Always ask for a long-range signal strength test.

We can prove ours to be unrivalled.

Wireless temperature monitoring technology you can trust

The term remote temperature system often refers to the wireless capability of system and this is where we excel. However the use of data radio communication at low powers within or between buildings is a problematic area, with many pitfalls for the unwary Designer and User.

The Hanwell IceSpy wireless temperature monitoring systems embody 25 years of engineering expertise in this area to ensure the best possible performance with a reliability that is guaranteed. This, coupled with an unrivalled ability to plan and commission robust systems, means that you can trust what we say. This is evidenced by many thousands of systems using our remote temperature validation systems worldwide today, with many still operating after 25 years.

Unfortunately, wild claims are easy to make but they do not substitute for real expertise. We are more than happy to prove our claims to you at any time before purchase, just please make sure that you ask the same of all potential vendors.

Validation of wireless temperature monitoring

We offer validation documentation for our Hanwell IceSpy system which includes Installation Qualification (IQ) and Operational Qualification (OQ) protocols for hardware and software validation. This is typically required in Healthcare and Laboratory environments and we have vast experience in this area. Contact us today to talk more about this area of our business.


Convenient, reliable on-site calibration is available for minimal disruption. Alternatively, our in-house calibration using our calibration lab technicians provides our customers with flexibility in cost and convenience for ongoing maintenance of your investment with a multitude of calibration points and UKAS certification where required.
