pancellent Water Quality Test Meter TDS PH EC Temperature 4 in 1 Set for Hydroponics, Aquariums, Drinking Water, RO System, Fishpond and Swimming Pool

Pros:- Great Value for money- Comes with calibration kit for pH tester- Comes with spare batteries- Easy to read displays which are back lit- Ridiculously good value for money (£6 at the time of review - for both, so £3 each!)Cons:- pH tester does take a while (20 seconds) to find a stable readingI hope you find this review helpful.

Have bought a few of these now. We use daily but only lasts about a year

Spare batteries, test strips and two buffer solutions. Fairly easy calibration, don't understand negative reviews!

Such a bad product, looking back on it its obviously a bad product right from the moment of receiving the item. Its packed in a nice little box packed full of goodies hiding the fact you just paid £10 per meter and oh god does it show.Neither meters were anywhere near calibrated on arrival, were talking PH meter testing beside a known accurate one. this one was reading 8.7 in a ph solution of 7 neutral. After calibrating the PH pen with very poorly written instructions, it still doesnt hold its calibration, dipping it back into said calibration solutions gave a different reading every time and none of them were accurate at all. I gave in trying to calibrate it and put it back in the box.Next the TDS EC meter.................... good luck with this one, theres no mention at all of how to calibrate the ppm, theres no buffer solution with a set PPM to calibrate it too. testing the PPM of a solution that had 346ppm. this tds meter was reading 026 ppm in a solution of 346ppm. Impossible to calibrate to something as what ever it is they need you to calibrate it with isnt provided, not even in the slightest.Ive settled for cheap PH and TDS meters in the past, they arent all too bad. This one though is by far the WORST of all ive tried.DO NOT BUY, trust the negative reviews on this one and save yourself the hassle of having to return a very poor product. spend about 20 quid on a single TDS meter rather than buying 2 for 20.

There's me thinking you just turn thus on an dip it into the water. It says you have to calibrate it in distilled water.Where am u going to get distilled water from. Waste of money

Ordered these as I needed a ph and a tds meter for my aquarium tds read bang on from the box the ph probe was calibrated and read pretty accurate too. Comes with calibration fluids and spare battery's and in a nice little box does as it should

Good value for money (considering extras) but all batteries supplied were dead. Put in some fresh batteries and calibrated the PH pen. Seems to work well and is reasonably stable/consistent, but be aware you'll need to do some offset math if using standard PH 7 buffer. Not sure why they use PH 6.86, must be an origin thing. First use of the TDS/EC pen and the display kept going dead. I found the battery compartment needed a small piece of foam to stop the battery from rattling around and losing contact. To be honest the TDS/EC isn't very stable/consistent and fluctuates considerably, hence 3 stars overall.

so simple to use and read
