6-in-1 Waterproof pH/ORP/TDS/EC (Conductivity)/Salinity/Temp Meter Pocket Size Multi-Parameter Water Quality Tester Kit Replaceable ORP Probe

I received my meter promptly within a couple of days with express shipping. Packaging was complete as advertised. Unit works well with all three electrodes - 1 for pH, 1 for ORP and 1 for Conductivity, TDS and Salinity with temperature auto correction. Calibration is easy. Good repeatability on the readings. Well worth the money for the features. Will bring it along on my travels to see what kind of water quality other countries have. It would be good if they also had a digital fluorimeter to check for the quantitive measurements of heavy metals which would complement this meter.

Nice presentation, however be aware it was not calibrated from factory as stated.Additionally, all 3 calibration solutions had the seals broken as if used for calibration already.While I was able to calibrate with some headaches it seemed to work fine.I was annoyed to see I received what appeared to be used based on the solutions being opened but the device is in perfect condition.The directions indicate to use the PH 7 solution first, then the PH 4. But whomever had it prior must have done step 1 of 2 in the calibration process because mine was looking for PH 4 instead of the Ph 7 solution. (took a couple of tries before realizing that)Note: The font is rediculously small as other users indicated so I had to take pictures of the screen upon powering on to zoom in.I will be keeping this meter for the all in one functionality. The portable carry case makes it nicely organized.

excellent investment, good product, easy to use. arrive on time.

Use it to monitor our salt water pool. The salt monitor is excellent and works well. The pH monitor is not very reliable. It never really stabilizes and keeps drifting. So what I do is measure the pH of our public drinking water and then measure the pH of the pool and see how close they are. May be I am doing something wrong.

We recently received our meter and tested it against a Hanna, and Hach meter. It measures within 0.1 pH. TDS measures great. We are very happy with our purchase.

No funciona nada,

Very nice product and delivery was very fast

Great tool for monitoring my pool and hot tub. This tool measures all significant water variables. Only down side is that you have to switch sensor tips. Not a big deal though. Would buy again.
