Multi-Gas Detector Polytector III
- One for All!
- Innovative multi-gas detector monitors   up to 7 gases simultaneously


The Polytector III sets new standards in personnel safety. Its advanced concepts make it a truly superior confined space instrument. Whatever combination of gases you need to monitor, the Polytector III will reliably take over the measurement task. Through its interchangeable cartridges the change of the measurement task becomes simpler than ever.

Increased safety for confined spaces
Confined spaces can be safely monitored before entering by means of the built-in pump. If the pump is switched on (by sliding up the cartridge grill), the diffusion outlet automatically shuts down to avoid a distortion of the measurement results due to wind. Even today many gas detectors require a pump adapter or the whole pump to be mounted. This is not necessary with the Polytector III; just turn the pump on or off in no time - it's just that easy!
A loud acoustic alarm (99dB) and a 360º visible flashing alarm lights immediately indicate a gas hazard. For extremely noisy environments the Polytector III can also be equipped with an optional vibrating alarm.
Easy operation
Despite its groundbreaking features the Polytector III is very user-friendly and simple to operate: 3 buttons are all you need for operation of the detector. The pump is easily activated by sliding the grill upwards. This immediately shuts down the diffusion outlet without the need for further handling. The large display with huge readings allows for easy reading of the measurement values even in dimly lit conditions. By a single push of a button the display, affixed on top of the detector, can be turned by 180º to make sure that you can easily view the readings no matter which side you are looking at the detector.
Flexibility above all
The Polytector III is extremely flexible in its measurement tasks. Through its smart sensor technology the sensors can easily be replaced. The Polytector III recognizes the sensor type, measuring gas, detection range, calibration curve, as well as alarm threshold values.

Leak detection and advanced features...
The external leak sensor allows to easily detect even smallest leakages. Rising or falling sound frequencies indicate whether you get closer to a gas leak or not. When changing the sensors or replacing the battery pack, the detector is immediately operational again. The battery pack can be easily removed from the detector and connected to the charging unit which only needs 4 hours to recharge it; therefore, down times and maintenance times are minimized. The metal hydride battery pack shows no memory effect and ensures a long lifetime.
Robust design for harsh environments
The rugged and small housing detector weights only 600 grams (21 oz) and is dust and splash-water proof designed in protection class IP 64. It is designed for extremely tough operations under the most difficult conditions. An additional rubber boot assures that the Polytector III is extremely resistant against damages from falling.

Data Logger (optional)
The data logger saves low and high peak values, which can be displayed later by means of a serial digital interface on a PC.
Protection from hundreds of gases
Up to 6 gases can simultaneously be monitored - oxygen, combustible gases and vapors (in %LEL/Vol.%), up to 3 toxic gases plus you can equip it with the ToxAlert sensor. And all this with one single instrument. Due to the dual-tox sensor for CO and H2S, which continuously monitors both gases with one sensor and accurately displays the measurement values 7 gases are measured even though only 6 sensors are used.

Protection from the unknown
Electrochemical sensors are standard in virtually all portable confined space monitors because they can identify specific known gases. However, in many environments such as sewers or storage vessels, unknown gases may be present. For protection in these cases, a broad range sensor is essential. The groundbreaking broadband sensor ensures you additional superior protection from hundreds of unknown toxic gases. The combustible sensors in conventional gas monitors will detect most gases or vapors. In many instances, the gas or vapor is more toxic to human health before it reaches combustible levels. Some extremely dangerous gases are not combustible and would therefore never be detected.
Common gas detectors warn of 4 or 5 gases
