Manufacturing Test, Measurement and Automation Solutions
Since 2014
Devtank Ltd is a Derby based business specialising in test and measurement, automation, and smart solutions. Since our founding in 2014, Devtank has grown into a team of passionate engineers and developers. We have two core brands, HILTOP and OpenSmartMonitor.
How Devtank Began
Devtank began in 2014 as a consultancy and design house, building bespoke solutions for businesses globally. Founders Joe Burmeister and Tim Telford started the business after caving conversations led to putting their expertise of software and hardware together, building solutions from the garage.
With previous industry expertise and experience, we saw a need for cost-effective, robust, and flexible solutions within manufacturing and development testing.
One of our earliest customers was JMA Wireless, a U.S.-based company seeking a robust and user-friendly test system for their production line. At the time, the team consisted of just Joe and Tim — yet they successfully designed and delivered a tailored solution that met all the requirements.
Drawing on their industry expertise, Joe and Tim recognised a major pain point in production testing: most available solutions came with high licensing costs and required extensive training to operate. Their response was to develop a new system — one that was modular, user-friendly, and open source — eliminating unnecessary barriers and making advanced testing more accessible and cost-effective.
Being open source meant no license fees, no specialised training or software, and full flexibility to make it do what you need. The modular build made it easier to maintain and adjust to changing requirements. The use of open software languages, like Python, enabled users to write their own test scripts with ease.
Another component to our solution, which has stuck with us since the very beginning has been our relationship with Raspberry Pi!

HILTOP - Production Testing
Back in 2014, the two founders and current directors, Joe and Tim, saw a dire need for better production test solutions. Together they developed their first product which became the HILTOP. A powerful industrial test computer that is robust, adaptable, and user-friendly. Today, these are being used in multiple industries, including EV charger manufacturing, Space, Satellite, and PCB manufacturing. Paired with our bespoke test fixtures, we will ensure you have a complete test solution built to your requirements.

OpenSmartMonitor - Plug and Play Smart Monitoring
During our days as a bespoke design and manufacturing business, we were approached to design and innovate a new smart monitoring solution to help reduce energy costs and meet compliance. This led to the creation of the OpensmartMonitor – a comprehensive monitoring system featuring plug-and-play sensors, hosting, and a visual dashboard. While most sensor manufacturers focused on measuring individual parameters, we took a different approach by combining the most critical metrics into a single, compact device.
