1 Introduction

Thank you for purchasing a hygrometer PCE-555 from PCE Instruments.

This digital humidity and temperature meter which can also measure the wet bulb temperature and the

dew point temperature is commonly used in laboratories, in the construction industry, in building

technology, in different industrial sectors and in engineering. It is also very useful in the areas of

transportation and storage of food as it supports the prevention of mould. Since this hygrometer is quick

and compact, it can easily be used on-site.

5 Instructions

5.1 To switch on the device

Switch the device on by means of the On/Off key (5).

5.2 To select the temperature to be measured and the unit

Press the °F / °C / WBT / Dew Point selection key (4) to select between temperature, dew point

temperature or wet bulb temperature and to choose a unit. Press and hold the key until the desired

temperature to be measured appears along with the correct unit. The possible selections appear in the

following order: °C °F °C Dewpoint °F Dewpoint °C Wet Bulb °F Wet Bulb.

5.3 Humidity and ambient temperature measurement

1. Target the probe (1) at the area which you would like to measure and wait until the values have

stabilised.

2. Read the relative humidity, the values for the ambient temperature, the dew point temperature and the

wet bulb temperature which are indicated in the display (2).

Note: Do not immerse the probe in liquids as it is only suitable for air.

5.4 MAX / MIN function

1. Select the desired temperature to be measured and unit before activating the MAX / MIN function.

2. Press the MAX / MIN key to enter the MAX / MIN recording mode.

3. If you press the key once, MAX is selected and if you press it twice, MIN is selected. The device will

save the highest or the lowest value measured during the time between activation and deactivation of

the MAX / MIN function.

4. Press and hold the key for more than 2 seconds to finish the MAX / MIN recording.

5.5 To freeze / hold the reading

Press the HOLD / key (6) to hold the reading in the display. If you press this key again, you will return

to normal measurement mode.

5.6 To switch the backlight on and off

Press and hold the HOLD / key (6) for more than 2 seconds to switch the backlight on or off.

5.7 Automatic Power Off

To save battery voltage, the device is equipped with an Automatic Power Off function. The device
