Frequently Asked Questions

The Disc Maxi 3-in-1 uses the Sensirion SHT4x sensor, one of the most accurate temperature and humidity sensors available. The ±0.1°C accuracy is critical for pharmaceutical cold chain, vaccine storage, and laboratory applications where small temperature variations can affect product integrity.

The Disc Maxi 3-in-1 stores up to 50,000 readings in a circular buffer—double the capacity of the 4-in-1 model. At a 15-minute logging interval, this provides over 520 days of continuous data storage before older readings are overwritten.

Dew point is the temperature at which moisture in the air condenses. Monitoring dew point helps prevent condensation damage in storage facilities, museums, data centers, and any environment where moisture control is critical. The sensor calculates dew point automatically from temperature and humidity readings.

The CR2477 battery typically lasts up to 5 years under normal use conditions. Battery life depends on the configured logging interval and environmental conditions. The battery is user-replaceable.

Yes, the bmLogger mobile app allows you to configure high and low threshold alerts for temperature, humidity, and dew point. You'll receive push notifications when any reading exceeds your set limits.

Yes, the Disc Maxi 3-in-1 is ideal for pharmaceutical cold chain and vaccine storage. With ±0.1°C accuracy, 50,000 data points, configurable alerts, and optional calibration certificates for regulatory compliance, it meets the requirements for GDP, CDC VFC, and WHO guidelines.

Yes, the Disc Maxi 3-in-1 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—ideal for facilities requiring continuous oversight.
