Frequently asked questions
What is a temperature and humidity data logger?
A temperature and humidity data logger is a small battery-powered instrument that measures and records environmental readings at set intervals, then stores them in onboard memory for download as a report. They're used to prove that conditions stayed within range during storage, transport or a process, without anyone needing to watch a gauge.
What's the difference between a USB and a Bluetooth data logger?
A USB logger, such as the RC-5+ or the YDP series, is plugged into a computer to download its log and generate a PDF or CSV report. A Bluetooth logger, such as the TZ-BT06, broadcasts live readings to a phone app over the air, so the data can be checked without opening the container or shipment it's monitoring.
Which data logger suits cold chain or pharmaceutical transport?
The RC-5+ is built for exactly this: a reusable, IP-rated USB logger with a 32,000-point memory and automatic PDF reporting for refrigerated trucks, cold storage and pharmaceutical shipments. The TZ-BT06 suits the same use case where wireless, in-transit checks are preferred over plugging in a cable.
Can any of these loggers survive autoclave or sterilization cycles?
The YPL-10-S is purpose-built for this: an IP67 metal-bodied logger rated to +125°C with a high-temperature lithium cell, designed for autoclave validation, sterilization runs and other high-heat process monitoring.
Do these data loggers need special software to read the recorded data?
Most generate a standard PDF, CSV or Excel file automatically with no software install, just a USB connection. The YDP and SSNP-700ED ranges also support the free PoChain database software for managing logs across multiple devices, and the TZ-BT06 pairs with a mobile app over Bluetooth.
How long do data logger batteries typically last?
It depends on the model and logging interval. The RC-5+ runs up to 6 months on its coin cell, the TZ-BT06 and YEM-70L are rated around a year, and the SSNP-700ED's lithium cell lasts roughly 3 years at a 15-minute logging interval. Shorter logging intervals draw more power and shorten battery life across all models.
