Measuring Moisture in Industrial & Analysis Gases

Using the latest addition to the Witt family,”Hydrobaby”

Witten, Germany –?? Moisture in gases and compressed air can cause considerable damage, so it is vitally important to perform regular checks. The latest device for this purpose is called “Hydrobaby” and is available from Witt.

The hand-held analyser has been developed for mobile use.

It features a ceramic metal oxide sensor that determines the humidity of the gas from the dewpoint.

This is generally recognised as a superior method:

  • very quick and precise measurements,
  • significantly lower sensitivity to environmental temperature,
  • very small measurement error(??2??C) and
  • large measurement range of -110 to +20 ??C.

These add up to real advantages over alternative sensor systems.

“Hydrobaby” is even suitable for sensitive applications such as medicine, pharmaceuticals and biotechnology.

Classic applications are industrial process monitoring, environmental technology, gaseous fuels and many other applications for technical gases and air, such as in the metals industry or food industries.

The handy device made of shock-resistant plastic and pressed aluminium weighs only 1.6 Kg (approx.).

It has an integrated long-life rechargeable battery and a backlit graphic display with multilingual menu.

It displays the relevant parameters such as dew point, relative humidity in percent and moisture concentration in ppm (parts per million), as well as the ambient temperature, pressure in the measuring chamber and a trend plot of the measured values.

For the latter a circulating memory that can store the last 4000 measurements is included.

An inbuilt test routine protects against measuring errors and warns if the filter is blocked.

Users can assign measurements to various products or processes by name.

The integrated USB port allows data export for further processing and documentation, as well as recharging the battery.

A separate model of “Hydrobaby” with ATEX approval is available for use in potentially explosive atmospheres and features various options for special applications.

About WITT

WITT-GASETECHNIK is a modern medium sized company which was founded by Paul Witt in 1945. The name WITT and later the WITT flashback arrestors with cut-off valves became synonymous with safety in the gas welding industry and spurred the steady growth of the Company. In 1969 WITT began to manufacture gas mixers for the production of shielding gases for welding and furnace atmospheres. This was the start of a second product range which now includes portable mixing, metering and analysing units, electronic control and readout systems up to complex processing equipment. WITT-GASETECHNIK exports far more than 50% of production. Their subsidiaries and agents are synonymous with customer satisfaction in more than 60 countries around the world. All products undergo a 100% check to guarantee safety and quality using sophisticated testing facilities and state of the art technologies.
