The temperature and humidity meter price of the external probe is higher than that of the built-in probe because the external probe temperature and humidity meter has one more line and sensor housing than the built-in probe, increasing the cost of raw materials. And because of the probe external, greatly increase the production time, but also increased production costs.

The built-in probe consumes very low power and also reduces the sensor's stability due to external factors such as aging, vibration and volatile chemical gases. However, due to the sensor probe built-in instrument, the working instrument in the digital tube heating impact measurement, so the built-in probe temperature hygrometer measurement will be disturbed by their own interference, resulting in a little deviation.

The advantage of an external probe is that the measuring range is wider than that of the built-in sensor, which is not connected to the display and the circuit part. However, because the temperature hygrometer of the external probe requires a line connection, and the line has a temperature coefficient, the longer the external sensor line, the greater the error.

Built-in probes don't see sensors from the outside, and they naturally look more generous and beautiful, and are suitable for use in large spaces such as data centers, smart buildings, warehouses, clean rooms, laboratories, and more.

Because the external probe sensor is not suitable for measuring relatively small spaces with the display and circuit parts, such as drying boxes, constant temperature and humidity boxes, refrigerators, etc.
