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 ### ⭐⭐⭐⭐⭐ Ok product *by M***N on 6 October 2025* Works well ### ⭐⭐⭐⭐⭐ Amazing value and warrantied *by N***T on 30 May 2025* Amazing value and came with warranty for peace of mind ### ⭐ gives poor readings even when calibrated and packs up within a month *by W***O on 20 February 2025* Even straight after calibrating this was about 5 points off no matter how many times i recalibrated and within a month of use it just started throwing up random numbers,I did keep it in storage solution and used a PH meter cleaner,It was giving readings like 9.0 for distilled water.More landfill crap ## 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.vu/products/642035146-4-in-1-digital-ph-meter-with-ph-tds-ec](https://www.desertcart.vu/products/642035146-4-in-1-digital-ph-meter-with-ph-tds-ec) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
