PCE Instruments PCE-HT 71N-ICA USB data logger for long-term measurement of temperature and relative humidity, resolution 0.1 H.r./°C
(Incl. Tax: €292.18)
The PCE Instruments PCE-HT 71N-ICA is a compact USB data logger designed for long-term monitoring of temperature and relative humidity. It records measurements autonomously into a 32K internal memory, with a user-adjustable sampling rate, and transfers logged data to a PC via USB for analysis. The included software supports full reporting and dew point calculation. Powered by a long-life 3.6 V lithium battery (replaceable) and supplied with ISO certification.
The PCE-HT 71N-ICA USB data logger measures and stores relative humidity and temperature using internal sensors, providing reliable traceability for controlled environments and cold-chain applications. It is widely used in supermarket refrigerated displays, cold transport, warehouses, and air-conditioned server/IT rooms.
The logger can be started manually or fully scheduled (start/stop time, date, and sampling interval) and left to record autonomously. After USB transfer, data can be reviewed with the included software, which also enables dew point calculation. Thanks to non-volatile EEPROM memory and LED status indication (logging/alarm), monitoring is straightforward. The replaceable 3.6 V lithium battery can last up to about one year, depending on usage. ISO certificate included.
