Tracer – Leak detection in the ppb range Application The Tracer has its strength where other methods of leak detection would fail, because they have cross sensitivities to other gases. Such selectivity is requested in plants using or producing extremely toxic substances. These plants always have a „Zero Emission Policy“ in force. Here high sensitivity in combination with good selectivity is required. Sensor technology Electrochemical sensors can be designed to be very selective and sensitive at the same time by the right material choice for electrodes and electrolyte. These sensors will not respond to less dangerous substances that might be around in the plant such as hydrocarbons, carbon monoxide, hydrogen or even humidity. A detection limit of Phosgene as low as 2 ppb is no problem for this sensor technology! The Tracer is capable to detect even the smallest traces of toxic gases. The detection limit is in the low ppb range depending on the substance to be detected. As a leak detector might be exposed to very high concentrations, it must not be used as a personal monitor. To avoid it being abused as such, it displays no concentration, but only a dimensionless figure or a bar graph. Using the Tracer To locate a leak, move the sample intake along the surface to be inspected. The measured value will increase when a leak is approached. The display can be selected between bar graph and digital. A control tone and LED will increase in frequency with increasing measured value similar to a Geiger counter. The Tracer will protect itself from poisoning. If the measured value goes out of range the pump will go off and start again when it drops below 95% of the range. The graphic display is easy to read. At night or in dark places in the plant a backlight can be switched on. Consumables such as sensor, filter or sampling probe can easily be replaced without tools. Field test results – the high range version The first tests in plants have proven that an ultra-low measuring range does not always do the job. Therefore Compur Monitors has completed the Tracer product range by a new HIGH range version. It uses an orifice in front of the sensor increasing the measuring range by a factor of 20. The user can do that without changing the amplifier adjustment. All it takes is just replacing the LOW range sensor by a HIGH range sensor and so cover a measuring range from the low ppb range up to the two digit ppm level! The Tracer comes with 4 AA size disposable batteries. This version is not explosion proof. Ex Version Upon request the tracer can be delivered in an explosion - proof version with rechargeable batteries.

In the ink jet segment the EBS 1500 is known for it's simple but efficient handling. The printer can get equipped with a bunch of different printheads, optional from 16 nozzles up to 128 nozzles. Expressed in font height this means from 6 mm up to 230 mm. With our EBS-1500 you can operate up to 6 printheads with one controller. This is a big advantage for companies with several parallel production lines. It is possible to print a different project with each head. It's even able to work with pigmented inks. This brings you the maximum contrast for difficult materials. The EBS 1500 combines word processing with graphics, barcodes and data matrix codes in an easy-to-use graphical user interface. With features such as IP54 protection and the ability to connect up to 6 print heads to one controller, this coder is the right tool for large production lines and harsh conditions.
