Manufacturer: Extech Instruments Brand: Extech Model: PH100

ExStik pH tester features a flat pH sensor making it ideal for testing semisolids and surfaces. Flat surface also reduces the chance of accidental breakage of the electrode tip-perfect for rugged field use! Built-in smart chip simplifies calibration and error diagnosis. CAL alert notifies you when it is time to recalibrate ensuring accurate readings. Renew indicator tells you when it is time to replace the electrode. Built-in memory recalls up to 15 sequentially tagged readings. LCD simultaneously shows pH and temperature readings, plus an analog bar graph of pH values lets you view reading trends. Waterproof tester floats in water. Flat-surface electrode is great for semisolids, solids, and surface testing Built-in memory recalls up to 15 labeled readings. Smart chip tell you when to calibrate or replace your meter

It also provides automatic temperature compensation, adjustable conductivity to TDS ratio (0.4 to 1.0), and a 0.5 salinity ratio. The unit features an analog bar graph that indicates trends, internal memory that stores up to 25 data sets, a renew feature that alerts you when the electrode needs replacement, auto power off, and a low battery indicator. It comes complete with protective sensor cap, sample cup with cap, four batteries,

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI98129 Color: Black

The Hanna Instruments HI 98129 is a multi-parameter tester that measures pH, electro-conductivity (EC), total dissolved solids (TDS), and temperature, and features automatic temperature compensation (ATC), an LCD screen, automatic shut-off, and a waterproof body that floats in water. The tester automatically compensates for the effects of temperature when taking pH and EC/TDS readings, so additional measurements and manual temperature entries are unnecessary. The HI 98129 meter has a replaceable pH electrode with an extendable cloth junction, and an EC/TDS graphite electrode that is resistant to salts and other corrosives. These features extend the life of the meter by allowing for replacement of the electrodes. Calibration is automatic at one or two points, with two sets of memorized buffer values (pH 4.01/7.01/10.01 or 4.01/6.86/9.18). The EC/TDS conversion factor and temperature compensation coefficient (&Beta) is user-selectable. The tester functions in temperatures of 0.0 to 60.0 degrees C/32.0 to 140...
