Accurate measurement

Accurate and robust range of sensors to cover a broad spectrum of environmental conditions such as temperature, humidity, energy, flow and digital status.  In addition you can add custom sensor types to monitor 3rd party sensors which means that just about any measurable factor can be monitored.


We provide a range of sensors that cover a wide measurement range of -200°C to +200°C, with accuracies down to ±0.1°C. These sensors can be supplied with fully traceable UKAS calibration certificates. Our sensors measure air, liquid, LN2, ovens, product simulation and much more.


Our standard range of humidity sensors are ideal for measuring general humidity in offices, warehouses and temperature controlled storage facilities over the range of 0-100%RH, with accuracies up to ±1.5%RH. Humidity sensors can be supplied with fully traceable UKAS certificates. We can also supply industrial humidity sensors designed for constant high humidity applications.

Energy & Flow

Our pulse count sensor connects directly to a meters pulsed output to provide accurate energy and flow data. This is ideal for monitoring energy and flow data in industrial applications and production environments.

Door Events

Our sensors can provide a count and state of door events. Ideal to notify door open events for chiller and freezer cold stores, walk in fridges, vaccine stores and any other general door monitoring. The door alarm parameters can be configured with a delay to reduce nuisance alarms.

Pressure & Gas

We provide 4-20mA and voltage sensors to interface to a range of pressure and gas sensors for many industries. Typical use is refrigerant pressure in HVAC system, differential pressure in sterile work environments and CO2/O2/N2 sensors to provide accurate and reliable monitoring of gas levels.

ANY Physical Quantity

We have a range of linear input voltage and current sensors for connection to third party equipment. Voltage and current outputs are standard for industrial and environmental sensors. Simply adding a sensor profile provides access to a multitude of sensor types such as temperature, pressure, wind, light or any other physical quantity.

Powerful browser-based user interface

Data Security

Data is stored in a secure tamper-proof format and cannot be amended or changed by any user. All data is automatically backed up to an internal industrial grade micro SD storage card.

To provide continuous monitoring, in the case of power loss, the base station can come with an optional internal 12 hour rechargeable battery backup.

Robust wireless monitoring

Our industrial strength wireless network can work in the most harsh environments routing data around the most complex structures and re-routing and adapting as the surrounding environment changes.

Base Station

The base station connects to the local IT network. It receives data from the wireless sensors and provides secure multi-user access to data records and audit trails from any web browser enabled device.

no subscription system

Wireless Sensors

The wireless transmitter sends this sampled reading securely to the base station every minute. If they are not within distance of the base station they can route the message though any local router.

no subscription system

Wireless Routers

Routers are used to strengthen the network and forward messages from wireless sensors when they are not within radio distance of the base station. Routers are mains powered and can route the message between other routers to adapt to the local environment to find the best path back to the base station.

Market sectors and applications

Tek Troniks monitoring systems are used across a broad range of market sectors including medical, warehousing, distribution and throughout the food and healthcare cold supply chain.

Our real-time wireless temperature and humidity monitoring system provides numerous sensor types for a multitude of Agricultural applications including dairy farms to monitor the temperature of milk, greenhouses for fluctuations in temperature, crop storage to reduce the risk of product waste.

Our wireless temperature monitoring systems are used widely across the food sector. We can monitor refrigerators, freezers and temperature controlled storage areas. Continuous real time monitoring provides temperature records for HACCP plans, helps reduce waste from stock losses and provides alarm notifications to prompt corrective action.

Food production companies need to comply with BRC legislations. Our automated temperature monitoring provides temperature records for external audits while reducing labour and risk of error. We can monitor the ambient temperature and humidity of production areas, temperature controlled storage and ovens. Continuous real time monitoring provides alarm notifications of temperatures throughout the production cycle.

Yes. Our wireless transmitters are long range and are designed to work over large and complex structures. Follow this link for more information of temperature monitoring for warehouses and temperature controlled storage.

Requirements to monitor temperature are going to come from your industry sector, legislative, audit and your customers requirements/demands.

There are requirements in food and medical applications for temperature monitoring - in manual or electronic formats.

We are seeing more & more request for continuous monitoring as audits become more stringent in their demands.

The benefits of continuous temperature monitoring over manual readings are;

Continuous Monitoring Manual Checks
If set points are exceeded alarm notifications are sent. Therefore you know about a problem and have a chance to resolve it before stock is lost. With 2 or 3 readings per day, you won't know you have a problem until a reading is taken. Once aware you're unsure how long you've had the issue for!
Readings are recorded by the system every minute. The readings can be seen live and historical data can be viewed in a graphical format. Hand written staff records are not often captured in any applications where analysis can be completed.
Calibrated sensors and automatic readings give confidence that the reading recorded is the actual temperature at that point in time. Transposed numbers on written records and staff making other simple mistakes when recording data occur frequently.
Data is recorded 24/7/365 and your warned if you have an issue, not matter what's happening in the business. Staff forget to take manual readings and those taken are rushed, who does the reading when the business is closed?
Though there's a cost for our systems there're no on-going fees, calculated over the lifetime of the system the cost per day per sensor are minimal. How much does it costs to take manual records and document there properly, just once or twice per day?

You network the base station by plugging the D3 into a network port (or directly into a router), using an Ethernet cable that is supplied.

You or your IT department, can assign the base station a static IP. If this is beyond your knowledge then don't worry, network mode can be chosen which allows your network to automatically assign the details.

The set-up is documented in the manual, as well as support documentation on our website, our specialist support team are available for more assistance.

Yes, there are couple of options.

  • Operate the the base station as a standalone system - live data can be viewed via its display. However no alarm notifications can be sent via email and a laptop/computer will need to be connected directly to see reports and graphs.
  • Connect using a 3G or 4G router - the router will require a data contract, however using this method allows remote access and to view live/historic data in graphical and report format and get email alarms. There are a number of providers for 3G & 4G routers that offer a solution.

When creating system users you have the capability to restrict their access rights. Users can see and do what you choose them to be able to do.

For the UK and Europe we manufacture wireless monitoring systems that use 433Mhz, the benefit over 2.4Ghz is the radio transmissions can travel further meaning less repeaters are required on large sites.

We do have versions of the system using 2.4Ghz for Europe, for the rest of the world we have 2.4Ghz with different output powers (depending on your legislative directives).

The D3 & D3 Medical versions have a 12 hour battery back-up installed as standard. These system can continue to record data even in a power loss situation.

If repeaters are installed then our optional back-up module will be required for these.

Depending on the system variant you can add up to 150 sensors.

These sensors can be of any type and can be added as and when you need to make changes due to legislative requirements or business needs.

Our systems are designed to grow and offer a single point of contact for continual monitoring needs.
