What does fully temperature compensated mean?

All digital pressure gauges are "temperature compensated" but when you study the fine print, you will find that temperature can still have a big effect on accuracy. Our products are fully temperature compensated, calibrated in an environmental test chamber, so the accuracy is the same over the entire operating temperature range, and they can be used to measure vacuum. All Crystal products come with a factory calibration report that proves it meets specifications at 5 different temperatures.
