The cartridge looks like a Solo ES3 cartridge, is this the same cartridge?
No. Despite their physical similarities XTR2 uses a unique smoke cartridge. The new TES3 cartridge features a larger test capacity providing 800 bursts of smoke and can be purchased in packs of 3 from Detectortesters or your local authorised retailer (Part No. TES3-3PACK-001, TES3-6PACK-001)
Can you use the Solo ES3 cartridge in this tester?
Yes. Solo ES3 smoke cartridges can be used in the XTR2 and you would get the same test capacity as when using the cartridge in a Solo 365.
Can I use my existing Testifire smoke capsules?
No. XTR2 uses a unique smoke cartridge and is not compatible with older
TS3 capsules
How long will my TES3 last if unopened?
The shelf life of TES3 varies depending on the storage conditions it is exposed to. If stored within the recommended temperature range, the shelf life of a TES3 cartridge will extend to several years. The specified range is -10°C to 50°C (+14°F to 122°F)
I’ve left my smoke cartridge inserted and not used for a while, will it still work?
Partially used cartridges can continue to be used but may require a manual purge before use
