Supported Applications

The Omega HHG191 is a handheld Magnetic Field Meter designed to measure electromagnetic fields (EMF) of extremely low frequency (ELF) ranging from 30 to 300 Hz. The series measures electromagnetic field radiation intensity from various electrical appliances, including power lines, microwave ovens, air conditioners, refrigerators, computer monitors, and audio/video devices.

Operating Conditions & Performance

The HHG191 displays readings in micro-Tesla (µT) or milli-Gauss (mG). The documented measurement ranges include 20 µT, 200 µT, 2000 µT, 20 mG, 200 mG, and 2000 mG. An overload condition is indicated by 'OL' on the left side of the display; users should select a higher range in this instance. A reading lower than 0.5mG may be due to environmental factors rather than a malfunction.

Configuration Options

The HHG191 features an LCD and is powered by battery, with low battery detection indicated by a battery icon on the display. Functional capabilities include:

  • Data hold function to permanently lock readings (press HOLD again to unlock).
  • Maximum hold function to retain the maximum value encountered.
  • Range selection via dedicated button.
  • Unit selection between mG and µT.

The device includes a sensor position, power on/off switch, battery cover, and buttons for unit and range selection. The meter is made in Taiwan and carries CE, ISO 9001, and ISO 9002 certifications.

Key Product Differences

The HHG191 series consists of a single handheld model configured with the features described above. No alternative housings, sensor types, or output configurations are documented for this specific series in the provided source material.

Could this be set up with a computer to record readings continuously over a period of time?

Asked by: Ed98
Hi, thanks for your question. The HHG191 Handheld Gauss meter does not have an output, so unfortunately it cannot be used to stream data to a computer. It is only a read and view result measurement device. Please contact us with any further questions.

Can this measure the residual magnetism of a tape head? Can it be fitted with a probe? Thank you.

Asked by: Artie
The HHG191 is used for measurement of electromagnetic fields only not static or residual field strength. These would have the integrated sensor, and a remote probe is unfortunately not an option. Please contact our Tech Support if you need any further assistance. Thanks

Does it require calibration? Or, what's calibration procedure?

Asked by: aquikclick
There isn't any calibration offered on the HHG191 or procedures for field calibration. It would be best to return the unit on our exchange program for a new unit when your company requires to do calibration or it appears to not be measuring correctly.

If the probe is pointing in the opposite direction of the meter, will the field read as negative? Or does the meter only read magnitude? Thanks.

Asked by: graff
The HHG191 will measure the magnitude of an electro-magnetic energy when the sensing portion of the meter is within field. It has to be orientated into the field and will not measure negative values.

Can this be used to measure the strength of an electromagnet on a machine tool? We use them to hold the parts in place, and have not had a good way of determining if there are "dead" spots, etc.

Asked by: mattr
Its is best to call our Tech Support at 203-359-1660 to review and discus your application needs.

Will this meter provide information regarding frequency and intensity of settings on PEMF device?

Asked by: Confused
The HHG191 will show the unit of measure and range setting on the display. If you use the MAX button it will show the highest magnitude measured once engaged.

Would this be appropriate for testing the strength of a magnet?

Asked by: Amyy
The HHG191 is for measuring magnetic fields created in AC Voltage powered devices and will not measure permanent magnets.

Hi, I'm wondering if this has a wire lead on it where I can put the wire lead onto the item that I am measuring? If not, how far away do you need to have the gauss meter from the magnetic field? Thank you for your time!

Asked by: Clay
Thank you for your inquiry. This unit is 'complete' with no lead wire accessories. The meter is held in the vicinity of the gauss field. For the best readings, you should get as close as you possible can to the field and record the highest value that the digital display is showing. We have no 'minimum distance' or 'maximum distance' spec for this product; if using in the manner described you will have good results in gauss measurement.
