FAQ

What is the difference between single-use and reusable data loggers?

Single-use loggers (ULogs series) are pre-calibrated and ready to use out of the box; after one shipment they are discarded or recycled, which makes them ideal for one-way exports and shared logistics. Reusable loggers (BLog and WLogmp series) can be stopped, restarted and re-deployed for many trips, lowering the cost per shipment for companies with high shipping volume. The right choice depends on whether you control the return of the device after delivery.

What temperature data loggers does SigmaWit manufacture?

SigmaWit manufactures five main product families: single-use USB temperature loggers (ULogs series), reusable Bluetooth data loggers (BLog series), real-time 4G tracking loggers (GLogs series), WiFi data loggers with external probes (WLogmp series), and BLE thermo-hygrometers (T201 / T281). All products are designed and manufactured in our own factory in Shenzhen, China, for cold chain monitoring in food, pharmaceutical and industrial applications.
