Which is the cheapest HMT120 temperature and humidity transmitter

The Vaisala temperature and humidity transmitter HMT120 is designed for humidity and temperature monitoring in cleanrooms, and is also suitable for harsh HVAC and light chemical industries.

Performance, the Vaisala HMT120 adopts Vaisala HUMICAP â technology for accurate and reliable measurement of relative humidity. Vaisala temperature and humidity transmitters are resistant to dust and most chemicals. The transmitter housing has been optimized for use in clean rooms. The surface of the shell is smooth, which makes it easy to clean, and the selected shell material is resistant to purification agents. In addition, wiring can be done through the back panel of the transmitter.

The HMT120 transmitter uses interchangeable relative humidity probes. The probe can be easily removed and replaced with a new probe without the need to adjust the transmitter, allowing users to easily and quickly recalibrate the transmitter. A Vaisala portable instrument can be used as a reference to adjust the probe. It also provides constant output probes with fixed relative humidity and temperature outputs, making it easy to inspect monitoring systems and signal transmission lines.

An optional HMT120 temperature and humidity transmitter can be provided for wall installation or used with a remote probe. In high-temperature environments or limited space, remote probes are an ideal choice. The optional LCD screen displays the measurement results of the selected parameters in the selected unit. The parameters are displayed simultaneously in two separate lines on the display screen.
