Specialists in Humidity, Moisture Measurement, and gas analysis systems.

Over the last 20 years IMA have become known as experts in hygrometry, moisture, watercut, water in oil, oil in water, hydrogen sulphide, and process gas analysis systems.

They supply hygrometers, trace dewpoint meters, relative humidity analysers, and moisture in solids analysers to a wide range of industries including oil and gas, nuclear, and manufacturing.

For the oil industry IMA offer the Delta-C watercut analyser (water in oil analyser, or WIO analyser). For produced water discharge there is an UV fluorescence oil in water analyser. These are typically used in PPM oil in water discharge.

Since the advent of tunable diode laser (TDL) analysers, IMA have a strong range of carbon dioxide (CO2) and hydrogen sulphide (H2S) measurement systems. In fact a wide range of species can be measured: carbon monoxide (CO), ammonia (NH3), nitric acid (NO), hydrochloric acid (HCl), ethylene oxide (ETO), hydrofluoric acid (HF), methane (CH4), oxygen (O2) and many more.

IMA can also offer maintenance contracts, measurement audits, calibration, commissioning and efficiency studies.

Process Gas Analyser

The process gas analysers offered by IMA use a variety of techniques including tunable diode laser (TDL) technology to provide fast and accurate analysis in a wide range of applications.  These analysers can be supported by bespoke sampling systems.

Moisture Measurement Meter

IMA are experts in moisture measurement  in a wide range of situations.  Water in oil systems, Dewpoint meters... Moisture in solids can be measured using the range of... Water in oil is covered by the...

Relative Humidity - RH

Relative humidity meters available from IMA are the latest generation of humidity transmitters based on digital technology, which significantly enhances humidity measurement. The HygroFlex sensors, using the interchangeable Hygroclip probe, are extremely flexible.

The Hygropalm is a hand-held version of these humidity instruments, offering all the features of the on-line analyser, in a portable form.

Displays and Loggers

The Breeze series of digital panel meters for remote display of key industrial measurements is a complete range, from economical simple OEM models, to remote controlled IP65 wall mounting units. Options with integral power supplies are ideal for driving loop powered transmitters. Inputs include current, voltage, PT100 or Modbus. Measurement ranges and alarm setpoints are user programmable via modbus, or an optional remote control. Variable delays for relay activation and de-activation, and a peak hold facility are available on some models. Analogue outputs and alarm relays allow for transmission or re-transmission of data to a DCS or SCADA system.

A comparison of the different models available, and individual product descriptions, can be found at the IMA web site.

Dewpoint meter calibration

IMA can provide an accurate and independent dewpoint meter calibration service for most makes of trace moisture analysers.

The service is high quality, competitive, and fast, with a usual 1 - 2 week in-house turn around on most probes.

Our calibration rig employs state of the art chilled mirror systems, traceable to National Standards, in a modern purpose built calibration room. The quality of the equipment and IMA's knowledge of moisture ensures the accuracy and validity of the service.
