TENMARS TM801 Carbon Monoxide Meter in Sri Lanka

Handheld CO Meter with Adjustable Alarm and Temperature Display

The TENMARS TM801 Carbon Monoxide Meter is a portable CO tester that measures carbon monoxide from 0 to 1000ppm. Carbon monoxide is a poisonous gas with no smell, colour or taste, and it reduces the blood's ability to carry oxygen. The TM801 helps technicians, safety officers and workshop operators in Sri Lanka check CO levels before they become a hazard.
