The HI 99121 kit has been designed to address the question of correct and rapid measurement of pH directly in soil. Every item in this kit has been made to facilitate measurements in the field without compromising accuracy. With HI 99121 you can test the pH of soil directly or after preparation of a diluted sample. In order to measure the pH directly, the kit includes a plastic auger to perforate the ground.
The Primo TDS tester provides a fast and dependable way to measure the Total Dissolved Solids in your water samples. It is ideally suited for the rigorous demands of water quality professionals, who will appreciate the practicality of Primo's easy-to-read LCD when demonstrating the before and after results of conditioning and filtration systems. Temperature is compensated automatically to ensure the readings are consistent to the standard or reference temperature.
The original DiST (Dissolved Solids Tester) was first introduced in 1986 by HANNA instruments. Since then, Conductivity and Total Dissolved Solids measurements have never been easier. DiST's ease-of-use, in combination with its affordability, made it the standard in EC and TDS measurement. HANNA instruments continues the tradition of innovation with the DiST 5 and DiST 6. Here at HANNA instruments we have always valued the comments and suggestions coming from our customers. For this series, we have included all the features you have asked for and more!
DiST testers are reliable, pocket-sized instruments that will give you quick and accurate readings of conductivity and TDS.
This popular line of Dissolved Solids Testers have been redesigned to offer a host of improvements.
The casing has been modified to provide increased strength, a better fit for holding and a large LCD for easy viewing. The graphite sensors provide better repeatability since they do not oxidize. The casing has been engineered to allow air bubbles to escape. The temperature sensor is exposed to provide faster response time.
The HI 98129 Combo waterproof tester offers high accuracy pH, EC/TDS, and temperature measurements in a single tester! No more switching between meters for your routine measurements. The waterproof Combo (it even floats) has a large easy-to-read, dual-level LCD and automatic shut-off. pH and EC/TDS readings are automatically compensated for the effects of temperature (ATC). This technologically advanced tester has a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode that resists contamination by salts and other substances.
When HANNA instruments introduced its first version of the pHep (pH electronic paper) in 1986, it immediately revolutionized the standard in pH measurement. pHep's ease-of-use in combination with its affordability made it possible for non-technical and technical personnel alike to measure pH on the spot, accurately and inexpensively throughout a variety of industries. Since its introduction, over 1 million pHeps have gone to satisfied customers around the world.
The HANNA instruments HYGROCHECK uses the advanved TFPC® sensing method to measure humidity and an integrated electronic circuit to perform all relative conversions. This method of Relative Humidity measurement assures a quick and accurate reading. With a complete measurement range of 10% to 90% RH and an accuracy of 3% across the entire range, HYGROCHECK is the most complete and versatile pocket-sized Hygrometer available!
HI 981404N and HI 981405N are both ideal for agricultural, horticultural and hydroponics applications where pH and TDS or pH and EC levels need to be continuously monitored for optimal plant growth. HI 981404N and HI 981405N continuously monitor and display the pH and TDS or pH and EC values of a solution on an easy to read set of dual LCD's.
