This category has the Marmonix USB data loggers for temperature and humidity: the MT-40 and MT-41 single-use temperature loggers, the MHT-50 and MHT-51 single-use temperature and humidity loggers, and the reusable MHT-60B with USB and Bluetooth. Buying from Marmonix means you get the logger direct from the brand, with official datasheets, default 2–8 °C cold-chain alarms, and local supply and support across the UAE and GCC.
Every model records −30 to +70 °C at ±0.5 °C (−20 to +40 °C) and generates a PDF report as soon as it is plugged into a PC (CSV data too on the single-use models), with no software to install. That makes them a simple record for pharma and vaccine distribution, food and fresh-produce shipments, cold rooms, warehouses and laboratories.

How to choose a data logger
What to measure: temperature only (MT-40, MT-41) or temperature and humidity (MHT-50, MHT-51, MHT-60B).
Single-use or reusable: single-use for one-way shipments; reusable for cold rooms, stores and labs.
Display: an LCD (MT-41, MHT-51, MHT-60B) lets the receiver check readings and alarm status before accepting goods (the MHT-51 also shows MAX/MIN/AVG); LED models are smaller and lighter.
Alarm limits and duration: check that the 2–8 °C default suits your product, or set your own limits, interval and trip length.
Report: all models make a PDF report on USB; the MHT-60B can also be read over Bluetooth.
Who uses data loggers
Pharmacies, hospitals and vaccine distributors; food, dairy and fresh-produce exporters; cold-chain logistics and 3PL warehouses; laboratories; and facility teams checking server rooms and storage areas. For spot readings rather than logging, see our thermometers, and read our environmental and physical measurement instruments guide.
Data logger FAQ
Single-use or reusable data logger: which do I need?
Single-use loggers (MT-40, MT-41, MHT-50, MHT-51) travel with a shipment and stay with the receiver as the record, so nothing has to be returned. A reusable logger such as the MHT-60B suits fixed points like cold rooms, pharmacies, warehouses and labs, where you download data and restart it.
Do I need software to read the data?
No. Plug a Marmonix logger into a PC’s USB port and it generates a PDF report automatically; the single-use models also export CSV data. The MHT-60B can also be read over Bluetooth.
What are the default alarm settings?
The single-use loggers ship with a 2–8 °C alarm window for vaccines, pharma and chilled food, and the humidity models also alarm outside 20–80% RH. All limits, the logging interval and the trip length can be customised.
How accurate are Marmonix data loggers?
Temperature accuracy is ±0.5 °C from −20 to +40 °C across the −30 to +70 °C range, with 0.1 °C resolution. The humidity models read 0–100% RH with ±3% RH at 20–80% RH.
How long can a logger record?
The single-use models record for 90 days by default and can be set from 7 to 360 days, with a logging interval from 1 minute to 24 hours (5 minutes by default).
