Trace gas sensor TS 810 SDI

Effective trace gas detector for leak detection or tightness tests

Professional trace gas detector "made in Germany"

The unique characteristics of hydrogen introduce manifold advantages when used as trace gas for leak detection or tightness tests to the user. The hydrogen sensor TS 810 SDI unites these benefits in an economical way with the high flexibility of the T3000 multifunction measuring meter.

The result: A quality product "made in Germany" during the development of which high-precision sensor technology and a sensational value-for-money ratio could be combined despite complex manufacturing processes.

Make your own comparisons: The acquisition of adequate competitive solutions is five to ten times more expensive!

Effective measurement method

The sensor TS 810 SDI captures hydrogen, which e.g. in the usual 95/5 % forming gas is used as tracer gas for leakages, and thus in an easy way enables users to perform a non-destructive location of the highest concentration of hydrogen within the measuring area, e.g. for the location of cracks and leaks in pressure tanks, pipes, tanks etc.

The size of the test object is irrelevant, for due to its high resolution accuracy and the measuring range from 0 to 1,000 ppm of H₂, the sensor system also captures minor concentrations of hydrogen from about 1 ppm H₂. To ensure an optimum adjustment to different operating conditions the sensor can naturally also be set to a lower sensitivity level.

The sensor element of the TS 810 SDI is protected by a high-quality stainless steel sinter filter.

Acoustic and numerical indication of measured values

During measurement, rising and falling hydrogen concentrations are indicated acoustically at the sensor housing as well as by the numeric display of an indicative measured value on the display of the T3000. This way, with respect to the highest H₂ concentration the user can be guided optionally by the signal tone interval or the displayed measured value and so systematically narrow down the position of the leak to be detected.

Compact solution for wireless mobile application

The energy supply of the trace gas sensor TS 810 SDI is effected entirely via the T3000 multifunction measuring meter, hence there is no need to carry along any additional rechargeable battery cells for sensor operation. These savings in terms of weight and space become particularly noticeable during longer measuring operations. Owing to the bendable gooseneck, measurement results can also be determined in locations which are only poorly or inaccessible when using a rigid measuring head.

The sensor sensitivity can conveniently be adjusted in five steps directly at the hand-held housing. Moreover, the acoustic indicator can also quickly be switched on or off as needed. Furthermore, the zero reset can be carried out at the push of a button – a special function for the differentiated indication measurement by means of two real-time measured values based on different position coordinates.

The zero reset function even allows the subsequent measuring of an increased concentration in ambient air already highly enriched with tracer gas. In combination with the very high sensitivity, even the smallest leakages can be located with pinpoint accuracy by means of a multiple zero reset. All the selected settings are displayed by means of an LED bar graph integrated in the housing of the TS 810 SDI.

Enables more economical test processes in the industry

The TS 810 SDI sensor creates the conditions for faster test processes, since the hydrogen measurement method is an effective alternative to conventional methods for tightness tests or leak detection.

These are either relatively labour-intensive and time-consuming, such as e.g. the bubble test after soaping workpieces or the pressure drop test, or else require a considerable complexity of equipment needed, as is the case with the helium tightness test.

With the combination of TS 810 SDI trace gas sensor and T3000, production plants are provided with the ideal measuring equipment for tightness tests of weld seams, pressure tanks or pressure lines.

Checking pump bodies for leakages can easily and very economically be realized with the hydrogen leak detection and the T3000.

Telescopic rod and sensor holder TS 810 SDI

Accessory tip:

For measurements at distant or poorly accessible locations, a telescopic rod adjustable in length and with variably inclinable head plus a matching sensor holder for the TS 810 SDI are optionally available.
