manufacturers, supplies, repairs, calibrates and certifies all types of fine
quality Pressure, Vacuum, Compound, Tank Contents and Test Gauges, and
Temperature Gauges, including Digitals, to suit all purposes. We test and
certify safety valves, pressure vessels and hoses.
Gauges
Heavy Duty
Robust pressure Gauge which is
best suited to working in more arduous conditions, whilst giving a reliable and
sustained working life. This gauge can be used on air, water, oil or any
substance that will not attack copper alloy parts.
Standard, Class 1.6
General purpose pressure gauge.
Suitable for all gaseous and liquid media that will not obstruct the pressure
system or attack the copper alloy parts.
Standard, Class 1
General purpose pressure gauge.
Suitable for the Heating and Ventilating Industry, and can be used on air,
water, oil or any substance that will not attack brass.
Stainless Steel
Weatherproof, robust instrument
especially designed for the petro-chemical and food industries. The Stainless
steel construction affords great advantage in a hygienic or even an aggressive
atmosphere and on high temperature processes.
Liquid Filled
These Gauges are mostly used in
the hydraulics industry due to their waterproof and robust construction with the
added advantage of being able to cope with the pulsation and mechanical
vibration thus sustaining a long service life.
Capsule
Capsule gauges are designed
specifically for use on low pressure gases which cannot be measured with a
bourbon tube gauge. It should be noted that these sensitive gauges should not be
used on liquids.
| Diaphragm
These Diaphragm gauge is
particularly useful for the pumping and transporting of viscous liquids
and powders. The use of a diaphragm avoids any clogging that would occur
in a bourdon tube gauge and on some chemical processes unsuitable for
bourdon gauges.
Safety Pattern
Where the pressure medium
is a volatile gas, such as oxygen or acetylene, a safety pattern gauge
should be used, where the gaseous medium is not volatile, such as air or
nitrogen, and the pressure is greater than 25 bar the Fig. 90 gauge
(safety pattern) should be used. The essence of this type of gauge is
safety
Test
These hand crafted
instruments are guaranteed to have an accuracy not exceeding ± 0.25% of
Maximum Scale Value. The careful selection of quality parts ensures this,
and every Test Gauge is supplied with a point-by-point calibration
certificate with traceability, through our test equipment, to National
Standards. |

Diaphragm Seal and Hygienic
Diaphragm seal gauges are
designed to avoid any clogging that would occur in a bourdon tube gauge and can
cope with a greater range of process temperature and aggressive product. They
can be manufactured with special materials not available in bourdon tube gauges
and with a remote reading facility. The diaphragm seal gauge is particularly
suited to the petro-chemical and Food industry.
