Chemcassette Monitors Rentals

Used for selectively montoring for one of over 45 toxic gases, chemcassette technology is not only free from interference with other compounds, but is also sensitive enough to detect many gases at very low concentrations. Our chemcassette monitor rentals are available in three different versions including a battery powered portable model, a highly durable monitor for outdoor use, and for monitoring multiple points simultaneously.

Honeywell SPM Flex

Gas Detector

Honeywell SPM Flex

The Honeywell SPM Flex is a portable, single-point gas detector designed to measure low concentrations of specific toxic gases using Chemcassette tape technology.

MDA Scientific TLD

Portable Chemcassette Gas Monitor

MDA Scientific TLD

A ChemKey rental offers all the advantages of Chemcassette technology in a portable battery powered instrument. ChemKey detectors monitor a single point and are able to selectively measure 1 of over 45 different toxic gases, often down to the ppb level, without interference. Chemcassettes require no calibration and provide physical evidence of the measurements. ChemKey rentals require the purchase of Chemcassettes for your application.
