PRESSURE VACUUM GAUGES
BOURDON TUBE TYPE
HEAVY DUTY STAINLESS STEEL CONSTRUCTION
The heavy gauge housing is intended for rugged outdoor use. ERL Pressure Gauges have all stainless steel cases and safety glass lens. The bottom 1/4" NPT attachment fitting is instrument-quality brass.
±0.5% ACCURACY
A large easy-to-read dial is calibrated to ±0.5% full scale accuracy. ERL can prepare a Certificate of Accuracy, should you require one, for a nominal fee. Re-certification, calibration and repair services are also available. For accuracy and proper operation, all Pressure Gauges must be mounted in the vertical position and the gasket under the vent cap must be removed to allow the gauge to breathe.
SILICON FILLED
The inside of the gauge is filled with pure silicon to dampen needle fluctuations and protect the precision internal mechanisms. Gauges can be provided dry upon request.
