Every Saga
Every model features:
E Ink display, status LEDs
Alarm state, current, minimum, and maximum temperature readable on the unit itself.
Rechargeable, and not dangerous goods
A rechargeable NiMH battery, not classed as dangerous goods, rated for at least 70 charge cycles. The same USB-A cable charges the device and downloads its data.
Automatic flight mode
Approved by over 200 airlines. IATA, FAA, and EASA compliant.
Global 4G, 3G, and 2G
Location with every report, by cellular triangulation and 2.4 GHz Wi-Fi detection. Geofences from 250 m to 15 km.
150 days of memory
21,600 readings at 10-minute intervals logged on the device, and reported once it is back in coverage.
Excursion wake-up and light sensor
Reports the moment temperature leaves its range, regardless of schedule. A change in temperature or light triggers an alert.
CE, FCC, IC, NOM, KC
Calibration certificate for every device, in the platform.
Probe and accessories
What ships with the device
PR-T80 digital probe
One probe for dry ice and liquid nitrogen
Saga Dry Ice and Saga Cryogenic use the same PR-T80 probe. Only the calibration differs: −80, −40, and 0 °C for Dry Ice, with −196 °C added for Cryogenic. Each device ships with its probe, calibrated for that model.

Questions about Saga devices
Is a Saga device a data logger?
It does what a temperature data logger does, and more. Like a data logger, it records the temperature at a set interval. Unlike a data logger that is read out after arrival, it reports its readings and its location over the cellular network while the shipment moves, so an excursion can be acted on in transit. It is reusable: Controlant runs the returns, recalibration, and charging as a managed service.
What network do Saga devices use?
Saga devices report over the cellular network, on 4G, 3G, and 2G, roaming globally. Location is resolved with every report from cellular triangulation and 2.4 GHz Wi-Fi detection, so it does not depend on a satellite fix. Saga Card, smaller than a credit card and piloting from Q1 2027, uses LTE-M and NB-IoT. There is no gateway, reader, or short-range network to install at either end of a lane.
Are Saga devices reusable?
Yes. Saga is a reusable device on a rechargeable cell, not a single-use logger. Controlant runs the return logistics, recalibration, and charging as a managed service, and a device dashboard shows what is in circulation, its health status, its recalibration due date, and its usage.
What temperature ranges do Saga devices cover?
The family covers −200 to +50 °C. Saga-P Standard covers −20 to +50 °C, Saga Arctic covers −30 to +30 °C, Saga Dry Ice reads to −95 °C through the PR-T80 probe, and Saga Cryogenic reads to −200 °C through the same probe. For each model's calibration points and accuracy, see its datasheet and the comparison above.
How long does a Saga device run between charges?
On the 2500 mAh cell shared by three of the four models, 20 days at a 1-hour wake interval and over 110 days at 24 hours. Saga Arctic uses a 1200 mAh cell and runs 10 days at a 1-hour interval and over 55 days at 24 hours. The device's NiMH cell is not classed as dangerous goods and recharges over the attached USB-A cable.
Are Saga devices approved for air freight?
Saga devices are approved by more than 200 airlines, and are IATA, FAA, and EASA compliant.
