De Wit 91(V) series

St.steel bourdon tube pressure gauges for measuring air, water, oil and aggressive media that are not highly viscous or crystallising and that do not harm 316 SS. Ideal for corrosive environments, (petro)chemical industry, on- and offshore, environmental technology etc.

Suitable for pressures between 0-0,6 bar and 0-1600 bar
Higher ranges available with CrMo52/NiSpanC bourdon tubes
V = liquid filled execution, for applications with pressure pulsations/vibrations or for
outside mounting

De Wit 91SF(V) series 

Full safety pattern st.steel bourdon tube pressure gauges for measuring air, water, oil and aggressive media that are not highly viscous or crystallising and that do not harm 316 SS. Ideal for corrosive environments, (petro)chemical industry, on- and offshore, environmental technology etc. where increased safety is required. Full safety pattern with solid baffle wall between movement & dial and full blow out back (EN837-1, safety class S3).

Suitable for pressures between 0-0,6 bar and 0-1600 bar
Higher ranges available with CrMo52/NiSpanC bourdon tubes
V = liquid filled execution, for applications with pressure pulsations/vibrations or for
outside mounting

More Information

De Wit 4501R(S) series 

Bourdon tube test gauge for applications where high accuracy of cl. 0,25 is required. For example for calibration of pressure gauges or pressure transmitters, in process control.

Suitable for pressures between 0-0,6 bar and 0-1600 bar.
V = liquid filled execution, for applications with pressure pulsations/vibrations or for
outside mounting

More Information

De Wit 181R(RV) series 

Bourdon tube precision gauges for exact pressure measuring of air, water, oil or other media where higher accuracy of cl. 0,6 is required.
Optional 316 SS wetted parts (De Wit model 181RR) for applications with aggressive media that do not obstruct the measuring system and are compatible with 316 SS.

Suitable for pressures between 0-0,6 bar and 0-2000 bar.
V = liquid filled execution, for applications with pressure pulsations/vibrations or for
outside mounting

De Wit Thermometer 5000 series 

DE WIT gas actuated thermometers are high-quality, stainless steel instruments suitable for various temperature applications.
They resist corrosion, chemicals, and harsh industrial conditions.
Using a gas-actuated, non-toxic system (no mercury), they ensure safe operation.

Available in rigid stem or capillary models for remote reading.
Commonly used in petrochemical, food, offshore, engine, paper, and process industries.

More Information

DeWit 4501R(S) series 

De Wit dead weight testers measure pressure by balancing known weights against the force on a piston of known area.

They include a built-in pump for calibrating gauges, transmitters, and recorders, and for high-accuracy pressure testing.

Accuracy is traceable to National Standards and verified by the Dutch Metrology Institute
(NMi VSL).

Each unit comes with a calibration report and manual.
Standard models use brass weights, with stainless steel and alternative unit options available on request.
