The Swift Sensors SS3-105S pairs a food-grade stainless steel probe with a 1 m (3 ft) lead for durable, hygienic temperature monitoring in coolers, freezers, and liquids. The rugged probe stands up to washdowns and demanding cold-storage environments.
Typical applications
- Walk-in coolers and freezers
- Vaccine and lab refrigerator monitoring
- Food-service and commercial kitchens
- Liquid and immersion temperature
- Cold-chain storage and transport

How the Swift Sensors wireless system works
This sensor pairs with a Swift Sensors Gateway (sold separately), which securely transmits encrypted readings to the Swift Sensors Cloud over Wi-Fi, Ethernet, Power-over-Ethernet, or cellular using 256-bit AES encryption. View live and historical data from any computer, tablet, or smartphone in the Swift Sensors Console, and set custom thresholds that trigger instant SMS text, email, and phone-call alerts.
- Plug-and-play deployment — no wires to run and no software to install; sensors auto-pair with the gateway in minutes.
- 6–8 year battery life from two replaceable AAA lithium-polymer batteries.
- BLE5 wireless range up to 250–300 ft line-of-sight; each gateway supports up to 150 Series 3 sensors.
- Secure, scalable cloud architecture — from a single sensor to thousands across multiple sites.
- Two-year warranty and satisfaction guarantee. NIST-traceable calibration certificates available on temperature and humidity models.
Completing the system
- Gateway — the SS3-105S reports through a Swift Sensors SG3-1010 gateway; one gateway supports up to 150 sensors within a 500 ft radius, in any mix of types.
- Cloud Monitoring plan — priced by the number of sensors deployed, paid monthly, annually or multi-year, with no contract required. Email support@labsupplies.com with your sensor count for plan pricing.
