Designed for agricultural professionals, this meter joins the Hanna 98 series of quality pH meters which are rugged and portable with the performance and features of a benchtop. It is also an addition to the GroLine range.

Application importance

The measurement of pH in agricultural activities is very important due to the influence it has on the growth of the plant. Soil can be acid, neutral or alkaline according to its pH value. Most plants prefer a pH range from 5.5 to 7.5; but some species prefer more acid or alkaline soils. Nevertheless, every plant requires a particular range of pH for optimum growth.

Key features:

  • Waterproof – IP67 rated waterproof, rugged enclosure
  • CAL Check™ - alerts users to problems during calibration including dirty/broken electrode, contaminated buffer and overall probe condition
  • Automatic or manual temperature compensation – pH sensors incorporate a built-in temperature sensor
  • Calibration – up to a five-point calibration with seven standard buffers and five custom buffers
  • Approximately 200 hour battery life – Powered by 4 x 1.5V AA batteries
  • Clear display – Dot matrix display with multifunctional virtual keys
  • Auto hold – Automatically holds the first stable reading on the display
  • Calibration timeout – Alerts when calibration is due at a specified interval
  • Connectivity – PC connectivity via opto-isolated micro-USB with HI-92000 software
  • GLP – GLP data provides data from previous calibrations to ensure Good Laboratory Practices are met
  • Intuitive Keypad – Important and often used functions such as GLP information, help, range, calibration and backlight have a dedicated button

Supplied ready to use:

Each meter is supplied complete with sensor, calibration and cleaning solutions, beakers, PC software and connection cable, instruction manual, quick start guide and batteries in a rugged, customised carrying case.

The measurement of pH in agriculture is very important due to the influence it has on the growth of the plant. Soil can be acid, neutral or alkaline, according to its pH value. Most plants prefer a pH range from 5.5 to 7.5; but some species prefer more acid or alkaline soils. Nevertheless, every plant requires a particular range of pH, for optimum growth.

About the probe

The HI-12923 pH electrode that is supplied with the meter is uniquely designed with a conical tip and a triple ceramic junction for improved performance in soils that have a low moisture content.

The probe has a built in amplifier to reduce noise from humidity that can affect the probe connection to the meter.

The HI-12923 connects to the meter with a quick-connect, waterproof DIN connector, allowing for a secure, non-threaded attachment.

Refillable - As electrolyte is lost over time it can be replenished to extend the life of the electrode.

About the triple ceramic junction - The outer reference has three ceramic frits that allow electrolyte to flow at a high rate from the inside of the probe at the outside. A higher flow rate allows for a pH measurement of soil with low moisture.

More on the Conical Tip - The conical tip is made of durable LT glass and allows for direct measurement in soils. In the case any rocks are present, an auger is provided to make a hole for the probe.

Calibration timeout

Alerts when calibration is due at a specified interval.

pH Calibration

Choose from seven standard pH buffers and five custom values to obtain up to five point calibration and achieve high precision readings with a 0.001 pH resolution and a pH accuracy of ±0.002.

Enhanced calibration

At “out of calibration range” warning can be engaged to keep the user informed of the current calibration and help to avoid performing measurements that are out of the bracketed range.

Backlit Graphic LCD

These meters feature a backlit graphic LCD with on-screen help. The graphic display allows for the use of virtual keys to provide for a intuitive user interface.

Dedicated help key

Contextual help is always available through a dedicated HELP key. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration. The help information displayed is relative to the setting/option being viewed.

GLP

Comprehensive GLP functions are directly accessible by pressing the GLP key. Calibration data, including date, time and calibration values are stored with logged data for retrieval at a later time.

Setup screen

Our extensive setup screen features a host of configurable options such as time, date, temperature units and language for help screens and guides.

PC Connectivity

Logged data can be transferred to a Windows compatible PC with the included HI-920015 micro USB cable and HI-92000 software.

Auto hold

Pressing AutoEnd during measurement will automatically hold the first stable reading on the display.

Data Logging

The log-on-demand feature allows users to store up to 200 samples that can be later transferred to a PC with the HI-920015 USB cable and HI-92000 software.

Automatic Temperature Compensation

pH sensors incorporate a built-in temperature sensor in the tip of the electrode for a fast and accurate temperature compensated value.

Intuitive keypad

The fitted rubber keypad has dedicated keys for many important and often used functions. These meters also feature two virtual soft keys that navigate the user through setup and logging of data. The interface is intuitive for any user’s level of experience.

Long battery life

The display of the meter has a battery icon to show the remaining power. The meter uses four 1.5V AA batteries that provide up to 200 hours of battery life.
