Tempmate B4 Miniature Temperature and Humidity Data loggers with 3-point calibration. Minimum order of 10 units.
Unfortunately, the 100541 has been discontinued, check out our other Temperature Loggers for more options.
The tempmate.-B4 mini data loggers can record up to 4,096 temperature and humidity measurements. The temperature range spans -20°C to +85°C, with an accuracy rate of up to ±0.5°C (temperature) and 5% (humidity). Calibrated at 80°C, +100°C, and +120°C and 11%, 40%, 75%. Minimum order of 10 units.


Each tempmate.-B4 mini data logger can record up to 4,096 temperature and humidity measurements. The temperature range spans -20 C to +85 C, with an accuracy rate of up to +- 0.5 C (temperature) and 5% (humidity). The software also shows dew point and absolute humidity. Thanks to its extremely compact construction (about the size of a watch battery), the logger is extremely versatile.
The logger is connected to the PC via the separately available USB adapter, and is programmed, read and analysed with the aid of the user-friendly TempIT software. The TempIT-Lite software offers a graphical display and can be downloaded here, free of charge.
