Ordering Information| HI99121 is supplied with HI12923 pH/temperature probe
with glass body and Quick Connect DIN connector with 1m (3.3’) cable, pH 4.01
and 7.01 Buffer sachets, HI700663 electrode cleaning solution sachet for soil
deposits, HI700664 electrode cleaning solution sachet for humus deposits,
HI7051M soil preparation solution, HI721319 ground auger, 100 mL beaker, 1.5V
AAA batteries (3), calibration certificate of meter, calibration certificate
of probe, instruction manual and HI710142 rugged carrying case.
- the HI12923 is limited to be used from 0-12 pH and from -5 to 70 °C temperature (23 to 158°F).
The HI99121 is the perfect portable pH meter for soil testing. With the
HI99121 and HI12923 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 HI12923 features a conical, rugged tip that can be directly used in soil.
A plastic auger is supplied to perforate and loosen the soil prior to sensor
measurement. Use this tool to prevent scratching the pH sensitive glass on
nutrient crystals or small pebbles.
- Optional shockproof silicon rubber boot
