BetaGauge 330 has absolute pressure ranges

In June, we started shipping the BetaGauge 330 with available absolute pressure internal sensors. The 330 is now available with a 30 PSIA (2 barA) or a 150 PSIA (10 barA) internal sensor. Coupled with the 330’s built-in electric pump, this allows calibration down to about 20% of barometric pressure. If needed an external high… Read more »

Is It a Calibrator?

We (people actually in the calibration industry) often hear things being called calibrators that obviously aren’t. A great example is the Emerson HART(tm) communicator. No offense intended, but these types of devices aren’t calibrators, they are electronic “screwdrivers” that enable a technician or engineer to adjust the calibration of a device. Here are my defining… Read more »

Martel Updates BetaGauge Calibrators

We have updated the very popular and powerful BetaGauge 311 and BetaGauge 321 Advanced Pressure Calibrators. The new models are the single range BetaGauge 311A and dual range BetaGauge 321A. What we didn’t change are the great performance and ease of use we already had. Here are the new features: Super rugged “Power-Tool-Tough” housing. We’re… Read more »

Reference Class – The Best of Both Worlds

Some of our competitors like to brag that by offering a percent of reading accuracy specification, they give better down scale performance than our percent of full scale specification. The problem is, that’s really not true. For the case in point, we’re talking about digital test gauges. Their very nice gauge has a specification of… Read more »

History of the BetaGauge – Part I

Since Martel is introducing a new BetaGauge at the ISA Show in Houston (October 14-16), I thought it would be a good idea to give you a short history of the BetaGauge calibrator line. (Note, this blog was first posted on Friday, September 12th, but due to a technical glitch, it was lost). The immediate… Read more »
