Description
The TM-41x Series measures air speed, temperature and humidity. These instruments are ideal for spot measurements at air outlets on account of their 45mm vane. In addition to air speed and temperature, also measures air moisture and absolute pressure. In this way, air conditioning systems can be reliably checked.
