THE Vaisala hand-held HMI41 humidity and temperature indicator is versatile and easy-to-use, and comes with a choice of five different probes.
The indicator also includes a calibration option: by using the suitable probe most Vaisala humidity transmitters can be calibrated at one point quickly and easily.
The HMP41 probe is mounted directly on the indicator and the HMP45 probe has a cable for measurements in ducts or chambers.
The HMP46 probe's structure is solid and rugged; it is designed for measurements in high temperatures and also due to its long shaft measurements from otherwise unreachable places can be taken.
The HMP42 is the thinnest probe in the market today, its diameter being only 4mm. The small probe enables structural humidity measurements from very small spaces.
