I'm not sure which one to buy for my TDS meter** A: If you are checking your water you should use the 342 ppm to calibrate as most city and well waters can run anywhere from 175-400.. If you are doing hydroponics and need to add juice (Nutz) to the water it is best to use 1000pmm cause you will be reading 800 - 2000 ppm. **Q: Does the 1000 ppm = 2mS/cm?** A: Believe so - the label says 2000 µs, guessing they mean 2000 µs/cm, so that'd be 2 ms/cm **Q: What TDS meter will the 1000 ppm calibration solution be compatible** A: its just a control substance. any meter that can measure TDS in the 1000ppm range will work with this. **Q: I’m very confused, i have a ubante tds meter and i stuck it in this 1000ppm solution and it reads exactly 500ppm. is my meter off exactly 500ppm?** A: You are correct, your meter is off exactly 500 ppm, below is a possible solution (calibrate your meter): 1) Check that the meter is set to the same salt/ionic solid as the calibration solution: (NaCl, rather than say KCl, MgCl2 or other setting allowed by the meter). 2) Before measuring greater than or equal to 0 ppm with a tds meter you will need to immerse the entire tip (containing two metal electrodes) into a first glass of distilled water (clean and dry and rinsed once with distilled water), found in a grocery store, to make sure the tip is clean. Insert the tds meter into a second glass (clean and dry and rinsed once with distilled water) of distilled water (other than that used to rinse the meter tip) and verify that the reading is 0 ppm. If the meter does not read 0ppm then refer to the tds meter manual to manually set the reading to 0 ppm. This is the first calibration point for the meter. 3) Once again, rinse the meter tip in the second glass of distilled water, then air dry the meter tip and then insert the meter tip into a portion (enough to immerse the meter tip and setting aside for future calibrations, based on the expiration date of the calibration solution) of the 1000 ppm solution poured into a third clean dry glass (that was rinsed with distilled water and then air dried). The reading should be close to 1000 ppm if the meter is calibrated correctly. 4) If the meter does not display 1000 ppm then refer to the tds meter instructions and read how to manually reset the reading on the meter to the calibration solution concentration value of 1000 ppm. This is the second calibration point. Now verify the meter functions as set by performing the following operations: 5) Once the meter is calibrated, rinse the meter tip in the second glass of distilled water in step 2), dispose of the water after removing the meter as the second glass is contaminated with 1000 ppm droplets, rinse with distilled water and refill with distilled water then immerse the meter tip into the second glass of distilled water and verify the reading is 0 ppm. 6) Rinse the meter tip in the second glass of distilled water, air dry the meter tip and, immerse the tip in the 1000 ppm solution and verify the reading is 1000 ppm. 7) To store the meter away, rinse the meter tip in distilled water and air dry. ## Frequently Bought Together - HM Digital 1000ppm TDS Calibration Solution - HM Digital C342 TDS and EC Calibration Solution, 342 ppm (NaCl), 90 ml Volume, Transparent/Blue - Apera Instruments AI1113 pH Calibration Buffer Solution Kit (7.00, 4.00), 8 oz.
