12 best meter gauges

Meter gauges are instruments used in the field of dimensional measurement, particularly in industrial and scientific applications. They are designed to accurately measure and verify the dimensions of objects or parts, ensuring they meet specific size and tolerance requirements.

There are various types of meter gauges, each suited for different purposes:

  1. Dial Indicator Gauges: These gauges use a dial or digital display to indicate measurements. They are often used in machining and manufacturing processes to check the accuracy of cuts, drills, and other operations.

  2. Vernier Calipers: A vernier caliper is a precise measuring instrument that can measure internal and external dimensions with high accuracy. It consists of a main scale and a sliding vernier scale, allowing for direct readings.

  3. Micrometers: Micrometers are highly accurate instruments used to measure small distances, typically in the range of millimeters to micrometers. They consist of a calibrated screw that moves a spindle perpendicular to the object being measured.

  4. Height Gauges: These gauges are used to measure the vertical distance between the base and a reference point on the object. They are commonly used in machining and inspection processes.

  5. Thread Gauges: Thread gauges are used to measure the pitch diameter and thread angle of screws, bolts, and other threaded objects. They ensure that the threads meet the required specifications.

  6. Bore Gauges: Bore gauges are used to measure the inside diameter of holes or bores. They can be either fixed or adjustable, depending on the specific application.

  7. Plug Gauges: These gauges are used to check the dimensions of holes for size and roundness. They come in a variety of designs, including single-ended and double-ended.

  8. Ring Gauges: Ring gauges are used to check the external dimensions of cylindrical objects. They are typically used to verify the diameter and roundness of shafts.

  9. Snap Gauges: Snap gauges are used for rapid measurement of external dimensions. They consist of a go and no-go gauge, allowing for quick verification of parts.

  10. Pressure Gauges: While not strictly for dimensional measurement, pressure gauges are used to measure pressure in various industrial processes. They are important for ensuring that systems operate within safe limits.

Meter gauges are crucial tools in quality control and assurance processes in industries such as manufacturing, automotive, aerospace, and engineering. They play a vital role in maintaining precision and accuracy in the production of components and parts.

Keep in mind that while these descriptions provide a general overview of meter gauges, specific designs and applications may vary depending on the industry and intended use. It's important to refer to the manufacturer's guidelines and industry standards for precise information on the operation and application of specific meter gauges.

User questions & answers

Question: What is the accuracy of this unit
Answer: I personally have not verified the accuracy of this product. I use the meter as a qualitative result as opposed to quantitative result. I can verify that the meter I received was functional. I tested against a fake led uvc bulb (all of these style bulbs are fake) there was no result. I ordered a different uvc bulb (fluorescent) from a more reputable source and the meter yielded expected results. I hope this helps.
Question: do I have to calibrate it often
Answer: Yes it detects and measure UVC light output in uW/cm2 but not in wavelength
Question: Will this accurately measure paint thickness on fiberglass body cars i.e. Corvettes
Answer: RGM_UVC meter does not have a remote sensor. I did not see the review that mentioned remote sensor so I cannot comment on whether the review was for a different product. Good meter for the price. Not a calibrated instrument but does show presence of UV-C. Checked against a UV-C diode detector.
Question: Buyers---is the instructional manual for the gauge useful
Answer: Sorry, it does not.

User questions & answers

Question: Can i reset the comfort range? 79 degrees f is much too high to be comfortable imo
Answer: Actually the temp does have a bearing on the comfort indicator as amorina states. It will need to be a minimum of 20 degrees and between 50 and 70% humidity to indicate as comfortable. I agree with you that this is a little high and perhaps 18 would be ok. Other sources state that 40% humidity is ideal so who knows!I think just go with what feels right. In answer to your question though unfortunately the comfort range can not be reset or altered.
Question: is this made in usa
Answer: In China. I bought 3 of them, but don't find them useful. The setting for humid, dry, comfort is inaccurate for a relativity level reading in a home environment. At least in the Midwest region. They say 49% is dry when in fact it's too much for a home to carry, at least in the winter colder temps.
Question: Has anyone had this long enough to know if the battery will last at least one year
Answer: This is probably too late to be of use to the original poster, but maybe it will help someone. I purchased mine in March of '17 and the unit just died on me this past weekend, I was still using the original battery. I changed the battery and the thermometer was still dead, but that's less than $10 for nearly 2 years of service on a single battery.
Question: Any way to calibrate temperature
Answer: Calibrate means that you adjust your measuring tool (e.g. thermometer, hygrometer, speedometer, etc.) to give a known value when it's measuring (detecting) that value; you usually do this by adjusting a screw or other mechanism that results in the unit showing a 'reading', or measurement, of that known value on its display or output. This unit does NOT have any calibration adjustment.

User questions & answers

Question: we are looking for something more non metal, any recommendations
Answer: Amperage is measured independently of voltage, so the answer to your question is "no." As long the display is powered within the stated "5-120V," amperage shown will be just fine.
Question: we are looking for something more non metal, any recommendations
Answer: I don't see why not. The hole through the Hall Effect Sensor is 3/4-inch diameter. My wire chart shows a 1/0 THHN or THWN is 0.491 inches O.D. This seems pretty heavy for DC current, but it ought to work as long as your supply voltage is within the required 5-100 Volts DC.

User questions & answers

Question: How does it hook up
Answer: This is for measuring DC voltage and amperage. Not for 110 volts AC current.
Question: Does it turn off when the car turns off
Answer: You do not need a switch to power the ammeter but you would need to disconnect the battery to avoid draining the battery when not in use. My choice was to add a small toggle switch so I wouldn't need to remove the 9 V battery each time I used the circuit. For me, it is just more convenient to flip the switch or push a push-button switch when needed.
Question: Can you hook it up to or amp
Answer: I don't know the temperature of a diesel engine. Here is the Operating temperature: -4°F - 140°F (-20°C - 60°C) . So the environment temperature should not be over 140°F.
Question: What size inline fuse to run with this when I put a toggle on it, I want it to power on and off via a toggle switch
Answer: Not sure about the 400a version, but the 100a version has two sensor wires. One short one about 6-8" long, and a longer one about 5-6 ft long. I've purchased wire and extended the sensor wire to 20 ft. and it still works well and accurately.
