Most meters in the range have the ability to measure single testing parameters with a few multi-parameter meters completing the selection. Each photometer is designed with an innovative optical system that offers superior performance in accuracy, repeatability, and the amount of time that it takes to do a measurement. Meters are simple and straightforward to use, with a large LCD display and intuitive interface.
Features:
Easy to use. Each photometer is very intuitive and even has a tutorial mode for step-by-step instructions. Other user friendly features include error message displays when somethings wrong, built in reaction timer from reagent addition to when measurement is to be taken and display of the unit of measure along with the reading.
Robust and waterproof. This meter will float if dropped in water and is IP67 rated. The internal optics are sealed from outside dust, dirt, and water.
Large backlit LCD display (71 x 37mm) for ease of viewing in almost all light conditions.

About the tester
Liquid Crystal Display
On/off button
pH probe with maximum and recommended immersion level
Press the on/off button to turn the meter on. All tags will be displayed. The meter will go into measurement mode with current reading and calibrated buffers displayed.
The meter has a range of 0.0 to 14.0 pH and a resolution of 0.1pH with accuracy at ?0.2pH @ 25?C. Calibration is automatic at one or two-point.
The built-in probe is for the specific application listed.
With an easy to change battery facility, the HI-981030 has an approximate battery life of 1000 hours of continuous use and has an auto-off feature enabled after 8 minutes or 60 minutes.
Featuring a liquid crystal display, the meter weighs in at 44g and measures 51 x 157 x 21mm. For best results, operate in 0 to 50?C, RH 95% max environment.
The meter is shipped with a protective cap on the electrode containing storage solution.
Procedure for Direct Ground Measurement
Verify meter is set up correctly and pH probe is calibrated.
Dig, discarding 5cm of topsoil.
Perforate the soil (with HI-721319 soil auger) to a depth of about 20cm or more.
If the soil is dry, moisten it with a small amount of tap water.
Wash the electrode with tap water (not distilled).
Insert the electrode pushing it slightly into the soil to ensure proper contact.
Observe the measurement.
Wash the electrode with tap water (not distilled) and (using a finger) gently remove any soil remaining on the electrode (avoid using a rag or cloth).
Repeat the procedure in different locations in the field.
Consider the average of the measured data.
For best results, it is advisable to measure the pH of a soil solution using a sample of soil and soil preparation solution (HI-7051). It is better to use this procedure if you have to test a stony field in which you risk damaging the electrode. Specifications Specifications

About the tester Liquid Crystal Display On/off button pH probe with maximum and recommended immersion level Press the on/off button to turn the meter on. All tags will be displayed. The meter will go into measurement mode with current reading and calibrated buffers displayed. The meter has a range of 0.0 to 14.0 pH and a resolution of 0.1pH with accuracy at ?0.2pH @ 25?C. Calibration is automatic at one or two-point. The built-in probe is for the specific application listed. With an easy to change battery facility, the HI-981030 has an approximate battery life of 1000 hours of continuous use and has an auto-off feature enabled after 8 minutes or 60 minutes. Featuring a liquid crystal display, the meter weighs in at 44g and measures 51 x 157 x 21mm. For best results, operate in 0 to 50?C, RH 95% max environment. The meter is shipped with a protective cap on the electrode containing storage solution. Procedure for Direct Ground Measurement Verify meter is set up correctly and pH probe is calibrated. Dig, discarding 5cm of topsoil. Perforate the soil (with HI-721319 soil auger) to a depth of about 20cm or more. If the soil is dry, moisten it with a small amount of tap water. Wash the electrode with tap water (not distilled). Insert the electrode pushing it slightly into the soil to ensure proper contact. Observe the measurement. Wash the electrode with tap water (not distilled) and (using a finger) gently remove any soil remaining on the electrode (avoid using a rag or cloth). Repeat the procedure in different locations in the field. Consider the average of the measured data. For best results, it is advisable to measure the pH of a soil solution using a sample of soil and soil preparation solution (HI-7051). It is better to use this procedure if you have to test a stony field in which you risk damaging the electrode.
