Product Introduction

The CZM40 gas detector, a four in one gas detector for mining, is specifically designed for detecting entry into hazardous environments and enclosed spaces. It can simultaneously detect the following four gases: combustible gas, O2, CO, and H2S. M40 is durable and its casing is impact resistant and electromagnetic interference resistant, ensuring good performance even in harsh environments. Four function keys can be used for simple and intuitive operations, including browsing data, zero calibration, calibration, etc., with a 5-second shutdown delay

Brand Details

Industrial Scientific Corporation is a globally renowned professional company that designs, manufactures, and sells industrial grade portable toxic and harmful gas detectors. The headquarters of Industrial Scientific Corporation is located in the important industrial city of Pittsburgh in the United States. Its predecessor was the research and development department of the National Mining Services Corporation, which provided a large number of underground safety detection instruments for mining safety in the United States. In 1976, the R&D department was restructured into Industrial Scientific Corporation of the United States. In 1994, it became an ISO9001 certified enterprise for industrial manufacturing companies in the United States and a gas detection instrument supplier for NASA. In 2002, Industrial Scientific was recognized by authoritative institutions in the United States as a manufacturer of portable gas detectors for the American market.

In 2000, Industrial Scientific established a wholly-owned subsidiary, Industrial Scientific Sensing Instruments (Shanghai) Co., Ltd., in Jinqiao Industrial Development Zone, Pudong, Shanghai, China. This enabled Industrial Scientific products to enter the booming Chinese industrial safety equipment market more directly and quickly, providing more convenient customer service to Chinese customers.

Nowadays, Industrial Scientific has two manufacturing bases worldwide and sales service centers in 25 countries, committed to eliminating workplace fatalities in this century. And it has passed the certification of ISO 9001 quality management system, ISO 14001 environmental management system, and OHSAS18001 occupational health and safety management system. Become a leading enterprise in the gas detection industry.
