As an alternative to the above meter, which shows readings in microS/cm, the more accurate calibration type, we also have available meters that read in parts per million, the standard US measuring system, with a slightly more coarse calibration. (PPM)
SM-401: For lower readings on the scale, from 10 – 1990 PPM, being more accurate for the lower range.
SM-402 For all readings over the whole scale, up to 10,000 PPM , more suited to bore water & hydroponics, calibrated in g/l range: 0 – 10 g/l (1 g/l = 1000 PPM)
To purchase one of these models, simply select the standard model (same price) and put under special instructions, the model number you require.
