Pre-purchase and technical reference for IAS nuclear air purification products. Answers to the most common questions from procurement engineers, facility managers, and project teams worldwide.
One page per decision: the eight IAS-T tritium monitors side by side — type, measuring range and typical duty — plus the model combinations our engineers most often specify for fusion, heavy-water, light-water and DOE laboratory facilities.

Every model in the guide has a full specification page in our tritium monitors hub.
| Model | Type | Range |
|---|---|---|
| IAS-TP20 | Portable survey monitor | 1 µCi/m³ to 1 Ci/m³ |
| IAS-TA20 | Fixed area monitor (19-inch rack) | 1 µCi/m³ to 10 Ci/m³ |
| IAS-TA30 | Fixed area monitor (floor-standing cabinet) | 1 µCi/m³ to 10 Ci/m³ |
| IAS-TG30 | Glovebox & process monitor (sealed, all-metal) | 1 µCi/m³ to 10 Ci/m³ |
| IAS-TG10 | Process detector (wall-mount, PLC-ready) | 1 µCi/m³ to 10 Ci/m³ |
| IAS-TD20 | OEM ion chamber detector module | 1 µCi/m³ to 1 Ci/m³ |
| IAS-TS40 | HT / HTO speciation monitoring system | 1 µCi/m³ to 10 Ci/m³ |
| IAS-TW10 | Surface contamination (wipe) monitor | 0–1 Ci/dm² wipes, < 2 min |
Fusion (D–T): TA20 for rooms, TG30/TG10 for gloveboxes and the fuel cycle, TS40 on exhaust, TP20 + TW10 for surveys. See our fusion tritium monitoring overview.
Heavy-water reactor: TA20 area monitors, TS40 on ventilation, TP20 for surveys.
Light-water reactor: TP20 surveys with TA20 at fixed points.
DOE / national laboratory: TG30 gloveboxes, TA20/TA30 rooms, TS40 stacks, TW10 surfaces.
Not sure which form factor fits your sampling point? Our guide to choosing a tritium monitor walks through the decision, and the DAC unit converter helps translate between µCi/m³, Bq/m³ and DAC.
