Dwyer Digital Guage

Dwyer Digital Pressure Gauge

The ultimate in Digital gauges is now here! Dwyer has produced one of the finest digital gauges and the best part it is only $219.99. The gauge can be set in both PSI and bar with just a push of a button. The unit is also enclosed in an aluminum case with o-ring sealed polycarbonate ends. The Digital gauge is used in mixing due to its degree of accuracy and the ability to read each individual PSI.

Digital Gauge Reasoning: Digital gauges are really necessary to do proper mixing of nitrox and trimix gases. The Gauges allow within a psi accuracy across the full range. If you mix with an analog gauge your accuracy rate falls to about 10 psi prior to filling and 10 psi after filling. This might not seem like a big deal until you analyze your mix. If you started with a nitrox or trimix mix half full and are topping off what happens is that you can be off by a large percent due to the inaccuracy of the gauge. With the price of digital gauges down to such a reasonable price of $299.99 it does not make sense not to go this route.
