Reliable for Cold Chain
We use these in our delivery trucks to monitor frozen goods. The signal strength is consistent and the battery life is impressive.

Long Battery Life
Installed 6 months ago and still showing full battery. Perfect for hard-to-reach cold storage units.

Signal Strength Varies
Works fine in open areas but struggles to penetrate thick insulated walls in our facility. Might need a repeater.

Accurate Readings
Compared this against our calibrated lab logger and the readings were nearly identical. Great value for the price.

Good Sensor, Easy Setup
Works well for our warehouse storage. Setup was straightforward. Only downside is the gateway hub is sold separately.
Q: What is the wireless range?
A: In open space, the range is approximately 100 meters. Walls and metal structures may reduce this distance.
Q: Does it alert on high temperature?
A: The probe logs the data. Alerts are configured through the gateway software when thresholds are breached.
Q: Is the device pre-calibrated?
A: Yes, each unit is factory calibrated. We recommend an annual verification check for critical environments.
Q: Can I replace the battery myself?
A: Yes, the battery compartment is user-accessible and uses a standard 3.6V lithium battery.
Q: Does this connect directly to WiFi?
A: No, this probe uses RF transmission to connect to a gateway hub, which then connects to your network.
