The ChemKey™ TLD Toxic Gas Monitor provides a reliable solution for both emergency response and fixed area gas detection in a cost effective manner.
Utilizing the exclusive ChemKey™ Gas Selection System, a single monitor is capable of monitoring over 50 different gases with just a change of ChemKey™ and Chemcassette®.
As with all Chemcassette® based products, you are assured of fast, sensitive and substance specific exposure protection. There is never any danger of false alarms or inaccurate results caused by other commonly present chemicals.
Advantages
- Portable, flexible and interference free toxic gas detection
- Battery operated or line powered
- Exclusive Chemcassette detection is gas specific, sensitivity to ppb levels with physical evidence
- Low maintenance and no dynamic gas calibration
- Variety of signals outputs to meet monitoring needs
- Over 50 gases available, ChemKey allows switching target gases easily
Applications

What is a Chemcassette™?
Chemcassette™ is the unique trademarked name for a calibration free toxic gas detection method that uses an optical scanning system to detect the presence of gas by a color change on the specially chemically impregnated paper tape. Chemcassette™ technology is highly specific and reacts extremely fast to the presence of parts per billion (ppb) levels of many hazardous gases. Over 200,000 points of gas detection gas currently maintained by the Chemcassette™ sensing technology at any given time around the world in some of the most critical safety applications possible.
What support do I get when I buy a unique Chemcassette™ product?
Each Chemcassette™ is manufactured to traceable ISO 9000 manufacturing standards by a world class team of highly trained chemists and each batch is calibrated with ultra pure gas that is traceable to nationally accepted standards. This means that the end user does not have to provide calibration facilities themselves thereby saving cost and reducing risks to their own staff. Efficient high volume manufacturing techniques means that there is always available Chemcassette™ in stock that can be shipped anywhere so that each customer is never left without adequate safety cover.
What statistics prove the benefits of Chemcassette™ technology?
Honeywell Analytics has been manufacturing their Chemcassette™ sensor tapes for over 25 years and maintain traceable records on every production batch, every calibration and every instrument and calibration gas cylinder used to perform the calibration. Experienced scientists maintain a constant measurement environment when performing the calibrations and they are skilled at handling the very toxic gases used for testing and have double checks in place to confirm that the test gas is still within acceptable specification.
