The HI99121 is the perfect portable pH meter for soil testing. With the HI99121 and HI1292D direct soil pre-amplified pH and temperature probe, users can test both the pH of soil directly or after preparation of a soil slurry with deionized water. The HI1292D features a conical, rugged tip that can be directly inserted into moist or soft soil. For harder soils, the kit includes a plastic auger to perforate the ground.

Hi83325 is a compact, multiparameter photometer for use in the environmental lab or in the field. The meter is one of the most advanced photometers available with a innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette. This meter has 9 different programmed methods measuring 8 key plant nutrient water quality parameters and also offers an absorbance measurement mode for performance verification and for users that would like to develop their own concentration versus absorbance curves. Plant nutrient-specific parameters include potassium, calcium, and magnesium
The Hi98131 GroLine pH and tds water tester features a large multi level LCD which displays both pH, EC or TDS and temperature readings simultaneously. The Hi98131 also offers the option to use a 0.7 (700 ppm) EC to TDS conversion factor. An exposed temperature sensor allows for rapid temperature compensated measurements of EC and TDS. The LCD screen has indicators for calibration status and stability. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available. The Hi98131 is a versatile pocket meter designed for hydroponics, greenhouse and agriculture applications.
The HI981420 GroLine Monitor for Hydroponic Nutrients provides around-the-clock, continuous monitoring of pH, conductivity (EC & TDS), and temperature in hydroponic nutrient solutions.
