GSM-100E is using the normal temperature probe, the measuring range of its internal probe is -30~+65°C, and external probe is -40~+125°C.

On the basic of GSM-100E, GSM-200E added the humidify measuring function. Therefore it needs to be used with an external temperature and humidity probe. Therefore it needs to be used with an external temperature and humidity probe.

On the basic of GSM-100E, GSM-700E optimized its principle, and increased the measuring range of the external probe. The measuring range of its internal temperature probe is -30~+65°C, and its external temperature probe is increased to -200~+250°C.
