NIDO ONE V2 - Phosphoric Acid and Potassium Hydroxide

17
PHOSPHORIC ACID AND POTASSIUM HYDROXIDE
pH- (PHOSPHORIC ACID H3PO4)
USE ONLY PHOSPHORIC ACID (H3PO4) WITH A
CONCENTRATION OF LESS THAN 20%.
USE ONLY PHOSPHORIC ACID (H3PO4) AS A pH
REVERSE.
THE USE OF ANY OTHER TYPE OF ACID
WILL IRREPARABLY DAMAGE THE NIDO ONE V2
AND VOID THE WARRANTY.
It is possible to introduce phosphoric acid
(H3PO4) plus water if high concentrations are
available.
Always take extreme care when
handling acids, goggles and gloves are
recommended. NEVER allow the pH
probe to dry out as this will cause
permanent damage.
DO NOT attempt to stretch the probe cable.
DO NOT wet the BNC connector.
Phosphoric acid (H3PO4) with a
concentration of 20-30% can be diluted
in the following proportions: 50% tap
water 50% phosphoric acid.
Phosphoric acid (H3PO4) with a
concentration of 30-55% can be diluted
in the following proportions: 80% tap
water 20% phosphoric acid.
Do not use phosphoric acid with a concentration
greater than 55%.
pH+ (POTASSIUM HYDROXIDE KOH)
USE ONLY POTASSIUM HYDROXIDE (KOH) AT A
CONCENTRATION OF LESS THAN 5%.
USE ONLY POTASSIUM HYDROXIDE (KOH)
AS A pH+ CORRECTOR. THE USE OF ANY OTHER
ALKALINE SUBSTANCE WILL IRREPARABLY
DAMAGE THE NIDO ONE V2 AND VOID THE
WARRANTY.
Use pH+ (KOH potassium hydroxide) in the red
slot C in NIDO ONE V2.
It is possible to introduce potassium hydroxide
(KOH) plus water if high concentrations are
available.
Be very careful when using phosphoric
acid (H3PO4) and potassium hydroxide
(KOH). Wear safety goggles and gloves.
Keep out of the reach of children.
For potassium hydroxide (KOH) with
a concentration of 6-20%, potassium
hydroxide can be diluted in the following
proportions 70% tap water 30% potassium
hydroxide.
For potassium hydroxide (KOH) with
a concentration of 20-30%, potassium
hydroxide can be diluted in the following
proportions 80% tap water 20%
potassium hydroxide.
Do not use potassium hydroxide with a
concentration greater than 30%.
