Hi981030 ph тестер для почвы инструкция

Care and Maintenance

To obtain the highest accuracy for measurements it is important to follow these tips:

• Fresh buffer should be used for each calibration. Calibration is only as good as the

buffer being used. The pH buffer values change over time once the sachets are opened.

• The probe should be rinsed with purified water each time before placing in buffer or

sample to be tested.

• When the meter is not in use it is important to add several drops of storage solution to

the protective cap to keep the probe hydrated. If storage solution is not available, pH

4.01 or pH 7.01 buffer can be used.

• For improved accuracy it is recommended to calibrate in two buffers.

• It is important to calibrate and measure samples at the same temperature as there

is no temperature compensation. A dramatic change in temperature between buffer

solutions and samples to be tested will give inaccurate readings.

Refilling the Electrode

• If fouled, remove the sleeve and rinse sleeve and sensor tip with purified water.

Turn over the probe, remove the sleeve by carefully rotating it and pull straight

along the axis of the electrode. Use

care as the pH stem is made of glass.

Rinse off any traces of electrolyte gel.

• Soak the sensor tip in HI70061G,

HI700661P, HI700663P or HI700664P

cleaning solution for 20 minutes then

rinse with purified water.

• Refill the reference well with HI9071

Gelled Bridge Electrolyte.

• Replace the reference sleeve: insert and

push the sleeve onto the electrode. Make

sure the black O-ring is fixed inside the

electrode body. Any excess of gel will be

expelled from the end of the electrode through the open junction.

• Rinse any excess gel off with purified water and gently dry off

body with a soft cloth or tissue.

• Soak assembled probe in Electrode storage solution for a

minimum of 30 minutes.

• Rinse probe with purified water.

• Shake the electrode down as you would do with a clinical

thermometer to eliminate any air bubbles inside the glass bulb.

• Calibrate in fresh buffers before using for measurements.

General Description & Intended Use
The HI981030 Soil pH Tester is designed to measure the pH or acidity of the soil
as a key factor in ensuring strong and healthy plant growth. It features a single
button operation system and is easy to use. It has a compact and waterproof casing
and automatic pH calibration at one or two points. All readings are automatically
compensated for temperature variations with a built-in temperature sensor.
Direct Soil Measurement
Direct soil pH testing offers the benefit of not needing to take soil samples, as the pH
is tested right in the ground.
1. Inspect the pH probe to ensure the bridge electrolyte gel has not dried out. Refill
if necessary.
2. Calibrate the pH probe prior to measurement.
3. Using an auger (HI721319) or ruler, make a hole down into the soil (app.
20 cm). The hole needs to be the same depth each time to avoid pH discrepancies.
4. Add some distilled or deionized water to the hole; the soil should be damp but
not saturated.
5. Wash the electrode with tap water and insert into the hole.
6. Allow for the reading to develop or stabilize.
7. After measurement, gently wash off leftover soil (avoid using a cloth or a wipe).
Note: Direct soil pH testing is not recommended if the ground is stony or hardened
as the electrode can be damaged. To prepare the soil prior to measurement, take a
representative soil sample and add HI7051 Soil preparation solution.
Conical Tip: The conical tip allows for easy penetration
into damp soil. If the soil is hardened (or stony) it is best
to use an auger (HI721319 ) to make a hole for the pH
electrode to be inserted into.
Open Junction Reference: The open junction design
consists of a solid gel interface between the soil sample
and the internal Ag/AgCl reference. This interface
prevents silver from entering the sample and makes it
impermeable to clogging, resulting in fast response and
stable reading.
Polyvinylidene Fluoride (PVDF) Body: PVDF is a food-grade plastic that is
resistant to most chemicals and solvents, including sodium hypochlorite, it is also
resistant to fungal growth. It has high abrasion resistance, mechanical strength, and
resistance to ultraviolet.
Removable Polyvinylidene Fluoride (PVDF) Reference Sleeve: The PVDF
outer junction sleeve can be removed and cleaned. Once cleaned, a small amount
of supplied gel electrolyte is added and the junction is refreshed, improving the
measurement and extending the life of the tester.
