- ±1.4 °C
- at −200 to −90 °C
- Housing
- 61 × 98 mm
- 25 mm deep, 194 g
- IP rating

Key capabilities
−200 °C operation
The PR-T80 probe, calibrated at −196, −80, −40 and 0 °C, monitors liquid-nitrogen shipments in real time.
Cell and gene therapy ready
Location, temperature, and light tracking for the most valuable therapies.
Validated for the life sciences supply chain
Validated monitoring with a complete audit trail, on the same platform as the rest of the lane.
Specifications
Built for liquid nitrogen down to −200 °C
Full specifications from the Saga Cryogenic datasheet, version 2, 7 April 2026.
Limited range
The probe reads to −200 °C. The device itself rides outside the liquid nitrogen at −20 to +50 °C; between −30 and −20 °C it still logs, with reduced battery life, but stops reporting in real time.

Battery life
Set the wake-up interval, read the days
A fully charged device on the interval shown reports in real time and raises alarms for at least this long while monitoring a shipment inside its operating range. Below 5% charge it hibernates: it keeps logging to memory and stops reporting until recharged.
| Wake-up interval | 2500 mAh |
|---|---|
| 1 hour | 20 days |
| 2 hours | 35 days |
| 3 hours | 45 days |
| 6 hours | 75 days |
| 12 hours | 110 days |
| 24 hours | over 110 days |
In the cold
For the most extreme cold chains
Cell and gene therapies travel in liquid nitrogen, where most monitoring is read only after arrival. Saga Cryogenic reports in real time from the shipper: the reusable device tracks temperature, location, and light exposure, every reading lands in the validated Controlant Platform with a complete audit trail, and the cryogenic probe has an operating range from −200 °C to +50 °C.
That range covers cryogenic transport and cryogenic storage, so traceability, regulatory compliance, and product safety hold across both rather than stopping at the loading dock.
Device management is handled
Return logistics, calibration, and servicing are ours to run, which keeps a device and its probe in circulation rather than in a drawer.
Questions about Saga Cryogenic
How cold can Saga Cryogenic measure?
The PR-T80 probe reads to −200 °C. It is calibrated at −196, −80, −40 and 0 °C on the probe, and accurate to ±1.4 °C from −200 to −90 °C and ±1 °C from −90 to 0 °C.
Where does the device sit in a liquid nitrogen shipper?
Outside it, in its own −20 to +50 °C band, with only the probe in the cold. Between −30 and −20 °C the device still logs, with reduced battery life, but stops reporting in real time.
Is it the same device as Saga Dry Ice?
Same Saga-P housing and the same PR-T80 probe. What differs is the calibration and the accuracy bands: Cryogenic is calibrated at −196, −80, −40 and 0 °C on the probe and reads to −200 °C; Dry Ice stops at a −80 °C point and reads to −95 °C.
