You will use it up before it gets really old. **Q: Whats the ppm at 19 degree Celsius? or 18.6? The box only states the ppm of the solution at 25C which is is 342 ppm** A: I doubt the actual PPM is much different between 19C and 25C. TDS/EC meters are typically sensitive to temperature and some include a temperature sensor for automatic correction. Others that don't automatically compensate for temperature and may need a "look-up" to correct during the calibration. In either case, the reference solution concentration probably doesn't change much as a function of temperature. Good luck with your TDS calibration! **Q: Can you mix this with 1000 solution to get 680ish ppm mix?** A: All you need to do to create a 680 ppm test solution is add .068 grams of table salt to 100ml of distilled or RODI water and dissolve and viola you have a 680 ppm test solution. **Q: What screwdriver is used to calibrate this meter? The little ones I've used don't turn anything.** A: Usually there is a small area on the back of the meter that takes a tiny Phillips head screwdriver. You would put the meter in the solution and then use the screwdriver to make sure it's reading 342. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***O on 16 April 2025* ### ⭐⭐⭐⭐⭐ Review *by C***Y on 7 December 2020* ### ⭐⭐⭐⭐⭐ Review *by M***U on 5 December 2022* ## Frequently Bought Together - HM Digital C342 TDS and EC Calibration Solution, 342 ppm (NaCl), 90 ml Volume, Transparent/Blue - HM Digital TDS-3 Handheld TDS Meter With Carrying Case, 0 - 9990 ppm TDS Measurement Range, 1 ppm Resolution, +/- 2% Readout Accuracy - HM Digital 1000ppm TDS Calibration Solution --- ## 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.ph/products/474461854-hm-digital-c342-tds-and-ec-calibration-solution-342-ppm](https://www.desertcart.ph/products/474461854-hm-digital-c342-tds-and-ec-calibration-solution-342-ppm) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-24*
