Manufacturer: Extech Brand: Extech Model: EC500

Designed and built for a wide range of applications including process and HVAC cooling towers, industrial and commercial boilers, reverse osmosis systems, pools and spas. The ExStik II pH/conductivity meter combines a rugged flat surface pH electrode with an autoranging highly accurate conductivity cell to precisely measure conductivity, TDS, salinity, pH, and temperature. It delivers seven selectable units of measure: pH, µS, mS, ppm, ppt, mg/L, and g/L. 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,

Waterproof phtestr 10 is great for outdoor applications such as taking pH measurements in lakes and streams. Designed to Float in water, you can even attach a line to the housing for easy retrieval. Valox sensor housing resists most chemicals. The phtestr 10 has a replaceable sensor for easy maintenance. Double-junction electrode sensor handles wastewater and solutions containing sulphides, heavy metals, and TRIS. Electrode sensor offers a clog-resistant Kynar junction and a recessed, glass pH bulb to protect against breakage. The keypad clicks to confirm operation, and allows access to a variety of functions. Calibrate up to three pH points with the auto-buffer recognition at both USA and NIST standard buffers. Additional features include a automatic temperature compensation (ATC), hold function, Auto-off function, self-diagnostic error messages, and a three-segment battery-life indicator. Meter Kit adds: two single-use pouches of pH 4.01, pH 7.00, pH 10.0 buffer, and rinse solution, one sample jar, and sturdy carrying case. Versatile, compact design works in a field or laboratory setting a complete meter with key features at an economical price replaceable, double-junction electrode sensors save time and money IP67-rated housing sits flat on the table and Floats in water

The PCE-PH20S pH-Meter for soil has been developed with the purpose of finding an effective method for directly determining the pH value of soil. With the help of this pH-Meter, it is possible to quickly and accurately measure the pH value of soil or a sample taken from the soil. To do this, simply insert the electrode into loose soil and reed the pH value on the digital display. Please, take into account that the first measurement requires that there is humidity in the soil. The device is always pre- calibrated by the manufacturer. The pH Meter can be constantly recalibrated using the calibration solutions that come with the device. Calibration data remains stored in the device even when the batteries have been changed. Technical Spezification Measurement range: 0.00 to 14.00pH Resolution: 0.01pH Accuracy : ±0.07pH (between 5 and 9pH) ±0.1pH (from 4 to 4.9 and 9.1 to 10pH) ±0.2pH (from 1 to 3.9 and 10 to 13pH) Calibration: automatic, depending on the calibration solution pH value of 4, 7 or 10 Electrode : pH electrode to penetrate the ground surface Power: 4 AAA batteries Operating conditions: 0 to 60ºC /

Plants all need a particular pH to maximize the uptake of nutrient solution. Without taking control of the pH, plants can't take up the necessary elements they need for growth. The Blue lab pH Meter is the perfect, portable way to accurately measure the pH value of a solution so you can add the right amount of pH up or down to get growth back on track. Simply place the pH probe into the solution and the selected reading is displayed on screen. As the meter is handheld and does need a power supply to operate, it can be used anywhere, anytime. Calibration of the pH probe is simple as instructions are supplied on the back of the meter and the easy push button method makes this one of the simplest pH Meters in its class to use. The pH probe can be purchased as a replacement so you can keep on using the Blue lab pH Meter for years to come.

Hydrion Humidicator paper is a specially prepared, highly sensitive paper for the detection and estimation of moisture. The color changes from a deep blue to a bright rose in the presence of water or water vapor with clear, definite intermediate colors. Used to measure the relative humidity of air, it can also estimate the dew point or frost point when used with the appropriate tables. It is handy for demonstrating the need for a dehumidifier in homes, offices and storage areas. The color chart provides distinct matches in increments of 10% ranging from 20%-80%. Each roll is supplied in a jumbo size roll dispenser providing 400 tests complete with five color charts. Length x Width: 600" x 1/2". Micro Essential Labs #: HJH-650.
