FirstCheck is the very first multigas to combine complete VOC and toxic gas detection from ppb up to 10,000 ppm with traditional multigas sensors for oxygen, hydrogen sulfide, carbon monoxide and explosive gas detection. Making FirstCheck a must have instrument for first responders and confined space entrants.

FirstChecks unique, highly sensitive photoionization detector (PID) enables the detection of many gases that are toxic at low ppb levels and are undetectable by traditional VOC detecting multigas instruments. Traditionally, two to three instruments are needed to ensure workers safety. Now FirstCheck has it all covered in one handheld detector.
