Handheld TDS Pocket Meter
The Handheld TDS pocket meter is ideal for all water purification applications, wastewater regulation, aquaculture, and hydroponics. Hold function saves measurements for convenient reading and recording. Auto-off function shuts the meter off automatically after 10 minutes of non-use to conserve batteries. Measurement range is 0-9990 ppm (mg/L). From 0-999ppm (mg/L), resolution is in increments of 1 ppm (mg/L); from 1,000 to 9,990 ppm (mg/L), the resolution is in increments of 10 ppm (mg/L), indicated by a blinking 'x10' image. The meter is factory calibrated and can be recalibrated with a watch screwdriver - no need for messy solutions.
