Axel Semrau® represents continuity and innovation in odorant analysis.

The ODOR handy ^plus is based on 30 years of experience with hand-held measuring instruments for odorant control in natural gas. It is equipped with an electro-chemical sensor alternatively for the measurement of the concentration of THT or of mercaptan in natural gas and combines proven sensor technology with state of the art device control.

Safe, fast and simple measurement of THT or mercaptans!

Sturdy metal housing, selective sensors, clear menu guidance with function keys, data memory, battery charging station, ATEX approval - the new ODOR handy plus captivates with state of the art technology and simple handling. The measuring gas is fed directly via a flexible hose to the ODOR handy plus. Depending on the odorant, the concentration of the odorant is displayed after just 1 to 2 minutes. The result can be read off directly in mg/m³. Other units of measurement can be set in the software. The measured data are stored with details of the measuring point, date and time as well as a note for odour perception and can be retrieved at any time. Apart from the measuring function, the ODOR handy ^plus can perform continuous monitoring of the indoor air, e.g. while working on odorising systems. Information such as memory capacity, serial number, date or time can be retrieved via the device software. Distinct and clear menu guidance ensures, for example, that equilibration times of the sensor are adhered to.
