Product Overview
HMP series probes are humidity and temperature measurement probes with a digital output
(Modbus protocol). The probes are designed for demanding humidity and temperature
measurement applications. Each probe model has a 2 m (6.5 ft) cable between the probe body
and the probe head.
The probes are compatible with Vaisala Indigo transmitters. They can also be connected to
Vaisala Insight software for configuration, diagnostics, and temporary online monitoring.

dew point temperature, wet-bulb temperature, absolute humidity, mixing ratio, water
vapor pressure, enthalpy. Humidity parameters available only on HMP models.
• Sensor purge provides superior chemical resistance (HMP models only)
• Probe and sensor warming functions minimize condensation on probe (HMP models only)
• Traceable calibration certificate:
• HMP models: 5 points for humidity, 1 point for temperature
• TMP1: 2 points for temperature
• Standalone Modbus RTU over RS-485
• Plug & play compatible with Indigo series of transmitters
• Can be connected to Vaisala Insight PC software for configuration, diagnostics, and
temporary online monitoring

Installation
When you choose the installation location for the probe, consider the following:
• Verify the operating environment specification of the probe model. The probe head
typically has a much wider operating temperature range than the probe body.
• If the temperature of the measured environment diers greatly from ambient
temperature, the entire probe head and preferably plenty of cable must be inside the
measured environment. This prevents measurement inaccuracy caused by heat
conduction along the cable.
• Probe mounting options are model-specific.

Figure 2 Example Installation of HMP8 Model
1Mount the probe head horizontally to prevent any water condensing on the probe head
from running to the sensors.
2Let the cable hang loosely to prevent condensed water from running along the cable to
the probe head.
3Attach the probe body to a wall or other surface using the two mounting clips (Vaisala
item 243257SP) supplied with the probe. Each clip attaches to the installation surface with
one screw (screw hole Ø 4.2 mm).
4Cable to Modbus master or Indigo transmitter.

Figure 6 HMP7 Probe Dimensions
Vaisala HUMICAPâHumidity and Temperature Probe HMP7 is designed for applications that
involve constant high humidity or rapid changes in humidity, such as drying and test
chambers, combustion air, and other humidifiers and meteorological measurements, where
measurement performance and chemical tolerance are essential.
• Temperature measurement range -70 ... +180 °C (-94 ... +356 °F)
• Operating temperature range for probe body -40 ... +80 °C (-40 ... +176 °F)
• Probe and sensor warming functions minimize condensation on probe
• Vapor and pressure proof construction
• Stainless steel mesh filter standard in delivery
Probe Heating
HMP7 supports probe heating. Probe heating heats up not only the sensor, but the entire
probe head. When probe temperature is heated above dew point temperature, condensation
on the probe can be avoided while measuring the dew point temperature of the process.
Probe heating is disabled by default. If you enable probe heating, output parameters that are
dependent on temperature measurement (such as relative humidity) are disabled, unless the
true temperature of the measured environment is updated to the temperature compensation
register of the probe from another measurement instrument (for example, the TMP1 probe).
Output parameters such as dew point temperature that can be measured or calculated
without this external temperature information are available even without the temperature
input.

Attaching Probes to Indigo Transmitters
Figure 13 Attaching the Probe to Indigo 200 Series
1. Insert the probe or the connection cable into the transmitter's connector. Use of
connection cable is recommended for strain relief.
2. Turn the locking wheel of the transmitter to lock the probe or cable in place.
Do not turn the probe or the cable itself, as that will damage the connectors.
3. If you are using a connection cable, connect the probe to the cable.
4. When the transmitter recognizes the connected probe, it shows a notification message on
the display.
