Hot tub pH meter
The ideal pH value of a hot tub should be between 7.2 and 7.8; This is a necessary condition for owners of hot tubs, and you can rely on it to balance the pH value of the hot tub
Closely monitor your plants and adjust pH, PPM, and EC levels 
Check the pH value of alkaline water and food 
pH tester suitable for making food and alcohol
Most alcoholic beverages have an acidic pH value. Distilled liquor, fermented liquor, etc. have a pH value of 4.5-5.5, and beer has a pH value of 4.2-4.4. You can test the pH value of almost all surrounding liquids, such as lemon juice, milk, etc
Check the pH value of alkaline water
Assist in monitoring the water quality of RO water systems, alkaline water, bottled water, tap water, well water, and urban/urban tap water
Newly upgraded probe – no need for regular calibration 
Problems related to the use of the PH tester:
When the pH meter is turned on in air, the value will jump irregularly, which is a normal phenomenon. The value in air cannot be used as a reference.
When measuring water with the pH meter, you need to shake it gently (to remove bubbles attached to the probe), and a stabilization period is required. It is normal for the value to rise or fall during the test. Please do not enter or read the value immediately.
Matters needing attention:
– The pH meter has been calibrated before delivery, the buyer does not need to recalibrate after receiving the goods!
– Do not measure beyond the maximum immersion line or the screen

Digital Pool Water Tester: A digital pool water tester can measure pH, salinity, EC, TDS and temperature; Simply press the (MODE/CAL) button to switch and read values between pH, salinity (ppm/ppt), EC (μ S/cm/ms/cm), and TDS (ppm/ppt). Long press and hold the HOLD/TEMP button to switch between temperature and Celsius units. Satisfy regular monitoring of water quality on a daily basis, allowing you to stay informed about the water quality situation at any time
Automatic Temperature Compensation: The saltwater test kit does not need to pay attention to the temperature of the test liquid; This instrument can accurately measure sample values within the temperature range of 0 ° C-60 ° C (32 ° F-140 ° F), solving the problem of inaccuracy caused by liquid temperature changes. Whether in winter or summer, you can obtain accurate values
Humanized Design: The pool water tester backlight function ensures that you can use the product in dimly lit working environments. The HOLD/TEMP button can be used to lock the reading, and the backlight will turn off within 30 seconds. Press any key to turn the backlight back on
Easy Calibration: Supports 3-point automatic calibration, and can easily achieve automatic calibration at 4.01, 6.86, and 9.18 according to the instruction manual. Don’t worry about the calibration solution (the box is equipped with a calibration package). The equipment has been calibrated at the factory and is ready for use upon getting the device
Widely Used: The salinity tester can measure saltwater, used in swimming pools, saltwater pools, hot tubs, SPAs, aquariums, aquaculture, saltwater aquarium kits, and saltwater aquarium testing kits; The pH EC meter can measure the EC and pH of hydroponics. TDS and pH meters measure liquids such as permeate water, pool water, drinking water, tap water, irrigat

easy to use, and accurate
Excellent device for monitoring water quality. I purchased it mostly to monitor my drinking water as well as my fish aquarium. It is easy to use, compact enough and provides accurate results in seconds. Comes with calibrating powder if needed. I have not yet done calibrating, but found some videos online to help with this.

Everything I Need
Iâve been using this handy tester for my hydroponic garden, and itâs been fantastic. It gives fast, accurate readings for pH, TDS, EC, salinity, and temperature, which helps me keep my nutrient levels perfectly balanced. The constant temperature compensation ensures my readings stay consistent, even when my water temp fluctuates. Itâs easy to calibrate and the display is clear and easy to read. I’m getting serious about hydroponics and this is a must-have for keeping my plants healthy and thriving.

It works……
We had our salt water swimming pool’s water tested about a week before using this gadget. The results were pretty accurate. Why 4 stars? The usage directions were “all over the place” layout wise, with broken English. Basically, one can figure it out, but still, the directions! Hopefully, with this, we can save some trips to the pool store for testing. We maintain our own pool, typically using the paper dip strips. But the darn board that communicates with the salt cell – is being bad again – worse than household appliances! – (i think we have installed 4 boards within 15 years, ugh!) We purchased this, obviously, to monitor salt.

Accurate and easy to use
I did not buy this tool to measure my pool water but rather to test the water quality of water coming into my house and to help maintain my hydroponics vegetable grow. I tested it against a known accurate meter and they both read the same for PPS, EC and pH. I like the easy to ready readout and it appears the 3 LR44 batteries are easy to change.I looked at several other meters that look identical to this one and most are listed as IP67 waterproof. This one has rubber o-rings so I think it’s safe to say it is probably also IP67 waterproof.

A must if you have a Salt water pool system.
Works well. Measurements of TDS, EC, Salt and PH are well calibrated and the temperature matches the gauge on my pool heater. Good product.

Pretty cool water tester for measuring PH, TDS and Salinity.
Pretty cool water multi-tester. I am pretty concerned about water quality, so I have multiple water testers for different applications including PH, TDS and Salinity, but Pious tester has all these features built into a single device. Having a temperature tested in a good to have feature. I’ve tested it vs. my other devices and it seems to be pretty accurate in terms of metrics. Very fast reading, great functionality, compact size. Great value for the money.

Accurate and easy to use
Wanted a quick way to test water for my aquarium. Simple to use and accurately measures TDS, pH, and temperature. I tested against another digital meter as well as API test kit and they all came in very close for the readings.Measurement readings for TDS and pH fluctuates slightly and is slightly slow taking a few seconds to settle at a general reading, but I assume itâs always calculating the small changes in real time. The one thing I donât like is it uses three LR coin style batteries which can be expensive. The meter is bulkier than just a standard TDS meter so a standard AA or AAA would have been nice.Other than that, the meter is a nice way to get several readings at once without fiddling with other tests.

Recalibration is impossible
This ph meter is not accurate after a few weeks of use and if u follow the instructions to calibrate. It will make the pobe completely off range and no longer bebe able to recalibrate. It is now reading my6.18 solution as 9.18. Save your money and look for something else. At the minimum if u already bought it. DO NOT following the instructions providedUpdate 9/19/25Seller replaced faulty meter. Let see how the new one works so far. 5 stars for the seller

Este medidor es fiable, en auto calibración dando las ventajas de no estar continuamente calibrando manualmente. También con un manual con barios idiomas, eso lo hace versátil y muy practico. Calidad precio recomendable.

Misuratore ph veloce ed efficace, consente di testare il ph dellâacqua e non solo ed è molto reattivo senza dover aspettare lâesito. Molto meglio delle strisce che fanno perdere molto piu tempo e bisogna sempre acquistarne altre. Con questo misuratore ho risolto del tutto e ce lâho sempre a portata di mano. Funziona con delle semplici batterie e durano a lungo, lo consiglio vivamente.
