Sentinel X100 Test Kit

Easy test kit, to confirm your inhibitor levels are OK.

Does what you need, all be it the tabs don't completely dissolve.

Expensive for what it is, but it does work - tested, needed treating, treated, tested again - all good. Job done.

Poor value, only 2 tests possible. Sent second class post. Nearly half the price on ebay.Difficult to compare colour with card on pack.However, it is the only way I can find of checking the correct dosage level.4 stars only because it takes so long (28 minutes) to dissolve the tablets.

Looks easy enough to use however no labelling on the tablets. Came with 2 strips of 2 tablets and have to use 1 of tablet 1 and one of tablet 2, however, is that both tablets from 1 strip or 1 tablet from each strip? No idea

Bit of a hit and miss, the color comparison is very subjective and the kit is very expensive for what you get. It does allow you to determine if you have sentinel in the system but it is very difficult to determine whether or not you need to add more. Very expensive piece of kit for what you get and very subjective method of measurement. Doubt if I would purchase again.

not much to say ideal for checking levels in your central heating system

Far too expensive. The two test packets are only a third of the price in merchants. The posting does not state that this packet is only good for two tests. had there been three packets in the consignment I would not be writing this
