User 's Manual

Temperature and humidity probe HMP1 is designed for environmental measurement in indoor space.The HMP1 can be connected directly to the Indigo200 series transmitters to form a single wall unit. The probe and body are integrated in a single unit and use a miniature HUMICAP® sensor with a diameter of 5 mm (0.2 in) for excellent stability and fast response time.

Features:

• ? It is suitable for wall installation when combined with Indigo series transmitter
• ? Relative humidity (RH) accuracy up to ± 1%RH, temperature accuracy up to 0.2 °C (0.36 °F)
• ? Temperature measuring range -40... +60 °C (-40... +140 °F)
• ? Chemical removal ensures good chemical tolerance
  
• ? Support RS-485 Modbus RTU communication protocol, provide a variety of flexible connection mode
• ? Traceable calibration certificates are provided :6 humidity calibration points and 1 temperature calibration point

Main Advantages:

Use Indigo series transmitters for wall installation:

The HMP1 is part of the Vaisala Indigo family, so it can also be used with the Vaisala Indigo500 and Indigo200 transmitters to form a wall mounted transmitter. The transmitter also has additional features such as a display that visually presents data, easy access for probe configuration, and more options for automation system connections, power voltage, and wiring.

When using the HMP1 on its own or with the Indigo transmitter, it can be connected to the free Vaisala Insight computer software for easy field calibration, probe configuration and device analysis.

Fast response time and good measurement performance：

The probe and ontology of HMP1 are integrated in a single unit. The HMP1 uses the same miniature HUMICAP® sensors and probes as the HMP9. This compact probe ensures fast response time and excellent measurement performance even in rapidly changing environments.

Chemical removal greatly reduces the impact of contaminants：

In environments with high concentrations of chemicals and cleaners, the chemical removal option helps maintain measurement accuracy between calibration intervals. Chemical removal The sensor can be heated to remove harmful chemicals. The function can be started manually or by the program at a set interval.
