The ShakIR accessory provides a fast, simple and inexpensive method of mixing and grinding samples for diffuse reflectance sampling and in preparation for making KBr pellets. The ShakIR thoroughly mixes and pulverizes the sample within seconds. The accessory provides electronic control for precise and reproducible setting of ...
This unique high pressure, non-diffusive sample gas tubing is outfitted with special connection fittings. ...
The design of the fixed pump minimizes diffusion into the sample to prevent contamination by atmospheric oxygen. Less than 1ppm of oxygen can be expected to be added to the sample by the pump. The exact amount depends on sample flow rate and ...

The Acme Quadset Refrigerant Gas Monitor is designed to detect refrigerant leaks in enclosed areas. The Monitor utilizes a sophisticated NDIR sensor specific to any one of the commercially available refrigerants. It can monitor over a range of 0-1000ppm with a resolution threshold as low as 1ppm. The QuadSet can monitor up to four locations in one of two modes of operation, diffusion or ...
The Fusions Diode is a diode-laser based system for controlled heating of samples within micro-furnace packets to the point of fusion. The Fusions Diode enables the use of high capacity, multiple well, HV sample chambers and provides localized heating of samples in diffusion cells without the use of a furnace. ...
The use of passive or diffusive air sampling technology has gained in popularity over the last 25 years. ...

The AutoDiff is a high performance, automated diffuse reflectance accessory developed to analyze multiple samples with minimal user intervention. Typical applications include powdered pharmaceutical samples, high throughput forensic sampling, kidney stone analysis, soils and analysis of many other powdered samples where speed and efficiency are important. The design employs an automated R-theta ...
Flow Directors are designed to transform SenseAir K30 and K33 model sensors from diffusion to sample draw sensors. The tube cap kit attaches directly to the top of the sensor with self-tapping screws. ...
The CO2Meter Tube Cap Adapter accessory easily converts a wide range of gas sensors from diffusion applications to sampling. ...
Personal exposure testing has now become an issue amongst staff administering this gas on a regular basis. Diffusive sampling methods for both workplace and personal exposure monitoring have been developed using the thermal desorption diffusion tube. ...
All competitive sensors use a straight path of infrared energy shining through an air sample to measure CO2. The amount of gas that can be sampled, called the “path length” is limited by the size constraints of their wall-mounted and duct-mounted cases. ...
