The Combo HI 991404 meter is designed for continuous, high accuracy pH, EC/TDS and temperature measurements. These microprocessor indicators continuously monitor the three most important nutrient parameters in hydroponics, greenhouses and horticultural applications with a single instrument. These indicators feature a large, dual-level, backlit LCD to give you instantaneous readings of pH, EC or TDS and temperature, even from a distance. At startup, these indicators perform a self-check to assure proper working condition. HI 991404 stability indicator and hold features prompt the user when to take the reading and freezes the display for easy and accurate recording. Calibration and temperature compensation is automatic, while the EC/TDS conversion factor and temperature coefficient (ß) are user adjustable for application-specific measurements. These instruments are supplied with an advanced, non-clogging double junction pH electrode and a rugged conductivity probe that will withstand even the most aggressive...

Manufacturer: Shanghai Sanxin Instrumentation Brand: Apera Instruments, LLC Model: AI209

Simply the most reliable pocket pH tester with the best value for all kinds of regular pH testing, such as hydroponics, pools and spas, water treatment, beer brewing, wine making, etc. Up to 3 points of Auto calibration and 0 to 50˚C Auto temperature compensation (ATC), ±0.1 pH Accuracy with 0 to 14.0 pH measuring range; Auto recognition and indication of stable values improves repeatability, saving you the trouble of guessing when to manually hold measurement. With an Ultra clear 180˚ viewing angle screen, it supports dual display of Temp./pH value and indications of completed calibrations (where L/M/H indicate 3 points of calibrations) and stable readings (with a smiley face). Comes with a complete Kit of premixed calibration solutions (4.00 and 7.00), 4 AAA batteries, and a lanyard all in a portable carrying case. Smart Self-diagnosis, warning of out-of-range measurement and incorrect calibrations. IP67 waterproof and dustproof, floats on water so you don't have to worry if dropped in water by ...

Manufacturer: Dwyer Instruments, Inc. Brand: Dwyer

The Dwyer® Model TDS2-10 Conductivity/TDS Testing Pen monitors both conductivity and total dissolved solids in streams, rivers, or any other body of water. It picks up impurities and dissolved solids while checking the conductivity at the same time. This pocket sized tester is constructed of a durable ABS plastic waterproof housing and 316 SS electrodes to protect against corrosion. A large LCD display is easy to read and shows both the conductivity/total dissolved solids and temperature measurements simultaneously. Since change in temperature can affect accuracy, the TDS2-10 has automatic temperature compensation. Batteries included in packaging.
