Only the bottom 1 inch to extend the life. If accidentally dropped in water and quickly removed likely ok. I try to only put in the probe on all my meters. **Q: Where can we buy replacement tips/probes?** A: Don't know and wouldn't buy anymore of their products. My ph pen never worked and neither did a heating pad a had gotten. Took it as a lesson, didn't even want the replacement. Went with blue lab, pricey but worth it **Q: How to calibrate temperature? My unit is reading ~8F too low** A: I tried two and both had terrible temperature accuracy. I bought a cheap $19 Taylor Precision digit thermometer which gave superior accuracy. **Q: Does this do Fahrenheit?** A: Garbage! Go with blue lab. Pricey but at least it works ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works nicely. *by L***N on May 6, 2026* Easy to use and read. Works very nicely.

Gone through 2 pens. Im VERY CAREFUL! *by R***L on March 14, 2022* Product broken only few months in. I use it evwry othwr day for qatering but for 40$ id expect a little longer use.

Couldnt get video it spazzes out from 2.00 to 5.00 ph goes everywhere ### ⭐⭐⭐⭐ Easy to Use, Easy to Read *by A***Y on November 6, 2020* The meter calibrates well. After calibtating I always put it in 7.00 buffer to confirm and it has been reliable. I like that this pH meter came with plenty of buffer solutions for calibration. Its easy to switch between between tds and pH. I prefer this type of probe over wired ones for its compact nature. I took a star off because the pH read out takes a long time to stabilize and it would have been nice if it came with electrode storage solution and a tds standard solution. ## Frequently Bought Together - VIVOSUN 4-in-1 Digital pH Meter with pH/TDS/EC/Temp Function, 0-14.0 pH Measurement Range, ±0.1 pH Accuracy Water Quality Tester for Hydroponics, Household Drinking, and Aquarium - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - General Hydroponics CALiMAGic 1-0-0, Concentrated Blend of Calcium & Magnesium, Secondary Nutrient Deficiencies Helps Prevent Blossom End Rot & Tip Burn, Clean, Soluble, 1-Quart --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/182813625-4-in-1-digital-ph-meter-with-ph-tds-ec](https://www.desertcart.pt/products/182813625-4-in-1-digital-ph-meter-with-ph-tds-ec) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-12*
