• Economy model that is ideal for end-users.
• 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.
• 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.
• Fun, translucent blue housing that's very strong and durable.
• Includes a TDS chart sticker on the back of the meter that explains TDS values.
