A professional, pen-style waterproof data logger delivering highly accurate temperature and humidity readings with instant plug-and-play PDF reporting.
The Elitech RC-51H is engineered to take the stress out of compliance auditing. Designed specifically for medical cabinets, fresh food storage, and laboratories, this pen-style data logger seamlessly records both temperature and humidity. With a massive 32,000-point memory capacity, it provides uninterrupted monitoring for months at a time, ensuring your critical stock remains within safe parameters.
Say goodbye to clunky software and expensive subscriptions. The true power of the RC-51H lies in its plug-and-play USB design. Simply remove the waterproof cap, plug the logger directly into any PC or Mac, and it will instantly generate a comprehensive PDF report. This streamlined process makes handing over data during MHRA or food safety audits incredibly straightforward.
Boasting an IP67 waterproof rating, the RC-51H thrives in demanding environments. The clear, multi-function LCD screen provides instant visual confirmation of current readings, alarm statuses, and battery life without needing to interrupt the logging process. Combined with a factory calibration certificate, this is the ultimate budget-conscious solution for uncompromising professional monitoring.

We use these in our community pharmacy's vaccine fridges. The fact that I can just plug it into the computer and instantly print a PDF report for our MHRA audits is a lifesaver. No software fuss at all.
Sarah Mitchell, London

Perfect for our commercial food storage. The IP67 waterproof rating means we don't have to worry about condensation in the walk-in chillers damaging the units. Highly accurate and reliable.
James Henderson, Manchester

As a laboratory manager, having the factory calibration certificate included in the box saved us a lot of time and money. The dual temperature and humidity tracking is excellent for our incubator monitoring.
Dr. Emily Clarke, Edinburgh

Great little logger. The auto PDF feature is brilliant. I'm dropping one star because the Mac version of the configuration software is a bit clunky to install, but once set up, the device itself is flawless.
Oliver Wright, Bristol

We replaced an incredibly expensive, temperamental Wi-Fi system with a 5-pack of these Elitech loggers. The total cost of ownership is so much lower, and manual USB downloads actually force our staff to physically check the fridges.
Rebecca Thompson, Leeds

Very robust and accurate. The clear cap over the USB can be quite stiff to remove the first few times, but I suppose that's necessary to maintain the waterproof seal. Good value for money overall.
David Patel, Birmingham
