Introducing CheckMate, a new geophone tester.
This evolutionary new geophone tester is everything that it should be. A light,
hand portable, thoughtful solution to accurate geophone instrument testing.
|
|
 |
Features such as a keypad that can be used without removing your gloves in
cold conditions, data transfer and battery charge via USB cable, backlit
display and four user definable macro keys that can be used to set up
various test functions or key sequences.
At a quarter of the weight, and less than half the size of our competitors,
we have also added Nema-4 environmental packaging for water/icing/salt
superiority. Whether you are testing on the line or in staging, you’ll
appreciate CheckMate ultra-portability and usability.
And, CheckMate also meets or exceeds the testing capabilities of every other
geophone tester on the market.
