If no uv or infred, why include meter?

to see if it has proper amount of light that transfers as sunlight. not real accurate but will suffice in a pinch.

Whether or not you need to compensate for exposure will depend on your metering system. If you have a recently new camera (DSLR or mirrorless) with metering through the lens the answer is probably no. You should do some practice shots however to see the results. You may want to use a compensation factor to fine tune your exposure but probably not mandatory. However, if you have an older meter (hand held) or on the camera body but not through the lens, yes you must compensate as you would with any filter not directly exposed to the meter.

No, the meter does everything as expected. One thing is, you should make sure that the probes are clean and dry before testing each time you take a reading.Bob

As best I understand the question, this sort of comparison is just what the meter is meant to do: measure light intensity. What you read is what you got. Regards,AC

Control solution is recommended but is actually rarely used. I have only used it when I questioned the results I was getting from a previous meter. All meter manufacturers state that you should use control solution regularly, but very few people actually do. I think thank the manufacturers recommend it to CYA.

Yes. The meter comes with a bottle of control solution to initially setup up the meter and to use anytime you feel like the readings are too high/low. :-)

You can order one that is calibrated. Meters typically do not come from the factory with NIST calibration certs. It is best to have them calibrated locally.

I bought this meter, too. I think that you probably have someone else do the work you intended to do if you need a manual for an analog mm. Very simple and straight forward meter that does not require a manual.

Leaving it in the soil will compromise the meter. It is not designed for that purpose.

You don't need it unless you are growing inside of a tent where the unit can be vented. Plants grow better with UV exposure. The glass separates a lot of UV.

No!! Use it inside. There are some things I think are lacking on this meter. But when I check my system the first thing I check is the voltage and amps on this meter. I have several meters that are always on. This one is the easiest. Dan

comes with no wires or connectors.You wiil have to find hot wire on existing wiring and find ground, meter is not sensitive to ground or plus.

The meter is water resistant. It is suitable for any equipment exposed to the elements.

I installed this in my son's bathroom to control mildew. I did not need any other sensors. At the same time I installed a UV light. The mildew is gone but I do not know if one or both fixed the problem.

Yes a shunt is necessary to allow the meter to work. I believe it is 500 mA.

This unit measures both the humidity and the temperature, but it displays only the relative humidity, so if you want to know the temperature, you'll need another meter for that. I have a temperature controller next to the humidity meter, so I get temperature off that.

Hello. The UV Light is what creates the reaction with the Titanium Dioxode that gives off the CO2, so you can't have one without the other. Thank you
