TSI Instruments Ltd

TSI Instruments Ltd is a global leader in precision measurement instrumentation used where data quality and defensible results matter; from health and safety and industrial hygiene through to environmental monitoring and HVAC testing. With decades of specialist engineering behind the brand, TSI focuses on turning complex exposure and performance questions into repeatable measurements you can trust.

Aligning strongly with respiratory protection programmes and the practical job of proving fit and compliance with objective evidence. The broader TSI workflow mindset matters here; instruments, accessories, and software support are designed to reduce operator variability and produce audit-ready outputs.

TSI fits when your pain is risk you cannot see, inconsistent testing, or the cost of getting compliance wrong. If you need a measurement you can stand behind, plus a brand that is widely specified in professional air and exposure monitoring, TSI is a sensible shortlist choice for organisations that take worker protection seriously.
