The HI 1292D pH electrode has been
designed for direct soil measurement. It has a conic, rugged tip and
can be directly inserted in moist or soft soil. The electrode
incorporates a temperature sensor right near the tip to enable it to
measure and quickly compensate for temperature.
For higher
degrees of accuracy, or for stony ground where the electrode may be
damaged, use the specially made HI 7051M soil preparation solution.
This solution is included in the package to help you measure pH more
precisely by dilution.
The dual-level LCD shows the pH value from
-2 to 16 with 0.01 resolution. It simultaneously displays the
temperature on the secondary level. With a menu-driven custom
microprocessor, the user is helped with clear prompts during operation
and calibration.
