1 Introduction
Thank you for purchasing a thermo hygrometer from PCE Instruments.
The PCE-G1A measures both relative humidity and temperature. Its large 7-segment LED display with a
figure height of 100 mm makes the measured values easily readable from a distance of up to 50 m. The
thermo hygrometer is IP 54 protected and can be mounted to a wall. The relative humidity and
temperature values are displayed alternately every 5 seconds. The sensors which are calibrated by the
manufacturer are connected to the display by 1 m cables. The passive two-channel analogue output (no
individual power supply!) converts relative humidity and temperature value
s into a 4 … 20 mA signal
before displaying them. The PCE-G1A comes with a screened multipole plug for connection with a
device. An optional ISO calibration certificate can be ordered separately.
Delivery content

2 Safety notes
Please read this manual carefully and completely before you use the device for the first time. The device
may only be used by qualified personnel and repaired by PCE Instruments personnel. There is no
warranty of damages or injuries caused by non-observance of the manual.
- Do not allow the cold humidity sensor to come in contact with warm and humid air. This causes
condensation and totally falsifies the results. Condensation does not damage the sensors nor does it
change its characteristic.
- The humidity sensor is not resistant to acetone or other chemical solvents.
- The device may only be used in the approved temperature range.
-
The case should only be opened by qualified personnel of PCE Instruments.
- The instrument should never be placed with the user interface facing an object (e. g. keyboard side on a
table).
- You should not make any technical changes to the device.
- If the filter or sensors become dusted wash them gently with alcohol and let them dry. Mechanical
cleaning is not allowed as it may damage the filter or cause scratches to the sensors.
