The HH311 is a low cost, high performance handheld meter. It offers a triple display to show the temperature and humidity from a handheld probe and can display data from a separate K type thermocouple connected via a standard SMP type miniature connector to the T2 input. The temperature/humidity probe uses a semiconductor and polymer capacitive sensor. An optional software package is offered to allow data to be read by a PC through the RS232 port.

Rated 5 out of 5 by from Well designed and packaged I purchased this last week and am very satisfied that I did. Works well. Easy to use. It appears that the reading is accurate. The unit came with a RS232 connector for data logging. Software included.
