The low-pressure gauge in this series reads in inches of water column (in H2O) with a capsule element: an elastic capsule that resolves pressures too low for a standard Bourdon tube (1 in H2O = 0.0361 psi ≈ 2.49 mbar). It is a dry instrument for air, water and oils.

Before using these data in engineering decisions — design, installation or systems with mechanical risk of pressure, rupture, fatigue, impact or water hammer — you must read the Technical notice and limitation of liability at the end of this page.
The exact in H2O range is confirmed at quotation: the source data sheet does not publish it.
Dial pressure gauges, including low-pressure capsule types, are selected per ASME B40.100-2022 (Pressure Gauges and Gauge Attachments).
For process pressures in psi or bar, see the glycerin-filled gauge or the black case dry gauge.
It measures very low pressures expressed as the height of a water column: 1 in H2O equals 0.0361 psi ≈ 2.49 mbar. It is the typical unit for low-pressure gas networks, ventilation, burners and tightness tests.
Because at pressures of a few inches of water a Bourdon tube barely deflects: the elastic capsule of a capsule gauge provides the sensitivity that range demands.
The exact range is confirmed at quotation because the source data sheet does not publish it; the in-stock unit has a 2.5" dial with bottom (lower) 1/4" NPT connection and costs COP $180,000 + VAT.

The dimensions, thicknesses, pressures, temperatures and other characteristics stated in this data sheet are theoretical nominal reference values, compiled from publicly available technical sources: international standards (ASME, ASTM, API, MSS, ISO and NTC, depending on the product) and published engineering literature. They are average approximations intended to guide selection, not a certificate of conformity for any given lot.
Actual values may vary due to conditions inherent to the manufacturing process — dimensional and wall-thickness tolerances (in pipe, typically ±12.5%), surface finish and residual stresses from forming or welding — and to factors inherent to the raw material — chemical composition variations within the ranges allowed by the standard, inclusions or heat-to-heat differences. They may also be affected by in-service events not foreseeable at design time: water hammer, vibration, thermal and mechanical fatigue, corrosion and operating overpressures, which can cause the element to fail before its estimated service life.
To know the certified behavior of a specific lot, TECTUL supplies upon request the manufacturer's mill test certificate (MTC) issued per the product standard; for critical applications, laboratory testing of the lot can also be arranged. In the absence of such certification, the data provided here must not be used as the sole criterion in critical or safety applications, or wherever the integrity of the line may compromise the lives of people or property; in such cases, consult our technical team first.
