Frequently Asked Questions
The Tempo Disc Maxi Alert focuses on temperature with maximum storage capacity (100,000 data points) and the highest accuracy (±0.1°C). If you only need temperature monitoring—such as for freezers, refrigerators, or transport—this dedicated sensor provides longer data history and simpler compliance reporting without unnecessary humidity data.
With 100,000 readings—twice the capacity of our multi-sensor models—you can log at shorter intervals or maintain longer historical records. At a 5-minute interval, that's over 347 days of data; at 15-minute intervals, over 1,000 days before data overwrites.
Configure high and low temperature thresholds in the bmLogger app. When readings exceed your limits, you receive instant push notifications to your phone. For 24/7 alerting even when your phone isn't nearby, pair with the BM Gateway for email and SMS alerts.
The CR2477 battery typically lasts up to 5 years under normal use conditions. Battery life depends on the configured logging interval, alert frequency, and environmental conditions. The battery is user-replaceable.
The ±0.1°C accuracy meets stringent requirements for pharmaceutical storage (GDP compliance), vaccine cold chain (CDC VFC program), blood bank refrigerators, and laboratory freezers where precise temperature documentation is mandatory for regulatory audits.
Yes, the Tempo Disc Maxi Alert operates from -40°C to +125°C (-40°F to +257°F), covering everything from ultra-low freezers to high-temperature storage. The Sensirion STS4x sensor maintains accuracy across this full range.
Yes, the Tempo Disc Maxi Alert is fully compatible with the BM Gateway. Connect to bmCloud for 24/7 remote monitoring, automatic data logging, email/SMS alerts, and multi-user access from anywhere in the world.
