Now you can test pH on the spot easily and accurately with the ExStik PH100 Waterproof pH Meter. The durable ExStik meter features a flat surface electrode for measuring pH in liquids, semi-solids, and solids. A built-in smart chip offers memory recording of 15 settings, allowing you to compare readings over time. The ExStik lets you know when the meter needs recalibration and when it's time to replace your pH electrode, so you can reuse it again and again with confidence. Because you can refill the ExStik quickly, you won't need to worry about the shelf life of its electrode.ExStik Waterproof pH MeterAt a Glance:Flat surface electrode measures pH in liquids, semi-solids, and solidsSmart chip retains up to 15 readings to show trends in acidity or alkalinityDurable, waterproof design is able to withstand harsh environmentsDual-alert system warns when to recalibrate or replace electrodeSix-month limited warranty on parts and laborProvides quick, on-the-spot pH measurements. View larger.LCD screen displays ph level and temperature. View larger.Accurately Measures pH and TemperatureThe ExStik PH100 pH meter features a flat surface electrode that measures pH in liquids, semi-solids, and solids--no more electrode breakage or clogged junctions. The ExStik can detect any level on the pH scale with a resolution of 0.01 pH and an accuracy +/-0.01 pH. The meter also measures temperatures from 23 to 194 degrees Fahrenheit (-5 to 90 degrees Celsius) with an accuracy of +/-1.8 degrees Fahrenheit. By using fresh reference solution, the ExStik achieves continuously dependable results.Refillable pH electrode maintains accuracy and removes guesswork.Reusable and Refillable ElectrodeWhen depleted, the pH electrode can be easily refilled, eliminating any concerns about electrode shelf life. One-, two-, or three-point calibration automatically recognizes buffer solutions (buffer solutions sold separately). The RENEW feature alerts you when it's time to replace the pH electrode, while the CAL alert tells you when it's time to recalibrate the meter.Built-In Smart Chip Displays and Stores ReadingsThis meter is designed to make taking accurate measurements of pH levels simpler and more useful. It has a large digital display that indicates both pH level and temperature, while at the same time allowing you to watch continuous changes in acidity or alkalinity with an analog bar graph that indicates pH trends from a neutral point (pH 7.00).The smart chip also features automatic temperature compensation, auto power-off, and low-battery indication. A display indicates when the reading is stabilized. Memory recall of up to 15 sequentially labeled readings allows you to track how readings have changed over time.Durable and ReliableThe ExStik PH100 is completely waterproof (rated IP57), and sturdy enough to withstand harsh environments. Bring it with you anywhere--it weighs less than 4 ounces and floats in water.The meter is 6-4/5 by 1-3/5 by 1-2/5 inches (H x W x D), and runs on four LR44 button batteries.Versatile Home and Commercial ApplicationsEasy to use, the ExStik meter is an invaluable tool for measuring the pH in shampoo, body wash, facial cleansers, lotions, creams, and more. Use it to monitor pools and spas, or to measure acidity and alkalinity in soil, skin, and carpeting. It's valuable in hydroponic gardening or farming. Get important readings in cement, agriculture, fish farming, wastewater, antifreeze recycling, food preparation, cleaning supplies, and manufacturing of paper, pulp, and paint.Optional Accessories to Customize Your MeterTo maximize your use of the ExStik PH100, interchangeable probes are available for chlorine and ORP (sold separately). You can also purchase a weighted base that holds a plastic sample cup and the ExStik meter, and buffer solutions for calibration.Warranty InformationThe ExStik PH100 Waterproof pH Meter is backed by a manufacturer's 6-month limited warranty on parts and labor.What's in the BoxMeter, pH electrode, bottle KCI, two reference junctions, two removal tools, sensor cap, sample cup with cap, four LR44 batteries, neck strap, and user manual.

The waterproof ExStik PH100 pH meter by Extech is an accurate, rugged and reusable stick pH meter with some unique data storage features that make it exceptionally easy to use and considerably enahnce its usability. The flat surface electrode allows you to measure pH in liquids, semi-solids, and solids and limits electrode breakage and clogged junctions. The RENEW indicator tells you when it's time to replace
your electrode. The CAL alert ensures consistently accurate readings by telling you when you need to recalibrate. A Memory feature records and recalls 15 sequentially tagged readings, so you will know how your readings have changed over time. The LCD readout displays pH, temperature and an analog bargraph that shows trends in acidity or alkalinity, and indicates when the reading is stable. 1, 2 or 3 point alibration automatically recognizes buffer solutions. Other features include automatic temperature compensation, auto power off, low battery indicator, and data hold. The PH100 comes with a protective sensor cap, sample cup, four SR44 button batteries, and a 48-inch (1.2m) neckstrap. For more convenience, purchase the the EX006 weighted base, which holds both the sample cup and ExStik meter.

Description

In just one glance the Guardian Monitor measures all three critical parameters to successful growth; pH, conductivity and temperature.

Seasonal changes, sunlight hours, wind, inherent plant growth; from vegetative to fruiting; are all influencing factors to plant growth success. More importantly...these parameters change the plants uptake and need of water and specific nutrient elements. The Bluelab Guardian is a constant indicator of the desired levels of EC, pH and temperature, enabling the grower to optimise these parameters as the crop progresses through each growing phase.

The Guardian removes the complexity of how each parameter relies on each other for outstanding growth.

Our innovative monitor is a new method to help guard the success of your crops with immediate and accurate results.

A flashing display lets you know if one parameter moves away from the ideal, allowing you to make the required adjustments quickly and effectively.

Features

• Large easy to read, Plant Safe green LED displays with adjustable brightness display.
• Selectable values for conductivity and temperature. Settings retained when power lost.
• Simple push button pH calibration system. No calibration required for conductivity and temperature.
• Silent alarm for both high and low settings. Temperature compensation.
• Water resistant design. An international power supply. 2 year warranty (6 months on probe).
