Hach Total Hardness Test Kit, Model 5-EP, Water Quality Test Kit, 145400 | Hardness Testing, Accurate Hardness Measurement, Easy-to-Use Hardness Test Kit

Excellent test kit. Just as advertised. Works well and has a nice storage kit to save for future use.

Easy to use, anyone can do it, just follow the directions which are in large type and easy to read, on a card in a plastic sleeve inside the carrying case. Hach is a trusted brand used by professional water treatment companies (I used to work for one and we used Hach products, and this same kit was in all our trucks). It gives a precise grain per gallon reading, more accurate than test strips. It arrived with just under five years left on the expiration dates of the two reagents. That allows for monthly testing of our soft (indoor) and hard (outdoor faucet) water on a monthly schedule for about four years. There are 100 pillow packs of the reagent powder and enough of the titration drops to do about 80 tests of our very hard water at 25 drops per test. So, you may run out of the drops before the pillow packs if you have very hard water like us. Resupply of the reagents is available on Amazon and elsewhere, but cost-wise, you may as well just order a whole new kit because it's only a few dollars more than ordering just the reagents. When ordered, the delivery date was shown as 12-14 days out, but I received it in 4 days, ordered on Tuesday, received on Saturday. Very happy with the purchase.

I have and use the multi-purpose test strips for checking my drinking water, but this is the correct and accurate way to measure hardness of tap water. This is a very high quality, lab-grade kit made by a German company. The instructions are easy to follow and enough reagents are supplied for 100+ tests. It is easy to accurately measure to within 1 grain per gallon, up to 30. "Hard" water is anything over 10 grains/gallon, so for the purposes of evaluating the need for and efficacy of a water softener, this is perfect.

It works just as described. The results are easy to interpret. It's a good value compared to the competition. However, it loses one star for ergonomics. The contents seem like they were grabbed off of the shelf rather than designed to work together as a package. For example, the case doesn't have a slot for each of the items inside. You have to carefully arrange everything before clamping it shut. The reagent in the foil packet must be carefully managed to ensure the contents make it into the mixing vial. I could go on, but I'm picking nits. Overall, it's a good package. No regrets.

After reading several reviews I decided on this product. It works exactly as described. We have a well with very very hard water and had purchased a really expensive water system because of that. We were still having large amounts of scale and figured the system wasn't working properly. The technicians would come out to "fix" the system and say we had one or two grains of hardness after theywere done but we were seeing no improvement. We were trying to purchase a tankless water heater and they would not even install it because when they tested our water it showed more than 25 grains of hardness. We puchased this kit and it said we had over 30 grains which is considered off the chart. We also tested the water from our water dispenser with the test kit (which someone recommended) which of course was zero. To make a long story short...this kit works perfectly especially if you just need to see if your system is working as it should be from time to time. It was simple to use and takes only a couple of minutes for results. Come to find out, our water system had a malfunctioning part (wink wink).

The HACH 145400 solution test kit is simple, easy to use and accurate. I purchased some test strips manufactured by a different company, they never changed color under any condition, sent back for a refund, waste of time and money. I have used Hach products in the past and for me, they are the BEST. Trust is key for water testings and I believe in the water testing products from HACH. Thank you!

Works great

Great system, a joy to use and much more reliable than test strips. I started with 29gpg total hardness and it was a moment of triumph when I tested again after I installed a water softener and it was down to 7gpg. Just make sure you shake/swirl after each drop.

Good quality and delivery date. Thanks :)

Works consistently well.
