UNIT's intrinsically safe products help to ensure workplace safety.
Our new product line is specifically designed for use in highly sensitive environments known as potentially explosive atmospheres.These environments can be found in various manufacturing settings, such as chemical processing, oil refineries, or any location where flammable materials like gases or dust particles are present. UNl-T's intrinsically safe test tools are designed to assist you in performing installation and maintenance within these potentially explosive and hazardous classified zones. It is crucial to understand the significance of intrinsic safety in your work and familiarize yourself with industries that commonly rely onintrinsicallysafetools.
At UNl-T,we pride ourselves on offering the most extensive selection of reliable, accurate,and intrinsically safe test toolsavailable on themarket.Our product rangeincludestrue-rmsmultimeters,true-rmsclampmeters,infrared thermometers,micro-ohmmeters,andthermal imagers.

Applicable environments are as follows:
1.Most of China's existing explosion-proof standards are technically in line with or equivalent to the rigorous IECand EN standards.
2. The UT195Ex/UT219Ex+ models are specifically engineered to safely manage various explosive gases commonly encountered in chemical plants,with the table offeringa selection of illustrativeexamples.
3. "Zone 2 or Zone 2 2 " accounts for 70 % ~ 8 0 % of"Explosive Atmosphere" generally.

| Zone 0 | High Risk | Zones where flammable gas mixturesare present continuously or for extended periods. |
| Zone 1 | MediumRisk | Zoneswhere flammable gasmixturesmay be present during normal operation. |
| Zone 2 | Low Risk | Zones where flammable gas mixtures are unlikely to be present undernormal conditions,or if present,only fora brief time. |
