Ideal for commercial use, the TDS-3 includes a carrying case with belt clip. It is highly efficent and accurate due to its advanced microprocessor technology. It features a measurement range of 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1 ppm. From 1000 to 9990 ppm, the resolution is in increments of 10 ppm, indicated by a blinking image.
For use with HM Digital's PH-200 and PH-80 (as well as other brands of pH meters). Always make sure your sensor is kept in an electrode storage solution. If dry, refill the pH meter cap with the PH-STOR storage solution. The sponge should be moist (not soaking wet).
Resolution: pH 0.1 pH, 0.00–14.0 pH. Accurate to +/-0.1 pH. Hold button and auto shut-off. Automatic calibration: Auto-ranging to 4, 7 or 10 pH. Very reliable and long lasting. Low battery indicator. Clear cap to notice moisture (or lack of) on probe. Glass encased reference electrode helps retain moisture. Batteries included.
Measures pH and temperature. Auto-ranging three point calibration with digital fine tuning. pH buffer 4 solution is in a sponge embedded in a clear cap. Measurement range: 0-14 pH with a waterproof housing. Digital automatic calibration (one point), with digital fine tuning. Auto-off, data-hold functions and low battery indicator. Display: large and easy-to-read LCD screen includes simultaneous temperature reading. Factory calibrated with three-point calibration to 4, 7 and 10 pH. The meter can be recalibrated with digital calibration using the push buttons, no screwdriver needed. Includes a cap, batteries, lanyard and pH 7.0 buffer.
