설명The RHXL5SD is a low cost, high performance handheld temperature and humidity meter with data logging capability. It offers a four variable display to show the temperature and humidity form a handheld probe and a separate K type thermocouple connected via a standard SMP type miniature connector to the T2 input along with a real time clock. High and Lo alarms can be set to T1, T2, and RH inputs. The temperature/humidity probe uses a semiconductor and polymer capacitive sensor. Because the RHXL5SD is microprocessor-based, it can make full use of the portability, reliability, and large storage capacities that SD memory cards offer. Measurements can be made automatically at any sampling rate between 5 seconds and 1 hour, or manually.
