Temperature

Temperature calibration needs to be routinely carried out in a number of applications for either auditing requirements or quality control. These include –

•  Pasteurizers
• Reactors
• Critical process points
• Timber drying kilns
• Chillers and freezers

Our test gear is checked annually at an IANZ Accredited Calibration laboratory and

include a stirred Water Bath, Hot Block and portable digital indicators.

Pressure

A range of digital pressure gauges and hand pumps enable calibration checks from 1 mbar absolute to 200 bar gauge pressure. Calibration checks carried out include –

• Critical plant pressure indications
• Static head level measurement
• Pressure switch interlocks
• Pressure gauges

Flow

We have two flow rigs which are battery powered and completely portable.

A micromotion CMF Elite 0.5 inch mass flow meter which is very accurate at flow

rates of 20 kg/hour to 6000 kg/hour

A 40mm mag flow for flow rates of 5000 to 20000 litres /hour

These rigs can be piped up in series with critical plant flow meters in place, and either

rates or flow totals verified. In applications like –

• Batching additive flow meters
• Plant inlet and outlet totalizers
• Product blending
• Fillers

Weight

The portable mass flow rig is also used to check calibration of weigh tanks and hoppers.

Analytical

Calibration and maintenance is carried out on a wide range of analytic instrumentation

including –

• PH meters
• Conductivity
• Turbidity
• Flue gas analysers (Oxygen, SO2, CO, CO2)
