Protimeter Hygromaster2 Instruction Manual
1. Introduction
The Protimeter Hygromaster2 is a powerful and versatile thermo-hygrometer.
This product is used to measure relative humidity, air temperature and
surface temperature of structures. Additionally, the difference between dew
point and Surface temperature can also be displayed for condensation risk
assessment applications.
2. Safety Considerations
• IR temperature measurement - Please note that the readings
are indicative readings outside the measurement range of the IR
temperature mode and the accuracy of the measurement is not
guaranteed outside the range.
• Calibration of unit - The accuracy specications of the product are
valid for one year after the date of calibration, and the product requires
recalibration after this period.
Laser pointers are effective tools when used properly, but the following
considerations must be observed when using laser pointers:
• Never look directly into the laser beam.
• Never point a laser beam at a person.
• Do not aim the laser beam at reective surfaces.
• Never view a laser beam using an optical instrument, such as
binoculars or a microscope.
• Do not allow children to use laser pointers unless under the supervision
of an adult.

Protimeter Hygromaster2 Instruction Manual
2. Safety Considerations (cont.)
• Use only laser pointers meeting the following criteria:
• Labeled with FDA certication stating “DANGER: Laser Radiation”
for Class 3R lasers or “CAUTION: Laser Radiation” for Class 2 lasers.
• Classied as Class 2 or 3R according to the label. Do not use Class
3b or Class 4 products.
• Operates at a wavelength between 630 nm and 680 nm.
• Has a maximum output less than 0.4 mW, the lower the better.
3. Product Components and Accessories
The Hygromaster2 instrument measures air temperature, relative humidity
and surface temperature. To measure all the above mentioned parameters,
Hygromaster2 uses different sensors, along with a variety of accessories for
convenient measurements. The following external connectors are found on
the instrument (see Figure1 on page 3):
A - This edge connection socket is for use with a Hygrostick®, Quikstick or
Short Quikstick probe.
B - This jack connection socket is for use with the Direct Contact Surface
Temperature Sensor.
C - This USB socket is for connection to a PC when using the optional
Hygromaster2 logging software.

Figure 1: Connections for Probes and Sensors
• The Hygrostick (POL4750), Quikstick (POL8750), Short Quikstick
(POL8751) and 30cm humidity probes (BLD8755) measure relative
humidity (%RH) and ambient air temperature in rooms or materials. They
can be connected to the Hygromaster2 instrument either directly or by
means of the extension lead.
• The surface temperature sensor is used when investigating condensation
situations.

3.1 Switching the Hygromaster2 ON and OFF
Prior to initial use, ensure that a 9V battery is correctly inserted in the battery
compartment.
Note: The battery status is indicated by an icon on the display. When
the LOW BATTERY message appears, replace the battery.
To switch the Hygromaster2 ON, press the power button momentarily
Note: The Hygromaster2 switches OFF automatically after 2 minutes if no
activity is observed, unless the default settings are changed (see
Section 4.7c, “Auto Off”, on page 17 for instructions).
To switch the instrument OFF immediately, press and hold for at least
3 seconds. Once has been depressed for 3 seconds or more, the text
string SWITCHING OFF THE DEVICE appears on the display. When is
released, the text string disappears and the unit switches OFF
Whenever the battery voltage falls below the threshold value, the battery
symbol starts blinking. If the battery voltage falls below the operating level,
the instrument prompts with the message
LOW BATTERY

4. HYGROMASTER2 Modes
The Protimeter Hygromaster2 instrument measures air temperature, relative
humidity and surface temperature.
4.1 Hygrometer - Selection and Use
Navigate to SELECT MODE -> HYGROMETER and press to select the
Hygrometer mode.
To use the Protimeter Hygromaster2 as a Hygrometer (see Figure 4 on page
11), connect the Hygrostick, Quikstick or Short Quikstick probe into socket A
either directly or indirectly with the extension lead.
Relative humidity and temperature measurements are made with the
Hygrostick, Quikstick or Short Quikstick probe, and the Hygromaster2
Instrument uses these values to calculate a range of psychometric readings.
When using the Hygromaster2 to measure the conditions in air, the humidity
probe is normally connected directly to the instrument. However, when it is
impractical or awkward to use the instrument in this way, the extension lead
may be used to connect the Hygrostick, Quikstick or Short Quikstick to the
instrument. Typically, the extension lead will be used when taking readings
from probes that have been embedded in structures such as walls and oors.

