Richard Paul Russell Limited

Wireless Connected (50 Series) Data Loggers

These SpaceLoggers are either connected by Wi-Fi, which are the 50 series SpaceLoggers, or by Bluetooth for the DROP loggers.

The 50 series of compact low energy consumption data loggers have been designed by our engineers for industry specific applications. If you have an OEM requirement then please see our OEM page and call us to discuss.

The DROP loggers are small, rugged, waterproof, and accurate environmental data loggers with integral sensors. Kestrel LiNK is the free app the powers the DROP data logger. With Kestrel LiNK on your smart phone or tablet, you can view real-time readings from any DROP logger within wireless range (up to 30m or more line of sight) via Bluetooth low energy.

Richard Paul Russell has supplied SpaceLoggers to be utilised in a wide range of applications. Please read our case studies for the 50 series data loggers.
