A technical instrument or apparatus used to determine and display a physical quantity such as temperature, length, pressure, or voltage.
example
Der Elektriker benutzte ein Messgerät, um die Spannung in der Steckdose zu prüfen.
The electrician used a measuring device to check the voltage in the outlet.
Usage tips
Word composition
The word is composed of the verb 'messen' (to measure) and the noun 'das Gerät' (device). The 's' in the middle is a linking s that connects the two parts. Literally, then, it is a device for measuring.
EXAMPLE
Für diese präzise Aufgabe benötigen wir ein spezielles Messgerät.
For this precise task, we need a special measuring device.
Productive compounds
'Messgerät' (measuring device) is a base word for many specific instruments. You form new words by placing the quantity to be measured before it, e.g. 'Blutdruckmessgerät' (blood pressure monitor), 'Geschwindigkeitsmessgerät' (speed measuring device), or 'Temperaturmessgerät' (temperature measuring device).
EXAMPLE
Die Krankenschwester legte mir das Blutdruckmessgerät an.
The nurse put the blood pressure monitor on me.
Use with prepositions
To indicate the purpose of the device, you use the preposition 'für' with the accusative. To express what you measure with, you use 'mit' and the dative.
EXAMPLE
Gibt es ein Messgerät für die Luftfeuchtigkeit?
Is there a measuring device for humidity?

Messgerät vs Lehre
apprenticeship / doctrine
'die Lehre' and 'das Messgerät' can both be technical tools used to check measurements. The difference lies in the type of checking. A 'Lehre' is usually a template or inspection tool: it shows whether a part has the right shape or size. A 'Messgerät' measures a value and displays it, for example temperature, length, pressure, or voltage. Learners may confuse the words because both occur in workshop and technical contexts. If you are only checking whether something fits, you say 'Lehre'; if an exact value is measured and displayed, you say 'Messgerät'.
Messgerät
Das Messgerät zeigt an, wie hoch die Spannung in der Leitung ist.
The measuring device shows how high the voltage is in the line.
Lehre
Bei der Arbeit prüft das Team das Metallteil mit einer Lehre.
At work, the team checks the metal part with a gauge.
