Features + Ideal for commercial use. Includes a carrying case with belt clip. + Highly efficient and accurate due to its advanced microprocessor technology. + Hold Function: saves measurements for convenient reading and recording. + Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries. + Measurement Range: 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image. + Built-in digital thermometer + Display: large and easy-to-read LCD screen. + Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver. + Also available in "x10" mode: reads in increments only of 10 ppm (0-9990 ppm).
