Chemteq Inc. products

Acids Area Monitor is highly sensitive and selective indicator for the presence of traces of acids in air. Suitable location positions for the area monitor are on stack, duct, vent or flue where representative samples can be obtained.

Aromatic diisocyanates area monitor is sensitive and selective for the detection of traces of aromatic diisocyanates. For best results, attach area monitor on stack, duct, vent, or flue. Reliable and cost effective means for monitoring air quality.

Aromatic Diisocyanates ChemWipe surface contamination testing (PN: 304) is a colorimetric surface wipe designed to provide real-time indication of the presence of trace of aromatic on surfaces. The ChemWipe is selective and sensitive. The unique design of the ChemWipe provides uniform color change formation enabling user to quantify chemical contamination using the color comparator.

Detects and quantifies aromatic diisocyanates on surfaces. Item No. 304-6000. Color Comparator: Length = 110.4mm (4.34”), Width = 103.5mm (4.0”), Height = 10.5mm (0.4”).

Chemteq DG Colorimetric Indicators are available for wide variety of  gases and vapors in air. They are suitable for OSHA TWA and STEL measurements. Even coat for reproducibility and accuracy. Real time and direct read. Detection limit at or below OSHA PEL. Accurate and reproducible (overall accuracy, better than ±25% at the 95% confidence level). Selective to target chemical. long service life and shelf life.

The Acids DG Filters with end-of-service life indicator (ESLI) is an efficient and reliable filter most suited for chemical processes and reactor vents. The ESLI allows user to safely use filter without the possibility of toxic gases and vapors breakthrough to the surrounding environment. The ESLI changes color when the filter is about 75% to 80% consumed, allowing 20 to 25% of sorption media as safety buffer.

Ammonia & Hydrogen Sulfide Filter ESLI – PN 7406. The Ammonia & Hydrogen Sulfide DG Filter with end of service life indicator (ESLI) is an efficient and reliable filter most suited for chemical processes and reactor vents. The ESLI allows the user to safely use filter without the possibility of toxic gases and vapors breakthrough to the surrounding environment. The ESLI changes color when the filter is about 75% to 80% consumed, allowing 20 to 25% of sorption media as safety buffer.

Acids Vapors DG-FILTER 721 is an efficient and reliable filter.  Most suited for chemical processes and reactor vents. Special blend sorbent media for maximum sorption of acid gases and vapors. Easy refilling of consumed sorption media. For best results, use with corresponding filter change indicators, BTI or BTI2.  Filter change indicator alters user in real time to replace filter. BTI and BTI2 are sold separate. Acid gases and vapors include acetic, hydrochloric, nitric and halogenated organic acids.

Filter for Chemical Processes and Reactors Vents. Item No. 764. Allyl Bromide DG-Filter 764. Dimensions: Length = 16”, diameter = 9.4”, Inlet & outlet = ¾” to 2.5” female NPT. Description: Up to 5 lb. of special blends sorption media. Easy refilling of consumed sorption media. Optional use of filter change indicators allyl bromide BTI (PN: 170) or allyl bromide BTI 2 (PN: 422) depending on the selected filter outlet. Sold separately.

Acid Vapors Filter Change Indicator. Colorimetric indicator that indicates the saturation and exhaustion of filters. It is reliable and cost effect means for protection from exposure to acid vapors. The indicator changes color from orange to red when filter is saturated with acid vapors. Connect the indicator to the ¾ inch female NPT outlet of filter using the ¾ inch male NPT threading at the bottom of the indicator. Indicator is sensitive to acid vapors. Observe bright vibrant color change from all directions. The unique design of the indicator prevents any color change due to exposure to contaminants in the surrounding environment. It changes color only when filter is saturated. PN 180.
