What Signatrol does

Signatrol is a privately-held UK manufacturer specializing in temperature, humidity, and environmental data loggers and data logging systems, founded in 1994 and headquartered in Tewkesbury, Gloucestershire. The company designs and manufactures both hardware and proprietary software in-house at its UK development centre, producing miniature button loggers (SL50 and SL60/dLog series), single-use and multi-use USB loggers (tempmate family), patented wireless monitoring systems (Spydaq), Wi-Fi enabled devices (Cadmus), and real-time GSM/LTE trackers (tempmate-GM2). It also offers UKAS ISO 17025-traceable calibration services and complementary software platforms including TempIT, Tempbase 2, and the cloud-based Ratifi monitoring platform.

The company serves regulated and quality-sensitive industries including food and beverage, pharmaceuticals, medical and healthcare, cold chain and logistics, agriculture, and facilities management, where it positions itself on precision (accuracy up to ±0.1°C), comprehensive regulatory compliance (FDA 21 CFR Part 11, EN 12830, HACCP, BRC, SALSA, ISO 9001:2015), and product durability (IP68 waterproofing validated through 23 months of water immersion testing). Its go-to-market combines direct UK e-commerce with same-day despatch, phone-based enterprise sales, and a 15+ country international distributor network spanning Europe, the Middle East, Asia Pacific, and North America.

Revenue is generated primarily through one-time hardware sales (ranging from budget £11 single-use devices to £1,456+ starter kits and premium accessories), perpetual software licenses (TempIT5-PRO at £170 per seat), and recurring calibration services (£60–80 per unit with 5-day turnaround). The company is founder/management-owned with no disclosed external funding, operates with 1–10 employees, and serves named customers including the NHS alongside unnamed top food and pharmaceutical brands globally.
