Product Description

The Series 150 Portable H2S Analyzer Monitor is a completely portable gas analyzer. The analyzer features a cost-effective continuous analysis method for process control, air quality, laboratory, atmospheric monitoring and product quality purposes. In addition, the gas analyzer is accurate, dependable, and low maintenance. Maximum versatility is offered with its compact (10″ x 12″ x 6″), lightweight (10 lbs), and wide range ability (single digit ppb to 500 ppm). The analyzer includes a rechargeable battery pack for completely portable operation in the field. An optional internal sample pump is available if sampling of the atmospheric air or similar is required. An optional Data Logger allows for data download to memory module for upload to PC for review.

The analyzer features the only detection technology capable of measuring hydrogen sulfide without interference or “false positives” from other components. The microprocessor-based technology provides analysis based on the specific and interference free ASTM approved tape detection of operation. As the sample enters the analyzer an on-board precision flow meter regulates flow rate. The sample is then humidified by the Humidifier Chamber. Next, the sample is introduced to the specific lead acetate sensing tape. Hydrogen sulfide is the only component that will form a brown stain on the tape which is proportional to the hydrogen sulfide concentration (rate-of-change based).

The advanced photodiode detector and LED light source in optics system measures the rate of darkening of the stain which creates an output signal. This signal is digitized and analyzed by the advanced 24-Bit A/D microprocessor converter and related software resulting in a linear 4-20 mA output. The LCD display provides the current reading, any alarm condition, procedure prompts (i.e. calibration), and failure indicators. The analyzer measures the hydrogen sulfide content continuously.

This reliable field proven gas analyzer system continuously and specifically quantifies the hydrogen sulfide level in the sample with very minimal maintenance. Users demand KECO’s portable H2S analyzer due to its precision, simplicity and reliability proven by thousands of worldwide installations around the globe.
