The Elitech DR-230-THDE is a Bluetooth hygrometer thermometer and reusable temperature recorder data logger featuring a large screen and dual external temperature and humidity sensors. Designed for precision monitoring, it captures environmental conditions across a wide range of applications, from cold chain logistics to server rooms and greenhouses. The built-in Bluetooth connectivity enables seamless pairing with mobile devices for real-time data access and configuration. Its large, clear display presents current readings, min/max values, and alarm status at a glance, reducing the need for constant manual checks. This device employs two external probes, each capable of measuring temperature and humidity simultaneously, allowing users to monitor two distinct locations or compare ambient with spot conditions.

The sensors deliver accurate readings with typical temperature tolerance of ±0.5°C and humidity tolerance of ±3% RH, ensuring reliable data for sensitive goods. The robust ABS plastic housing withstands minor impacts and dust ingress, making it suitable for industrial and commercial environments. Internal components are designed for low power consumption, extending battery life over months of continuous logging when used with typical intervals. Data storage capacity reaches up to 40, 000 records per unit, with the ability to export logged history via Bluetooth to a companion app or software.

The logging interval is user‑adjustable from one second to 24 hours, offering flexibility for short‑term tests or long‑term trend analysis. Alarms can be set for high/low thresholds, triggering visual and audible alerts when conditions deviate. The reusable nature of the device adds cost‑effectiveness: after each deployment, data can be cleared, and the logger is ready for the next cycle. No proprietary cables or dongles are required for data retrieval, simplifying workflow.

The DR-230-THDE excels in environments where dual‑zone monitoring is critical, such as pharmaceutical storage, food transportation, museum archives, and HVAC system validation. Its portability and wireless connectivity reduce setup time, while the external sensors can be placed in hard‑to‑reach areas without moving the main unit. The companion software supports CSV export for easy integration into spreadsheets or compliance reports, and the Bluetooth range of approximately 10 to 30 meters (open space) provides convenient access from a distance. For continuous logging, the internal memory retains data even if Bluetooth connection is temporarily lost, ensuring no gaps in the record.

At a price point of $38.75, this device delivers professional‑grade functionality at an accessible cost, offering substantial savings compared to multi‑unit or wired alternatives. Its combination of dual external sensors, large display, and Bluetooth data export makes it a practical choice for businesses and individuals seeking reliable environmental monitoring without recurring expenses. The build quality and component selection support repeated use across projects, reinforcing its value as a long‑term tool. For users requiring accurate, dual‑zone temperature and humidity logging with modern connectivity, this logger represents a solid investment that balances performance and affordability.
