Will this meter test for hard water ?

Sort of. The meter measures total dissolved solids, whether it is calcium or sodium or potassium it does not distinguish. Hard water is hard because the calcium is dissolved in the water, therefore if you take a reading with a hard water sample, you'll get back a reading with a high number as compared to a sample from a properly working reverse osmosis system or a sample of distilled water. Likewise if you take a reading from a soft water sample you will also get a reading with a high number as the calcium has been replaced with sodium (or potassium) in softened water. The meter is primarily to confirm that your reverse osmosis system is properly working and when the membrane filter needs to be replaced.

This meter DOES NOT MEASURE pH....!!! The meter case is plastic and waterproof but it does not have a separate plastic case or box.. It is a great meter for what it was designed to do..

When I first bought this filtration system, I ran a water test. It turns out most of solubles are still in water. I suspect you will not eliminate hard water residue with this filter.

I live in Southern Calif. and our water here is HARD with dissolved salts and minerals. I bought one to use with my hydroponics water source and it DID NOT remove or change the PPM from that tested before I installed it on the hose.

Yes it will. AC or DC. Just clamp unit around positive conductor and select proper current on meter.

You have to calibrate it. It was beyond me. But i had a friend who'd done well in chemistry. He was unsuccessful in getting a reading that made sense, but I blame that more on him, than the reader. I would look for a pre-calibrated meter for someone with limited tech skills. i needed it to test PH in pond water. I have several mud ponds. The PH is a little different in each of them.

I do not know since I returned the meter after it had moisture in the display. The meter was advertised as waterproof.

My system puts out water that reads 000ppm on a quality dissolved solids meter. I would think it will remove most everything from the water.

We have used our Rainwave Flow Meter for almost a year to measure the amount of water we add to the tanks on our RV. Before using it, we checked the accuracy several times by filling 1 and 5 gallon buckets. The Meter was only off by a minuscule amount. After several uses, we checked the accuracy again, and it was pretty much the same as the initial testing. I would say that you could definitely use it to measure it from the faucet, but I have no idea how long it will remain accurate with the amount of water you will be sending through it while pressure washing. It's worth a try for $17.00. If it fails after awhile, you may require something a bit more durable.

Yes. It's a nice meter that kept working even though I sent it through the dishwasher. Please do NOT try that stunt yourself. I didn't mean to!!

Please elaborate. What are your test parameters? Are you planning to test under water?

Yes. Im a retired Elec. Contractor and got this meter for my son who is getting into the appliance repair business and knew he would need that function for troubleshooting appliances. So I researched it well. See link: http://www.testequipmentdepot.com/fieldpiece/stick-meters/hs33.htm

I think it could be, it measures acidity not salinity. I use mine for beer brewing not fish tanks. Test some tap water then test some saline water and observe the difference, if any.

yes they tested for free in my city here in Florida, they also tested for hardness which was also a concern of mine, I then installed a HALO 5 Stage water filter, this helped our concerns

I am not really familiar with the procedure for testing aquarium lights, so this is hard to answer. The bottom line is that this meter will measure for comparison light readings, based upon differences in the source of the light. I hope this response is useful.

No, it just measures conductivity and displays the results as total dissolved solids. Pure water does not conduct electricity and will read zero TDS. My tap water reads 130 and after the RO filter it reads 002.

Yes the meter should show voltage and or amps being drawn if there is a leak. Just remember that some radio's and electronic bildge pumps will pull voltage and slight amprage for memory [radio] and to check for water pressure [pump] Electronic bildge pump don't look for water level they sence water pressure to turn them on and off.