4.1 Hygrometer - Selection and Use (cont.)
Note: For best response time, do not store the Hygromaster2 in excessively hot or
cold locations, such as in a vehicle.
4.2 Psychrometrics - Selection and Use
Navigate to SELECT MODE -> PSYCHROMETRICS and press to select
the Psychrometrics mode.
Connect the Hygrostick, Quikstick or Short Quikstick probe into socket A.
The following parameters are displayed in this mode:
4.2a Dew Point
Navigate to SELECT MODE -> PSYCHROMETRICS -> DEW POINT and
press to get the Dew Point reading.
4.2b Grains per Pound/Grams per Kilogram
Navigate to SELECT MODE -> PSYCHROMETRICS ->
GRAMS PER KILOGRAM/ GRAINS PER POUND and press to get the
Mixing Ratio reading.
4.2c Enthalpy
Navigate to SELECT MODE -> PSYCHROMETRICS -> ENTHALPY and
press to get the Enthalpy reading.
4.2d Vapor Pressure
Navigate to SELECT MODE -> PSYCHROMETRICS -> VAPOR PRESSURE
and press to get the Vapor Pressure reading.
4.2e Custom Psychrometrics

Psychrometric parameters in single screen. Parameters to be displayed can
be set in custom option in settings screen
Navigate to SELECT MODE -> PSYCHROMETRICS -> CUSTOM and press
to get the custom psychrometrics readings.
Note: Change the units in Settings (see page 16) to obtain both metric and
non-metric equivalents.

4.3 Condensator
The Condensator Mode enables the user to assess the risk of condensation
occurring on surfaces or to conrm whether or not condensation is present
On a surface.
The Hygromaster2 can be used as a Condensator using two modes:
4.3a Surface Temperature Probe (Contact Based) - Selection
and Use
Navigate to SELECT MODE -> SURFACE TEMPERATURE PROBE and
press to select the Surface Temperature Probe mode.
In this mode, the Hygromaster2 measures the surface temperature using an
External Surface Temperature probe inserted into socket B and making contact
with the surface to be assessed. In addition to the Surface Temperature probe,
connect a Humidity probe into socket A for the Hygromaster2 to show the
Condensation status.
TDIFF is a useful function when investigating condensation, as it tells
the user how many degrees a surface temperature is above or below the
prevailing dew point temperature.
4.3b Surface Temperature IR (Non-Contact Based) – Selection
and Use
In this mode, the Hygromaster2 measures surface temperature using IR
technology
Connect a humidity probe into socket A.
Hold the button to enable the IR Thermometer. Release the button and
press it again within 1 second to enable the LASER pointer. The LASER
pointer will indicate the area on the surface where the measurement is being
Taken (see Figure 5 on page 14).

4.4 Logging - Selection and Use
The Hygromaster2 supports both continuous and manual logging.
4.4a Manual Logging
If is pressed for 1.5sec at any of the measurement screens, the data and
Timestamp at that instant will be logged and a RECORD SAVED message
will be displayed on the bottom bar.
4.4b Continuous Logging
Continuous logging is used to sample and store data continuously.
Continuous logging is enabled either by setting logging parameters through
the Keypad or through a PC using Logging Software. (see Section 4.7g, “Set
Logging Parameters (Optional PC Logging Software Required)”, on page 19.)
After the logging parameters are saved, logging starts after the START
AFTER minutes have elapsed. The logging icon is displayed on the
top left corner of the screen while logging is active.
When logging is in progress, an option to stop logging is provided under
the SETTINGS menu. Logging can be stopped either by selecting SELECT
MODE -> SETTINGS -> STOP LOGGING in the instrument, by clicking STOP
LOGGING in the Logging Software or when the instrument is turned OFF.
