Cold Chain Temperature Data Loggers and Wireless Sensors — TZONE & Elitech
SNTech supplies TZONE and Elitech cold chain solutions for food logistics, pharmaceuticals, cold-storage warehouses, and restaurant monitoring. All solutions offer wireless LoRa/4G/WiFi connectivity with cloud dashboards and regulatory-ready reports (HACCP, GDP, SFDA).
Which logger or sensor fits?
Start with one question: do you need to know about a temperature breach afterwards, or while there is still time to act?
- Elitech RC-5 — the simplest, lowest-cost option. A plug-and-play USB logger for basic transport and cold chain checks; you download the data after the trip.
- TZONE TZ-WF502B — real-time over WiFi. Live upload with a built-in LCD and buzzer, storage for up to 20,000 readings, IP65 waterproofing and flight-mode support.
- TZONE TZ-TempU06 — ultra-low temperatures. An external probe for freezer and cryogenic storage, with USB and Bluetooth reporting and automatic PDF/CSV reports for pharma and biotech.
- Elitech RCW3200 + RCW3000 — many points, one gateway. Wireless temperature and humidity sensors report over long-range LoRa to a gateway that uploads by 4G, WiFi or Ethernet, with web and mobile app access.
For refrigerated trucks, SNTech's TMP-01 sensor takes up to four probes over 4G or NB-IoT. For one-off shipments, SNTech also rents data loggers. How cold chain monitoring works, and HACCP, GDP and SFDA explained.

Frequently Asked Questions
How many readings does the TZONE WiFi logger store?
The TZ-WF502B stores up to 20,000 readings, uploads in real time over WiFi, and has a built-in LCD and buzzer. It is IP65 waterproof and supports flight mode for air shipments.
Which logger handles cryogenic or ultra-low-temperature storage?
The TZONE TZ-TempU06 is built for ultra-low-temperature environments, using an external probe for freezer and cryogenic storage, with USB and Bluetooth reporting and automatic PDF/CSV reports.
How does the Elitech wireless system connect?
RCW3200 sensors communicate over long-range LoRa to the RCW3000 gateway, which uploads data to the cloud by 4G, WiFi or Ethernet. Readings and alerts are then available on the web and in the mobile app.
What is the lowest-cost way to monitor a shipment?
The Elitech RC-5 USB logger is a compact, plug-and-play option for basic cold chain or transport monitoring. For a single shipment, SNTech can also rent a logger instead of you buying one.
Which logger should I use in a refrigerated truck?
For live monitoring on the road, SNTech's TMP-01 sensor takes up to four probes per unit and uploads over 4G or NB-IoT; if the truck already has a Teltonika tracker, 1-Wire temperature sensors can connect to it instead.
