A Truly Cost Effective Gaussmeter
The GM-200A gives you:

High Performance
The GM-200A is the highest performing gaussmeter in its class.
Effortlessly measure the fields from permanent magnets and from DC electro-magnetics from 0 to 10,000 Gauss with 2% accuracy and resolution of less than 1 Gauss.
With a single button click you can: take a single measurement, measure continuously for surveys, or have the GM-200A find and save peak values for you.
Handheld and lightweight, it weighs only 4.4 ounces. Single handed operation is easy, as the sensor is integrated with the case and there is no fussing with cables and connectors.
The GM-200A operates from 2 standard AA batteries. Power consumption is so incredibly low, that a single set of batteries will last you years.
Built to last, the GM-200A will give you years of trouble-free service.
Every GM-200A is individually factory calibrated using a NIST traceable gaussmeter. If you need a calibration certificate, they are available at only a small additional cost.
Advanced New Design
The GM-200A gaussmeter gives you the benefits of design excellence and experience learned at two of the most prestigious engineering companies in the world: Hewlett Packard and Agilent Technologies.
The GM-200A provides you with the optimum blend of performance, effortless operation, and pricing through the use of the newest design and simulation tools, plus extensive prototype development, testing and refinement.
With the GM-200A you get a brand new gaussmeter design utilizing the latest and best technologies. With a 16 bit microprocessor at its heart, a 16 bit sigma-delta ADC, and a very stable analog front-end coupled to a Hall effect sensor, the GM-200A combines simple elegant design and high performance together into a single device.
And, the GM-200A delivers it all in a small handheld package with simple one touch operation.
Effortless Operation
Using the GM-200A is effortless. With one button operation, just point, click, and read.
The reading is held on screen for 10 seconds and then the GM-200A powers down, automatically.
Magnetic field surveys are easy. As long as the single button is held down, the GM-200A will continuously show the field strength.
Want to know the peak value you saw during a field survey? It's done for you automatically. While the button is held down, the GM-200A saves all values it measured for the last 10 seconds. When you release the button, the peak value is shown. Easy.
Battery power is checked every time you push the button to make a measurement.
And what about zeroing the meter? Forget about it. The GM-200A doesn't need zeroing. The advanced new design does not drift. Simple.
There is no other gaussmeter on the market that makes measuring magnetic fields so easy and convenient.
Unmatched Price/Performance
The GM-200A Gaussmeter has the optimum blend of pricing, portability, performance, and effortless operation.
It's handheld, costs under $350, and yet each unit is individually calibrated in the factory with traceable accuracy to NIST.
Gaussmeters with equivalent performance, quality, and design pedigree often sell for greater than $500. With the newest design, and advanced manufacturing techniques you get a gaussmeter for much less.
You can now deploy multiple gaussmeters in your organization, rather than having to share a single high cost instrument. The outstanding price of the GM200A makes it easy.
Purchase your GM-200A, and get results quickly, easily, reliably, accurately, and confidently...at an un-beatable price.
