Rated 5 out of 5 by Great inhibitor have now used this on a number of occasions in both my own and families systems, works well and on draining down system once more very little corrosion present. Help keeps the boilers in tip top condition 9 Sep 2016
Rated 3 out of 5 by Sentinel Inhibitor Bought based on reviews. Needed to use after draining system to replace TVR. Hopefully it will do what it is supposed to. At this point, unable to provide accurate ratings, beyond value for money. Otherwise, 3 stars so review is accepted! 1 Sep 2016
Rated 5 out of 5 by Best Inhibitor I added this to my central heating system a few years ago, when drained recently to change some pipe work and pump, the water was clear and pipes and pump were nice and clean, obviously doing a good job, hence buying it again with confidence it will do a good job!. 17 Aug 2016
Rated 5 out of 5 by Sentinel inhibitor Had to temporarily move a rad to make a wall repair, drained system first and water ran clean after some years in there so flushed and refilled and bought some more X100, kept it clean and scale free before so high hopes it will again. 8 Aug 2016

Answer: 
Hi there, at use concentration of X100, i.e. 1% on system volume, the effect on the specific gravity of water is negligible and therefore cannot be used to measure the level of X100.

Answers

Answer: 
Hi there, we advise that where you are adding Sentinel X100 Inhibitor to a system, you drain the system to ensure that Sentinel X100 Inhibitor is the only inhibitor present. This is because we are unable to guarantee the quality of inhibitors produced by other manufacturers and own brands.
Kind regards
