Standard Caisson Pressure Gauge 160mm




Call for Price

The CDS  160mm diameter Standard Caisson Gauge  for mounting inside Hyperbaric Chambers, Caissons, Living Chambers & Decompresion Chambers is used for measuring simulated depth (pressure) within the chamber. The gauge is designed to be surface mounted within the chamber and features an internal sealed reference chamber set to atmospheric pressure by means of a manually adjustable balance valve located at the bottom of the gauge. Please note this gauge is calibrated to sea water with a specific gravity of 1.025 unless sprecifed otherwise.

In its standard design, the measuring element of this instrument is manufactured with a 1/4" BSP female connection that is  sealed off forming part of the internal reference chamber and balance valve arrangement. Optionally the gauge can be manufactured with a 1/4" BSP male connection if you intend the gauge to be connected/vented to atmpspheric pressure outside the chamber.  

This instrument is designed to be zeroed by opening the balance valve when the hyperbaric chamber is  vented to atmosphere, we recomend this is carried out every time the chamber is used to ensure accuracy of reading. To check the calibration of this  gauge, please note the instrument can only be  tested inside a pressure chamber.  If bench calibration is required on site, we recomend our Premium Caisson Gauge  as this design  can be calibrated in a similar fashion to a normal pressure gauge.

The gauge is supplied from new  with a Point to Point Calibration Certificate fully traceable to National Standards.
