4 best drok light meters

Drok is a brand known for producing electronic components and measurement instruments, including light meters. A light meter, in general, is a device used to measure the intensity of light in a given area. It's commonly used in photography, cinematography, and various industries where proper lighting is crucial.

Drok light meters are designed to measure luminance or illuminance, providing accurate readings to assess the brightness levels in a particular environment.These devices typically feature a sensor that captures the incident light, and the readings are displayed on a digital or analog gauge. The data obtained from a light meter can be useful for ensuring proper lighting conditions for tasks like photography, cinematography, or in areas where specific light levels are required for safety or productivity.

It's important to note that while Drok is known for its electronic components and measurement instruments, specific features and models of their light meters can vary. It's advisable to refer to the product specifications and user manuals provided by Drok for detailed information about a particular light meter model, including its range, accuracy, and any additional features it may offer.

In the context of replacement parts and automotive applications, Drok may also produce other electrical components, gauges, and voltmeters that cater to the needs of individuals working with automotive electronics.

User questions & answers

Question:	What is the rated amperage, NOT the current draw, for the voltage indicator
Answer:	Reads RMS watts and will read on sideband
Question:	Is this suitable for outside use
Answer:	12vdc Power cord is included with the meter.
Question:	I am looking to measure the output voltage of a Variable frequency drive three phase no neutral circuit what are the recommendations to wiring
Answer:	The antenna is needed to check the swr between your CB antenna and meter. It is needed in order to set the swr's at its lowest point possible. Rule of thumb when installing a CB radio a good ground or magnetic mount is best, also cables should be in increments of 3 ft. if your distance is 5 feet use a 6 foot cable. This will give you the best ratios.
Question:	Will these read the ac output from a 12vdc to 120vac modified sine wave inverter (ie - does it read rms value)? thanks in advance
Answer:	SW-114 can test Radio RF output : RF Power : 0-10WATT / 0-100WATT

User questions & answers

Question:	my inverter has 2 plugins, 1 is 3 prong 110 and the other 4 prong 220, what i need is a 4 prong 220 unit, has anyone seen such? Thank you
Answer:	It is almost. I leave for a few seconds for it to take reading.
Question:	does the display have a floating decimal point? Or is it fixed? Ex 120.3 volts? Thanks
Answer:	I think this tester can only test soil. And it is written in the description of the seller. I have used it for a month, and I think the measurement results are accurate.
Question:	Does this save max and min voltage values
Answer:	It says it is included - - I've used these for years and never even realized they had batteries, but now that I think about it, 'something' has to make it work, and work it does. My scale came loose and slipped down and still I could test with it, but did buy this new one which works very well! Obviously it wouldn't work (now that I see this) without a battery but it is included so see no problem.
Question:	Is this a true RMS AC voltmeter
Answer:	I used it outdoors to test whether the sun is too strong.

User questions & answers

Question:	can this remain hooked up while the battery is being charged
Answer:	No
Question:	Is there a way of dimming the display? It is just a bit too bright
Answer:	I connected the Drok to a 14 ah MC battery that was failing, it has been attached to the battery for three days, with 0 voltage drop., tied in a single LED, over night the battery dropped to 12.3,..disconnected the LED and it climbed back to 12.5 and stayed there for two more days.... I will put a amp meter in line to see what it draws when I get a chance, but it is very near 0......
Question:	Does this meter come with a bracket to mount the meter
Answer:	In a car it will measure internal temp It measures around the probe. I use it in the dash of my motorcycle for the temp outside when I'm riding
Question:	What's the amp draw or wattage
Answer:	The sensor has to be on the outside on my car. The sensor has to be able to sense the air temp. inside your car. It is not for outside air temp. however.
