जाँच में तापमान देखते हैं।

It is a noun here. जाँच means examination, check, inspection, or checkup.

A learner might expect a verb because it comes from the verb जाँचना meaning to examine / to inspect / to check. But in this sentence, जाँच में means in the examination / during the checkup, so जाँच is functioning as a thing, not as the main action.

If it were a verb, you would expect something like जाँचते हैं.

Here में means in, during, or as part of.

So जाँच में means something like:

• in the checkup
• during the examination
• as part of the inspection

This is a very common use of में in Hindi. It does not only mean physical inside; it can also mark the context or situation in which something happens.

Because तापमान is the direct object, and with an inanimate thing like temperature, Hindi often does not use को.

So तापमान देखते हैं is natural.

In Hindi, को is often omitted with:

• inanimate objects
• general or non-personal objects
• many common verb-object combinations

You can sometimes add को for emphasis or contrast, but here it would usually sound less neutral. The plain form तापमान देखते हैं is the normal way to say it.

Because the subject is not stated, and the verb is agreeing with that implied subject, not with तापमान.

This is important: in this kind of sentence, the verb does not agree with the object तापमान. It agrees with whoever is doing the action.

देखते हैं can match several possible subjects, such as:

• हम = we
• वे = they
• आप = you (polite)
• an honorific singular subject like डॉक्टर = the doctor

So the sentence could mean:

• we check the temperature
• they check the temperature
• the doctor checks the temperature
• you check the temperature

depending on context.

The subject is omitted, which is very common in Hindi.

Hindi often leaves out pronouns and even nouns when the context already makes the subject clear. So this sentence does not explicitly say who checks the temperature.

You have to get that from context. For example, it could be:

• डॉक्टर जाँच में तापमान देखते हैं।
• हम जाँच में तापमान देखते हैं।
• वे जाँच में तापमान देखते हैं।

Without context, देखते हैं just tells you that the subject is probably plural, mixed-gender, or a polite/honorific singular.

Not exactly in the basic English sense of see with your eyes. Here देखना is being used in a broader, very common Hindi way meaning:

• to look at
• to check
• to examine
• to inspect

So तापमान देखते हैं means check the temperature or look at the temperature reading, not just see temperature in a literal visual sense.

Hindi uses देखना very often in places where English prefers check.

It is in the simple present / habitual present: देखते हैं.

That form is commonly used for:

• routines
• general procedures
• repeated actions
• descriptions of what is normally done

So it fits well with something like a medical checkup or a standard procedure.

If you specifically wanted are checking right now, you would usually use the continuous form:

तापमान देख रहे हैं।

But the simple present is very natural when describing what people do as part of a process.

Hindi word order is flexible, but the most neutral pattern is often:

context + object + verb

So here:

• जाँच में = sets the context
• तापमान = the thing being checked
• देखते हैं = the action

This makes the sentence sound natural and organized: first the situation, then what is checked, then the verb.

Other orders are possible in Hindi, but they usually change the emphasis. For example, moving तापमान earlier might put extra focus on it.

Sometimes, yes.

If you want to be very precise about measuring temperature, then:

• तापमान मापते हैं
• तापमान नापते हैं

can be more exact.

But तापमान देखते हैं is still quite natural if the meaning is check the temperature or look at the reading. In everyday Hindi, देखना is often used broadly for checking values, reports, symptoms, and so on.

So:

• मापते/नापते हैं = more specifically measure
• देखते हैं = more generally check/look at

Yes. In natural English, during the examination is often the best way to understand it.

Hindi में can sometimes translate awkwardly if you turn it into English too literally every time. So although में is literally in, in this sentence the most natural sense is often:

• during the checkup
• as part of the examination
• in the course of the inspection

That is a very normal thing in translation between Hindi and English.
