2. Product Overview
HMP4, HMP5, HMP7, and HMP8 are humidity and temperature measurement probes with a
digital (Modbus) output. TMP1 is a temperature-only version. The probes are designed for
demanding humidity and temperature measurement applications. Each probe model has a
dierent probe head, but the same probe body and 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.

varies depending on the Indigo transmitter model. For more information on Indigo
transmitters, see www.vaisala.com/indigo.
2.4 Safety
When returning a product for calibration or repair, make sure it
has not been exposed to dangerous contamination, and is safe to handle
without special precautions.
WARNING!
Do not attempt to open the probe body. There are no user
serviceable parts inside the probe body.
CAUTION!
Information on spare parts, accessories, and calibration products is available

2.5 ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to electronic circuits.
Vaisala products are adequately protected against ESD for their intended use. However, it is
possible to damage the product by delivering an electrostatic discharge when touching,
removing or inserting any objects inside the equipment housing.
Avoid touching component contacts or connectors when working with the device.

• 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.

Figure 9 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.
If the temperature of the measured environment diers greatly from ambient
temperature, the whole probe and preferably plenty of cable must be inside the
process. This prevents measurement inaccuracy caused by heat conduction along
the cable.

Vaisala Insight software is a configuration software for Indigo-compatible devices. The
supported operating systems are Windows 7 (64-bit), Windows 8.1 (64-bit), and Windows 10
(64-bit).
With the Insight software, you can:
• See probe information and status
• See real-time measurement
• Calibrate and adjust the probe
•Configure probe features such as measurement filtering, chemical purge, heating, and
serial communication
Download Vaisala Insight software at www.vaisala.com/insight.
The probe can be connected to Vaisala Insight software using a Vaisala USB cable (no.
242659).
4.2 Connecting to Insight Software
• Computer with Vaisala Insight software installed
• USB connection cable (no. 242659)
Figure 11 Connecting Probe to Insight
1. Open the Insight software.
2. Connect the USB cable to a free USB port on the PC.
3. Connect the probe to the USB cable.
4. Wait for Insight software to detect the probe.

4.3 Configuration Options
Select > Configure Device to access configuration options in Insight software.
The available configuration options in correspond to the Modbus configuration registers; see
A.4.2 Configuration Registers (page 50). Insight software is the recommended way to change

The probe can be connected to Vaisala Indigo transmitters, either directly on the transmitter
from the probe's connector, or by using a cable between Indigo and the probe.
Indigo transmitters are host devices that extend the feature set of connected probes with a
range of additional options for outputs, configuration access, measurement viewing, and
status monitoring.
The selection of available additional features (for example, output and connectivity options)
varies depending on the Indigo transmitter model. Depending on the model, a display is
available as an optional selection or as a standard feature. In the non-display model, an LED
indicator is used for notifications.
