Exactus Labs builds calculators and assessment tools for occupational health and hygiene professionals. Twenty tools are currently live across physical agents, chemical agents, biological agents, and exposure analytics.

Every tool is built against a stated regulatory or consensus standard and shows its working. The goal is straightforward: reduce the time practitioners spend rebuilding the same spreadsheets, and reduce the quiet errors that accumulate when those spreadsheets are copied between jobs.

How the tools are built

• Each calculator states the standards it implements and the formulas it uses.
• Where standards disagree (for example OSHA versus NIOSH exchange rates), the tool reports both rather than choosing silently.
• Outputs include the validity limits of the calculation, not just a number.
• Results can be exported for inclusion in reports.

Access and pricing

All tools are currently free to use. Registration with a valid email address is required. A freemium model is planned — a core set of tools will remain free, with additional tools and features available on paid plans. Pricing details will be announced before any changes take effect.

What this is not

These tools do not replace professional judgement, formal dosimetry, accredited laboratory analysis, or jurisdiction-specific legal advice. They are calculation aids. Validate outputs against your measurements and your regulator before relying on them.
