unit receiver. The base unit records and analyses every reading. If a measurement is outside your pre-set parameters, for a predetermined length of time, email / SMS alerts are sent.

    • Wall mounted touch-screen base unit

    • Alarms via email / SMS

    • Audit-ready reports produced

    • No more manual temperature records

    • Assists compliance with industry standards

    • No WiFi required

    • No software installation required

    • No on-going payments

    • Annual calibration service available

Wireless Sensor / Transmitter

The long-range D3 wireless transmitters are robust and can stand the test of time. With probes and attachments for virtually all applications, they can be configured to meet and exceed your needs. If the 250 metre range is not enough, inexpensive repeaters can be added to make sure you have complete coverage in your facility.

    • 250 metre range

    • 5 year battery, easily replaced

    • Transmits reading every 60 seconds

    • Temperature range: -200 to +200°C

    • Water resistant to IP68

Not just temperature...

Our D3 system can monitor more than temperature. Our vast range of sensors can monitor Relative Humidity | Energy Kwh | Door Sensors | Pulse Sensors | Concentration (ppm) | Digital Input | Linear (4-20mA / 0-10v). If it needs monitored, we can take care of it. Up to 150 sensors can be added to one system. If you need sensors added at a later date, it's no problem.

Email / SMS Alerts

When something goes wrong, you need to know about it. Our D3 system can be easily configured to send email and/or sms alert messages when measurements go outside of your pre-set limits. You will also be informed if a sensor goes offline or if the battery is running low. There are no hidden costs for this - our D3 system is fully functional from day one.

Wireless Monitoring FAQ

How are the wireless temperature sensors powered?

Our wireless temperature sensors / transmitters are powered by an AA size Lithium battery. The batteries will last up to 5 years and they are easily replaced.

As a transmitter’s battery level reduces, you will see visual indication on your computer / smartphone screen.  When the level drops to a critical level, you will receive an email alert.

If you require annual calibration / maintenance services, we will check the level of charge in your batteries and replace them as part of the service.

How much does a wireless temperature monitoring system cost?

There are many variables. The answer depends on the quantity and type of sensors you need. It also depends on the size of your facility and if Repeaters (signal boosters) are required.

We can talk you through this via phone or email. Or, you can complete this Estimate Request form and we’ll get back to you ASAP.

What is the maximum range of a temperature sensor/transmitter?

Our wireless sensors can transmit up to 1km outdoors, with no obstacles. When inside buildings, the range can be around 300 metres. Ultimately, the range of a temperature sensor depends on walls and other obstacles in the building.

We can install Repeater units to increase the signal range. These Repeaters can be daisy-chained and so the transmission range of a wireless sensor can be increased as required.
