Vaisala HMP1 RH&T Probe
The purpose of the Vaisala HMP1 is to measure indoor ambient conditions. For general laboratory applications, the Vaisala HMP1 can be immediately linked to an Indigo200 series transmitter; for more demanding, industrial installations, the Vaisala Indigo 500 Series transmitter can be used. The probe head houses the electronics and calibration. The integrated probe has a 5 mm diameter and is made to react quickly. The sensor is the well-known HUMICAP®, which provides stability and dependability over time.
The Vaisala HMP1 can be utilized as a standalone digital Modbus RTU transmitter via RS-485 serial bus in addition to indigo interaction. Vaisala Insight PC Software, which enables data visualization and calibration, can be used to setup it. As standard, Vaisala HMP1 probes include a manufacturer calibration certificate.
